9 new features in Java 9

It is not the best way that we write multi-line strings in Java. If you compare it with other programming languages, you find that in most languages, we can write multi-line strings easily using no escape sequence. Text blocks improve the way to write a multi-line string by avoiding most of the escape sequences.

Is Java SE and Java 8 same?

8 and java 8?? Java SE Development Kit 8, also known as JDK 8, has the version number 1.8. In short – 8 is product version number and 1.8 is the developer version number (or internal version number). The product is the same, JDK 8, anyways.

Java SE Runtime Environment 9 was an update to the Java Platform. This release included much awaited new features like the modularization of the Java Platform, better performance, support for new standards, and many other improvements. It also allows auto removal for automatically created classes and set the corresponding feature attributes during BeanInfo generation at runtime.

The Concurrent Mark Sweep (CMS) garbage collector is deprecated. It issue a warning message when requested on the command line. The Garbage-First (G1) garbage collector is intended to be a replacement Remote Hiring Guide: How to Ace a Remote Hiring Process? for most uses of CMS. Garbage collection logging is reimplemented by using the unified JVM logging framework. Java new version introduces a common logging system for all components of the JVM.

Starting Java 9, we can define private static as well as methods inside an interface. And these private methods will be used by the default method in the interface. Java 9 is equipped with top-notch feature sets like Jshell (REPL), Jigsaw, collections, and some API changes under the hood. In this article, we will explore all Java 9 new features extensively. Before we explain the Java 9 features in detail let us take a quick glimpse at how Java 9 helped to overcome those anomalies present in the previous versions.

  • The lines method splits the string wherever the new line character is present.
  • The idea of a light Artificial Threads which might not be supported by an OS Thread is shown by Java 19 feature prototype functionality.
  • The use of the static method is when one of the default methods is, static then in that, the case if we have to call the private static method from the static default method.
  • The second step is “Processing.” i.e., to process the data itself.
  • The first feature is defining your variables using the “var” keyword like JavaScript but not exactly like JavaScript.
  • Object-serialization clients can validate their input more easily, and exported Remote Method Invocation (RMI) objects can validate invocation arguments more easily as well.

It makes very easy for us to process the data or objects inside a collection. These streams are not the same as, which meant for reading/writing files. Here, a utility method which creates a BufferedReader object to read the content of a file is created. In earlier versions, it was complex to manage and control operating system processes by using Java programming. Now, new classes and interfaces are added to perform this task.
