我怎么能解决这个副作用？

Question

  

可能重复：
  How do I compare strings in Java?

我遇到以下代码的问题;问题是，在你第一次没有说地图之后，无论你输入的是“地图”，它都会在输入框中不断重复No try again。

 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();
    }
 }

Answer 1

通过更改

 while(imTheMap!=("map"))

到

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

总是应该使用equals（）方法来检查字符串相等性。就像你的if语句一样。
