Java is the world’s most prevalent programming language. Java SE 9, the most recent release, includes various upgrades to the earlier java programming, JVM, Tools and libraries. It is the outcome of an industry-wide development effort between Oracle specialists and members of Java developer community through the Open JDK Community and the JCP.
In September, Oracle released Java SE 9 with more than 150 new features. The most recent version of the widely used programming language comes with several new features and APIs to quicken development of applications for both large and small devices. In the meantime, the features provided by Java 9 help programmers to enhance application’s performance, security, and maintainability. Consequently, it becomes fundamental for programmers to understand some of the key highlights provided by Java 9. Some enticing new features that comes with Java 9 are:
(2) Ahead-of-Time Compilation: Java 9 enhances code aggregation process altogether through early AOT assemblage. The developers can take advantage of AOT compilation and compile Java classes into native code even before the virtual machine dispatches them. AOT compilation enhances the execution of both large and small applications by beating real inadequacies of without a moment to spare (JIT) aggregation. Unlike JIT compilation, AOT compilation guarantees that no Java strategy remains uncompiled.
(3) Real-Eval-Print-Loop Tool: Java 9 accompanies another real-eval-print-loop (REPL) command line tool — Shell. Shell is drafted with features to assess declarative statements and expressions intuitively. A developer can use Shell to survey the trait of Java code before compilation. He can essentially enter a bit of code and gather input. Shell even has the capability to complete tabs and include required terminal semicolons naturally. The new REPL tool influences Java to rival broadly with widely used programming languages like Python and Scala.
(4) Improved Process API: Often Java application Development Company think that it’s overwhelming to control and manage operating system processes. The Process API provided by earlier version needs additional code to access native code. But the enhanced API offered by Java 9 makes it less demanding for programmers to control and manage operating system directly. They can utilize the API to influence a Java application to associate with the working framework specifically.
(5) Deprecated Features: Regardless of several new highlights, Java 9 does not support few features that was offered by Java 8. For example, it does not support Applet API. The developers need to change from Applet API to Java Web Start to launch applications from web browsers. In same manner, Java 8 accelerates development of junk collectors in HotSpot virtual machine by derogate Concurrent Mark Sweep (CMS) trash collectors. While utilizing the latest adaptation of Java, programmers additionally need choice to get Java warnings on import statements and select JRE at launch time.
All in all, Java 9 accompanies several new features to simplify development of applications for both large and small devices. However, some of the features are not compatible with earlier versions. The developers even need to roll out few changes to the code and redesign libraries while moving existing applications to Java 9. It is advisable to hire expert professionals for Java development solutions to avoid any discrepancy in building an application using Java 9.
