Java command line argument test

When I run the following code

public class Test {
    public static void main(String[] args) {
        System.out.println(args[0]);
        System.out.println("testing");
        System.out.println(args[0] == "testing");
    }
}

using

java Test testing

at the command line, it prints the following:

testing

testing

false

Why is the third printed line not 'true' when printed lines 1 and 2 seem to be the same?
