Exciting new features in Java 9



Oracle released Java SE 9 in September with over 150 new features. The latest version of the widely used programming language comes with several new features and APIs to accelerate application development for both large and small devices. At the same time, the features provided by Java 9 help programmers improve application performance, security, and maintainability. Hence, it becomes important for programmers to understand some of the key features provided by Java 9.

What programmers need to know about Java 9?

Modular system

Developers can now use improved HTML5 and JavaScript support to split the JDK into multiple modules. Each module JAR file contains a descriptor for the module. Developers can define interdependencies between different modules using the requires statements. Modularity makes it easy for programmers to smoothly run JVM modules on small devices that lack additional memory. At the same time, they can also run only those APIs and JVMs that are required by the application.

Ahead compilation

Java 9 dramatically improves the compilation process of your code through pre-compilation (AOT). Programmers can use AOT compilation to compile Java classes into native code even before the virtual machine launches them. AOT compilation improves the performance of both large and small applications by eliminating the major disadvantages of JIT compilation. Unlike JIT compilation, AOT compilation ensures that no Java method is left uncompiled.

Real-Eval-Print-Loop Tool

Java 9 comes with a new command line tool real-eval-print-loop (REPL) – a wrapper. The wrapper is designed with functions for interactively evaluating declarative operators and expressions. The programmer can use Shell to evaluate the quality of Java code before compiling. He can simply enter a piece of code and collect feedback. Shell even has the ability to auto-complete tabs and add semicolons as required. The new REPL tool is forcing Java to compete with widely used programming languages ​​such as Python and Scala.

Better HTML5 and JavaScript support

The enhanced Javadoc documentation tool provided by Java 9 has the ability to generate HTML5 markup. In addition, the latest version of the programming language supports several new characters, blocks, and scripts as part of the Unicode 8.0 encoding standard. At the same time, Java 9 comes with an improved and lightweight JavaScript engine that makes it easier for programmers to embed JavaScript code in Java applications. Developers can optionally enable parsing of ECMAScript code in various IDEs and frameworks directly by using the Parser API for the Nashorn ECMAScript Parse Tree provided by the JDK.

Improved Stream API

When writing Java code, programmers use strings to express computations. Java 8 has made stream processing faster by providing the Streams API. Java 9 comes with an improved version of the Streams API that allows developers to take and remove elements from a Stream based on certain conditions by adding methods. In addition, the improved Streams API is designed with functions for creating a stream for nullable values ​​and iterating over Streams.

Multi-Resolution Image API

Java 9 introduces a new interface – MultiResolutionImage – for creating a single image at multiple resolutions by encapsulating multiple images at different resolutions. Developers can optionally use the Java 9 Multi-Resolution Image API to get different variations of a single image. In addition, they can use the API to select a specific image based on the required resolution. Consequently, Java programmers can now use a single API to create a unified image at multiple resolutions and get variations of images at a specific resolution.

http: // 2 client API

Java 9 completely changed the way applications make HTTP calls. It replaces the HttpURLConnection API with a new HTTP client API. The HTTP client API supports both http: // 2 and WebSockets. However, the API is not currently part of Java SE. It is implemented as an incubator module that resides in the jdk.incubtor namespace. But the HTTP client API supports the latest communication standards, overcoming the disadvantages of the HttpURLConnection API.

Stack-Walking API

When writing Java code, programmers explore ways to access and filter stack transfer efficiency. The latest version of Java simplifies stack traversal by providing the stack traversal API. The new API makes it easier for programmers to access and filter stack trace information. In addition, it supports both short and long walks. Consequently, it becomes easier for programmers to access and filter the entire stack without relying on the virtual machine to collect stack information.

Datagram Transport Layer Security (DTLS) API

Java 9 helps developers build secure applications by providing APIs for Datagram Transport Layer Security (DTLS). The API ensures the security of communication between the client and the server against the possibility of data tampering, message tampering and interception. In addition, it provides communication confidentiality for a variety of Datagram Protocol (DTP) applications. Although DTLS is designed around Transport Layer Security (TLS), it implements SSL.

