How do I compare strings in Java?

I am having a problem with the code below; the issue is that after you don't say map the first time, it keeps repeating No try again with the input box, no matter if you type "map" or not.

 System.out.println("My cousin Diego is in trouble in the Majestic palace. But how do we get there?");
 System.out.println("Who do we call when we don't know where to go?         Huh? I didn't get that...");
 imTheMap=robotMagic.next();
 if (imTheMap.equals("map"))
 {
    System.out.println("That's right!"); //the issue is here
 }
 else 
 {
    while(imTheMap!=("map"))
    {
        System.out.println("No! try again");
        imTheMap=robotMagic.next();
    }
 }

To help format the code, try implementing a do{ }while() loop. Grab the robotMagic, and if you escape the loop congratulate the user — Zylth, Jan 10 '13 at 17:39

By changing

 while(imTheMap!=("map"))

to

 while(!imTheMap.equals("map"))

you always should use equals() method to check string equality. as in your if statement.
