Exciting New Features In Java 9

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

What Programmers Need to Know about Java 9?

Module System

The developers can now use Better Support for HTML5 and JavaScript to divide JDK into multiple modules. Each modular JAR file contains a module descriptor. The developers can define interdependency of various modules through requires statements. The modularity makes it easier for programmers to run JVM modules smoothly on small devices that lack additional memory. At the same time, they can also run only the APIs and JVM modules required by the application.

Ahead-of-Time Compilation

Java 9 improves code compilation process significantly through ahead-of-time (AOT) compilation. The programmers can leverage AOT compilation 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 overcoming major shortcomings of just-in-time (JIT) compilation. Unlike JIT compilation, AOT compilation ensures that no Java method remains uncompiled.

Real-Eval-Print-Loop Tool

Java 9 comes with a new real-eval-print-loop (REPL) command line tool - Shell. Shell is designed with features to evaluate declarative statements and expressions interactively. A programmer can use Shell to assess the quality of Java code before compilation. He can simply enter a piece of code and collect feedback. Shell even has the capability to complete tabs and add required terminal semicolons automatically. The new REPL tool makes Java compete with widely used programming languages like Python and Scala.

Better Support for HTML5 and JavaScript

The improved Javadoc documentation tool provided by Java 9 has the capability to generate HTML5 markup. Also, latest version of the programming language supports several new characters, blocks, and scripts as part of 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. The developers can further enable ECMAScript code analysis in various IDEs and frameworks directly with the parser API for Nashorn's ECMAScript syntax tree provided by JDK.

Improved Stream API

While writing Java code, programmers use strings to express calculations. Java 8 accelerated stream processing by providing the Streams API. Java 9 comes with an improved version of the Streams API that enables developers to take and drop items from Stream based on specific conditions by adding methods. Also, the improved Streams API is designed with features to create a stream for nullable value and iterate over Stream elements.

Multi-Resolution Image API

Java 9 introduces a new interface - MultiResolutionImage - to create a single multi-resolution image by encapsulating multiple images with varying resolutions. The developers can further use the Multi-Resolution Image API provided by Java 9 to get various variants of a single image. Also, they can use the API to select a particular image based on the required resolution. Hence, the Java programmers can now use a single API to create a unified multi-resolution image and get resolution-specific image variants.

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 currently not a part of Java SE. It is implemented as an incubator module which lives under the jdk.incubtor namespace. But the HTTP client API supports the latest communication standards, while overcoming the shortcomings of the HttpURLConnection API.

Stack-Walking API

While writing Java code, programmers explore ways to access and filter stack trances efficiently. The latest version of Java simplifies stack walking by providing the Stack-Walking API. The new API makes it easier for programmers to access and filter stack trace information. It further supports both short and long walks. Hence, it becomes easier for programmers to access and filter the entire stack without relying on the virtual machine to capture the stack information.

Datagram Transport Layer Security (DTLS) API

Java 9 helps developers to build secure applications by providing an API for Datagram Transport Layer Security (DTLS). The API keeps client and server communication secure by eliminating chances of data tampering, message forgery, and eavesdropping. Also, it provides communication privacy to a variety of applications that use Datagram Transport Protocol (DTP). Despite being developed based on Transport Layer Security (TLS), DTLS implements SSL protocol.

Improved Process API

Often Java programmers find it daunting to control and manage operating system processes. The Process API provided by earlier version of developers to access the native code and write additional code. But the improved Process API provided by Java 9 makes it easier for programmers to control and mange operating system processes. They can use the API to make a Java application interact with the operating system directly. Also, they can take advantage of the new methods to handle process names and states without writing additional code.

Deprecated Features

Despite providing several new features, Java 9 does not support some of the features provided by Java 8. For instance, it no longer supports Applet API. The Java web developers have to switch from Applet API to Java Web Start to launch applications from web browsers. Likewise, Java 8 speeds up development of garbage collectors in HotSpot virtual machine by deprecating Concurrent Mark Sweep (CMS) garbage collectors. While using the most recent version of Java, programmers also lack option to receive Java warnings on import statements and select JRE at launch time.

On the whole, Java 9 comes with several new features to simplify development of applications for both large and small devices. However, some of the binaries and source introduced by Java 9 are not compatible with earlier versions of the programming language. The programmers even have to make several changes to the code and upgrade libraries while migrating existing applications to Java 9. But the developers must consider upgrading their existing applications to Java 9 to take advantage of these new features and enhancements. Java developers also should use these highly recommended tools for better programming.

4 Reasons Why The Retail Industry Should Invest In Mobile App Development

Smartphones are no more a luxury, and the traditional means of shopping are not the only means. Research reveals that in the US, sales that occurred via smartphones increased by 101 percent in 2016's first quarter. The purpose of any mobile app development company is to reconstruct the traditional shopping practices consequently improving the model of mobile marketing.

