In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

public class Javaexcercise {
public static void main(String[] args) {
    System.out.println("\nJava Version: "+System.getProperty("java.version"));
    System.out.println("Java Runtime Version: "+System.getProperty("java.runtime.version"));
    System.out.println("Java Home: "+System.getProperty("java.home"));
    System.out.println("Java Vendor: "+System.getProperty("java.vendor"));
    System.out.println("Java Vendor URL: "+System.getProperty("java.vendor.url"));
    System.out.println("Java Class Path: "+System.getProperty("java.class.path")+"\n");
 }
}

Result:

Java Version: 11.0.13Java Runtime Version: 11.0.13+8-Ubuntu-0ubuntu1.20.04Java Home: /usr/lib/jvm/java-11-openjdk-amd64

Java Vendor: Ubuntu

Java Vendor URL: https://ubuntu.com/
