JDK version question!

[Elahe Shafie]

Dear Friends,
I have JDK 1.1.8 and JDK 1.1.2 and JDK13 and since I am using Forte(JBuilder) to compile my programs, so I really don't know what version of JDK I am useing among those version!!!
Is there any way that I can check to find out?
Please advise...
Thanks a lot,
Elahe

public class WhatVersion
{
    public static void main( String[] args )
    {
        System.out.println( System.getProperty( "java.version" ));
    }
}