A mobile app, for now, is not just the future of e-commerce but also for retail. For clients to instantly get what they want, smartphone apps serve as a personal browsing and comparison tool in their hands. Mobile shopping is earning wider popularity, for the convenience it provides. As an outcome, mobile app development companies offer high-quality and cost-effective technology solutions.

It's more of m-commerce, not e-commerce.

As per a recently conducted survey, e-commerce accounts more of 30 percent of the entire e-commerce and will grow exponentially. Mobile usage is increasing at a lightning-speed rate than any of Google's internal forecasts.

The most significant benefit of m-commerce to users is that it demands less time in transacting. Also, users can do transactions from anywhere and at any time of the day. Users enjoy more in swiping the relevant curated images as retailers make several kinds of offers for the business promotion. This is all because mobile app developers recognize the end-user needs and create customized apps that fulfill user expectations.

Buyers spend more time on Mobiles Apps Than PCs.

The m-commerce is flourishing at an escape velocity that provides a platform for this kind of technology shift. As per stats, 90 percent of all buyers spent most of their time on mobile apps. Retail apps are remarkably convenient to use and user-friendly. Buyers get access to ample of information about the business products or services quickly. 63% of Americans today prefer a mobile app for the smooth convenience that it offers.

More engaging user experience

UI-UX are essential aspects of retail app development. Users appreciate using apps as each of them has their unique features, which often follow industry standards. Research reveals that most of the buyers give an app a chance once or twice.

Creating a feature-rich retail app by the developers is growing increasingly successful as it delivers an instant impact on the first-time users. Plenty of apps are available in the play store, but only a few of them make a difference.

Mobile App growth is flaming.

There is a regular shift from mobile web to mobile app-based buying, which means that apps are more accessible and acceptable. The growth is increasing day by day, inspired by a massive expansion in the number of mobile devices. Buyers use their smartphones to see what is around them, and retailers today needs to be smarter on efficient application of mobile app and satisfying the needs of mobile-empowered buyers. For a long time, success and prosperity, it is incredibly essential for the retail app developers to create applications that have a clear-cut visibility factor.

Conclusion

Building successful and high-traffic mobile apps is the end-purpose of the development companies. Numerous buyers still relish the in-store experience as they consider touch, see, and try products that they can't do online - but that's a pretty less number of users. Retail app development benefits buyers with up-to-date market trends. Shortly, mobile retail will entirely replace the traditional retail as the favored shopping means.

PCB Repair Tools and Techniques

When physical damage usually in the form of scratched traces or mask, broken corners, lifted pads or damaged plated through holes comes up, the printed circuit board needs to be physically repaired. If desired or allowed by the customer these repairs require the proper PCB repair tools and techniques. The techniques need to be performed by those skilled in the art with experience in such repairs. Specific PCB repair tools designed to make repair technician's jobs easier and faster.

There are several techniques, many of which were developed by the military, for use in the repair of printed circuit boards. These techniques have now been assembled and are being managed by the global trade organization the IPC. The IPC procedures for repair are spelled out in IPC-7721 "The repair of printed wiring boards". This technical "how to" manual describes in detail the repair process, the tools required, the level of skill required-good, better and best- for each of the repair processes. PCB repair techniques in this document go all the way from the replating of gold fingers to solder mask repair to repair of laminate damage. The specifications call for customer involvement if a physical repair as outlined in the repair manual is required. The techniques for repair are broken down in this specification into beginner, advanced and expert PCB repair technician levels. In some cases, there may up to 4 different approved repair methods outlined in the IPC-7721, all of which will get the board back to a functioning PCB.

In addition to the "how to" instructions found in the IPC-7721 "The Repair of Printed Wiring Boards", the manual also points to the tools required to completed the suggest repair. Each of the repair processes found in the PCB repair tools and techniques manual informs the user of not only the repair techniques but also the PCB repair tools. In most cases, they are very generic tools which can be procured from a variety of sources. The photographs in the standard supporting the documentation of the specification may include a specific vendor of the tool but in some cases, the "how to" section shows a generic sketch of the tool being used. For some procedures, very specific tools from very specific vendors are shown or are referred to in the procedure being discussed.

As an example, one of the procedures found in the IPC-7721 describing PCB repairs tools and techniques, "Repair of Printed Wiring Boards" is the PCB pad replacement technique. The IPC 7721 4.5.1 Land Repair, Epoxy Method and the 4.5.2 Land Repair, Dry Film Method, both get to the same end result-the replacement of a land which has been removed usually after a rework process has been done incorrectly or handling damage. Both methods refer to the following materials: Cleaner, microscope, soldering iron, tweezer, and wipes. Then in each of the methods, specific materials specific to that method-namely adhesive, circuit frames, and adhesive film are spelled out in the detailing of each technique. Each of the process steps is enumerated in detail so that both the PCB repair process steps and the materials can be used to complete the repair.