Improved process API

Often Java programmers find it difficult to control and manage operating system processes. A process API provided by earlier developers for accessing native code and writing additional code. But the improved Process API provided by Java 9 makes it easier for programmers to monitor and control operating system processes. They can use the API to make the Java application interact directly with the operating system. In addition, they can take advantage of new methods for handling process names and states without writing additional code.

Deprecated functions

Despite the provision of several new features, Java 9 does not support some of the features provided by Java 8. For example, it no longer supports the Applet API. Java web developers must switch from the Applet API to Java Web Start in order to launch applications from web browsers. Likewise, Java 8 accelerates the development of garbage collectors in the HotSpot VM by excluding the Concurrent Mark Sweep (CMS) garbage collectors. With the most recent version of Java, programmers also have no way of getting Java import warnings and choosing a JRE at startup.

Overall, Java 9 contains several new features to make it easier to develop applications for both large and small devices. However, some binaries and source code introduced in Java 9 are incompatible with earlier versions of the programming language. Programmers even have to make a few code changes and update libraries when porting their existing applications to Java 9. But developers should consider upgrading their existing applications to Java 9 to take advantage of these new features and improvements. Java developers should also use these highly recommended tools for better programming.

The rapidly changing landscape of mobile HTML5




According to the latest usage statistics published on W3Techs, over 54% of all websites currently use HTML5 as their markup language. The effectiveness of HTML5 can also be gauged by the fact that it is currently used by YouTube as its default video player. Likewise, Facebook switched from Flash to HTML5 for all of its videos. Several surveys also found that a large percentage of developers today prefer HTML5 mobile apps over native and hybrid mobile apps.

HTML5, along with CSS3 and JavaScript, helps developers create responsive websites that look good on every device. In addition, HTML5 apps provide an optimal viewing experience on desktops, laptops, smartphones, tablets, and phablets. Unlike native and hybrid mobile apps, HTML5 mobile apps run in web browsers. Major operating systems and web browsers currently support version 5 of HTML. Consequently, it becomes easier for developers to manage, update and distribute mobile applications without any problems. There are also a number of reasons why many analysts believe HTML5 is constantly changing the mobile app development landscape.

Why is HTML5 changing the mobile app development landscape?

Simplifies the development of cross-platform mobile applications

Developers are currently building mobile apps to increase revenue, targeting multiple mobile platforms. The functions and native programming language of individual mobile platforms differ. Therefore, developers have to spend additional time and effort creating their own applications for each target mobile OS. But HTML5 makes it easier for developers to build cross-platform mobile apps using widely used web technologies. Going forward, programmers can write a single codebase and reuse the same codebase across different mobile platforms.

Overcoming mobile and OS fragmentation

When developing mobile applications, it is difficult for developers to address key issues such as fragmentation of mobile devices and OS. For example, they have to build apps targeting a variety of devices running the latest iOS or Windows Phone. Likewise, they must ensure that the app works flawlessly on a wide variety of devices running on different Android models. HTML5 allows developers to create apps that work seamlessly on every mobile device, platform, and web. Consequently, it becomes easier for HTML5 developers to focus on the functionality and functionality of an application instead of worrying about device and operating system fragmentation.

No need to learn the native language of each platform

When developing their own applications, developers must use the native programming language of each target mobile platform. For example, they have to write Android apps in Java and iOS apps in Objective-C or Swift. But HTML5 allows developers to make a web application available on many mobile platforms without having to use multiple programming languages. They can simply use commonly used web technologies like HTML5, CSS3 and JavaScript to create various cross-platform mobile apps and responsive websites.

Easy to maintain and update apps

As noted earlier, HTML5 allows programmers to write a mobile application once and deploy it to multiple mobile platforms. Hence, developers must maintain a consistent codebase. They can easily make changes to the code so that the application is bug-free and works flawlessly on many platforms. Likewise, a single codebase makes it easy for programmers to add new features and functionality to an application without forcing users to update their applications. They can even easily modify the content of the apps to keep users interested and interested.

