You're looking for this on the command line (for a class called MyClass):

On Unix/Linux:
$ javap -verbose MyClass | grep "major"

On Windows:
$ javap -verbose MyClass | findstr "major"

You want the major version from the results. Here are some example values:

public class Version {
	public static void main(String[] args) {
        //  System.out.println("Enter your name");
        // Scanner scan = new Scanner(System.in);
        int a, n;
        n = args.length;
        for (a = n-1; a > -1; a--) {
            System.out.println(args[a]);}
        String version = Runtime.class.getPackage().getImplementationVersion();
        System.out.println(version);
