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();
      javaVersion.proceed();
   }
   
   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