Improving application visibility

Users can now choose from millions of mobile apps available in the App Store, Google Pay and Windows Store. Hence, companies must implement a robust marketing strategy to improve the visibility and accessibility of their applications. Likewise, they must effectively promote paid apps in order to convince users to prefer them to similar free apps. But it’s often easier for businesses to distribute and sell HTML5 apps. Unlike native apps, HTML5 apps don’t need to be submitted to various app stores. Open Distribution Mode further helps companies improve the visibility and discoverability of their applications while reducing competition.

Ability to use many robust HTML5 frameworks

Developers also have the opportunity to dramatically reduce development time for mobile apps by leveraging robust HTML5 frameworks. Depending on the nature and requirements of the project, they have the option to choose from several HTML5 frameworks including Kendo UI, Ionic, Intel XDK, Sencha Touch, and Framework 7. Developers can also use PhoneGap to internally package and distribute HTML5 applications. them through the app stores.

Reduce development costs

HTML5, CSS3 and JavaScript are open source web technologies. Thus, these technologies help enterprises to significantly reduce the cost of developing cross-platform mobile applications. The enterprise also has the ability to build hybrid mobile apps using the skills of existing web developers. Any developer familiar with these widely used web technologies can easily create many mobile applications. In addition, HTML5 frameworks enable developers to build robust applications without wasting extra effort and time. Reduced development time and simple distribution model further help enterprises to dramatically reduce time to market.

However, developers still need to solve a number of problems when developing HTML5 applications. For example, the slow execution speed of HTML5 affects the performance of mobile applications because most mobile devices have limited processing power. Likewise, HTML5 mobile apps cannot use device and operating system specific features. Additionally, these apps lack monetization and marketing opportunities as there is no centralized store for these mobile apps. Many developers still choose to develop HTML5 mobile apps in order to make new apps available across multiple platforms in a shorter time frame.

Importance of WordPress Rest API




Importance of WordPress Rest API

When developing web applications using WordPress, developers connect the application to third-party programs and services through specific application programming interfaces (APIs). In addition, they use various APIs to improve the functionality of the WordPress application and the user experience. The WordPress REST API allows programmers to connect their application to other software and services in an easier and more efficient way. Developers can use a plug-in to link their WordPress application with other websites and services, overcoming differences in data form and back-end programming languages.

Understanding important aspects of the WordPress REST API

JSON data format

They can use a plugin to force a WordPress application to interact with third-party software and services by sending and receiving JavaScript Object Notation (JSON) objects. JSON is a modern and readable data format. In addition, JSON has encoders and decoders for the most widely used programming languages. Hence, the WordPress application and third party software can exchange data in a mutually understandable format. Developers can also easily connect their WordPress application to a variety of software and services by writing simple JavaScript code.

REST methodology

WordPress has developed the plugin as a generic connector using the Representative State Transfer (REST) ​​methodology. Besides a simple data format, REST also allows developers to use commonly used HTTP methods such as POST, GET, DELETE, and PUT. At the same time, the methodology can facilitate the exchange of data in both XML and JSON format. The REST methodology simplifies communication between two programs. In addition, it allows the WordPress application to communicate with other websites and services in both XML and JSON format.

Compatibility with other web programming languages

When developing websites with WordPress, programmers must write code in PHP. PHP is currently the most popular server side programming language. But it lacks many of the advanced features provided by modern programming languages ​​such as Ruby, Java, and C #. Consequently, many developers nowadays prefer to write web applications in modern programming languages. The WordPress REST API will make it easier for programmers to connect WordPress applications to other websites and services, regardless of their server-side programming language. A seamless connection can further help programmers eliminate common compatibility issues.

Contributing to the development of custom web applications

The WordPress REST API will make it easy for developers to create custom web applications according to various business requirements. Because they can use the plug-in to access third-party information and resources from many sources, developers can easily improve the look and feel of a web application. Many developers can create their own websites without relying on the traditional WordPress interface. Going forward, they can use this tool to build the front-end and back-end of a WordPress application in a completely new and more efficient way.

Optimizing WordPress Apps for Mobile Devices

Currently, major mobile operating systems such as iOS and Android support the JSON data format. Since the WordPress REST API allows applications to exchange data in JSON format, it becomes easier for programmers to optimize WordPress applications for mobile devices. Many developers can use this plugin to develop and run mobile apps with WordPress. They can further develop and deploy efficient mobile apps using WordPress as a back-end. The WordPress REST API will allow many developers to build their own mobile apps using their existing coding skills.

