Finding out the Java version.

Finding out the Java version.

This is generally useful, specifically if you want to perform some operations based on Java version and so on.

public class JavaVersion
   public static void main(String args[])
      JavaVersion javaVersion = new JavaVersion();
   private void proceed()
      //This works in Java 8 and prior
      //For Java 9, there is a new api available in Runtime class
      String javaVersion = System.getProperty(“java.version”);
        System.out.println(“Java Version: ” + javaVersion); 


Expected output:

[root@mypc]# java JavaVersion
Java Version: 1.8.0_221
