Re: garbage collection

Hi,

I am studying for my SCJP and I have a question that I am unsure off.

"When will the string object created intially as arg1 be garbage
collected?

package com.tnt.august.eighth;

public class Myclass (
    public static void main(String [] args) {
        String msg;
        String pre = "Trick ";
        String mid = "or " ;
        String post = "Treat. ';

        String arg1 = new String (pre +
                                   mid +
                                post);

        msg = argl;
        arg1 = null;
        msg = pre + mid + msg;
        pre = null;
        mid = null;

        System.out.println (msg);

        msg = null;
        post = null;
        args = null;

    }
}
