break; 语句可用于……嗯……中断迭代.例如，通过迭代，我的意思是你也可以摆脱 for.

The break; statement can be sued to... well... break out of an iteration. And by iteration I mean you can get out of a for too, for example.

您必须定义何时要中断迭代，然后执行以下操作:

You have to define WHEN do you want to break out of the iteration and then do something like this:

while(Input.hasNextInt(Input)){
   if(condition())
       break;

   count++;           

   temp = Input.nextInt();
   sum += temp;
   System.out.println(temp);
   System.out.println(count);           

 }

否则，您可以创建一个辅助方法来定义迭代是否应该继续进行，如下所示:

Otherwise, you can make an auxiliary method that defines if the iteration should keep on going, like this one:

private boolean keepIterating(Scanner in) {
    boolean someOtherCondition = //define your value here that must evaluate to false
                                 //when you want to stop looping
    return Input.hasNextInt() && someOtherCondition;
}

您必须在 while 中调用的方法:

Method that you will have to invoke in your while:

while(keepIterating()){

   count++;           

   temp = Input.nextInt();
   sum += temp;
   System.out.println(temp);
   System.out.println(count);           

}
