Write a Java program to check whether Java is installed on your computer or not

Introduction

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
