    Default Please describe the output of the following program!

    public class q1
    {
    	public static void JavaHungry(String s)
    	{
    		System.out.println("String");
    	}
    	public static void JavaHungry(Object o)
    	{
    		System.out.println("Object");
    	}
    	public static void main(String m[])
    	{
    		JavaHungry(null);
    	}

    Add this one also:
          Object obj = null;
          JavaHungry(obj);
    If you don't understand my answer, don't ignore it, ask a question.
