如何使用scanner对象比较java中的字符串

Question

我有一个关于如何使用scanner对象在java中比较字符串的问题？ 。我要比较的东西分别是4个州和首都。

这是我到目前为止所尝试的：

    String myString1 =  new String ("state");
    String myString2 =  new String ("capitalstate");

    System.out.println ("input state");
    myString1=input.next(); 


    if (myString1.equals("malaysia"))
    {
        myString2 = "kuala lumpur";
        System.out.println ("capital state for " +myString1+ " is " +myString2);
    }



    else if (myString1.equals("south korean"))
    {
        myString2 = "seoul";
        System.out.println ("capital state for " +myString1+ " is " +myString2);
    }

您的代码可以是以下内容，应该可以正常运行：

Scanner input = new Scanner(System.in);
String myString1 =  new String ("state");
String myString2 =  new String ("capitalstate");

System.out.println ("input state");
myString1=input.next(); 

if (myString1.contains("malaysia"))
   {
     myString2 = "kuala lumpur";
     System.out.println ("capital state for " +myString1+ " is " +myString2);
    }

else if (myString1.equals("south korean"))
    {
      myString2 = "seoul";
      System.out.println ("capital state for " +myString1+ " is " +myString2);
    }