Time to migrate from Magento 1 to Magento 2




More than 2.5 years have passed since the separation of eBay and Magento. Magento released a newer version of the platform right after the split. As is often the case, a crisis reveals the best in people. Since Magento was about to sell out, teams had to think outside the box. They had to bring fresh ideas when they were filming the billboards provided by eBay.

However, let’s not judge a major Magento release from an irrational point of view. Well, yes, they had to create a product with a startup. And that’s when the pros stretch the muscles. However, when we analyze some of the features described in Magento 2 as a Magento extension developer, there is no doubt that this is an improved version among them.

Some of the main features of Magento 2.x are:

A) Magento 2 – For tomorrow:

If you are running your online store on Magento 1.x platform, you should face certain performance issues. You can more effectively manage issues like page load times, security fixes, image optimizations, and heavy JavaScripts using Magento 2.x.

Third party modules on the server

When using Magento 2.x, store owners do not need to install third-party modules on the server.

Page load times and security fixes

By using Magento 2.x, store owners can improve site speed as it supports the latest PHP version. And they already have security fixes.

Image optimization

In Magento 1.x, you need to manually optimize your images. However, Magento 2.x has built-in functionality to manage image optimization without external support.

Minified JavaScript

Great relief. An important UX improvement is inline JavaScript. This ensures that developers do not need to perform tedious and unnecessary operations in the browser.

B) Search Engine Optimization and Security Improvement:

When it comes to these two critical backend requirements, Magento 2.x is far superior to Magento 1.x. Password hashing algorithms effectively protect the site. Built-in rich category page descriptions help improve the overall page optimization process.

C) Brand new admin panel:

Improved information search, general store management and admin panel navigation.
Simplified product upload process as well as images and text, you can now upload videos too
Your Magento 2.x dashboard displays Top and Least Searched Items, Latest Orders, Average Order Amount, Top Selling Products, Premium Customers, Products you need to ship and Total Quantity, Tax Data, etc. …
Manage Customers vs. Orders columns from the front-end without developer assistance.
Advanced content preparation
Advanced data import function
Magento 1.x to Magento 2.x data migration tool
New marketing tools section for SEO, promotions, user generated content, and more.

D) Solution to split database performance (Enterprise Edition only)

Magento 2 uses separate master databases for orders, checkout and product data. The same goes for all functional areas. This allows store owners to improve the scalability and performance of their website. But you can only take advantage of this feature if you buy Magento Enterprise Edition. Magento CE (Community Edition) only uses one database.

Better performance

Magento 2.x can help you broaden your business horizons and help you manage your store to the best of your ability. It has a brand new admin panel design that offers an interface for your website. You can use the recently introduced visual design editor and install blocks and containers on your website without having any technical knowledge.

Increased scalability

Magento 2.x comes with improved indexes with efficient updates. This improves the performance of your website by increasing the speed of requests. Magento 2.x and Varnish Cache are integrated, which means you can reduce server load and speed up page load times. Administrator users can also create and edit products without worrying about data conflicts.

Best conversion

With Magento 2.x, shoppers are bound to have a great shopping experience. Online store owners can display their products with descriptions, images and videos. In addition, since the website is responsive, they can view it from any device, including a smartphone, tablet, or PC. This helps to boost your conversion rates to a large extent.

Easy and smart upgrades

Magento 2.x has updated information about update compatibility and version control policies. Thus, apart from improving the basic Magento software, installing and updating Magento 2.X is easier compared to Magento 2.x. Magento 2.x export / import functionality allows you to export customer data, records as well as inventory data and import it into Magento 2.x.

Swift theme customization

As far as the core theme goes, Magento 2.x uses native LESS and CSS instead of Bootstrap. It also supports CSS processing, which helps speed up page loads, improve performance, and make your system SEO compliant.

Migrating from Magento 1.x to Magento 2.x is always a good decision as it gives businessmen a higher ROI. And so you know, Magento will only support M1 until November 2018. After that, you will rarely receive any feature or feature updates from the M1.
