我的程序一次又一次地运行而没有停止意味着该程序要求用户再次输入一个号码？有搜索批次，但没有得到基本的想法。可能是while循环将工作，但使用它两次没有得到它。

Answer 1

如何使用这样的东西，

boolean run = true;

while(run) {

   //when the condition to terminate the program is met
   //set run to false
   run = false;
}

Answer 2

while(true){

//your complete code
}

尝试再次使用while循环，如

我希望我的程序一次又一次地运行而不会停止
