Question

所以我创建了一个使用多个for循环的方法，我正在寻找一种方法，我可以让前一个for循环停止运行，这样我就可以开始使用下一个了。这是我的代码：

public void timePasses()
    {
        House callgo = new House();

        System.out.println("Shower usage:\n");    
        for (int x = 0; x < 4; x++) 
        {
        callgo.goShower();

  //Need to stop here, System.out.println("Cooker usage:\n"); only needs to print once.

        System.out.println("Cooker usage:\n");
        for (int z = 0; z < 4; z++) 
        {
        callgo.goCooker();
        }

      //this method is called as part of the simulation to trigger a new fifteen minute period
      //in the house. When it is called, it will in turn call timePasses() on all the Appliances in the House.

    }
    }

我知道可以使用多种方法但是对于规范，我需要在一个timePasses()方法中打印出所有数据，所以我想知道是否有办法可以阻止前面的循环运行，打印出我的声明并开始下一个？感谢任何帮助。谢谢。

我想你想要这个：

public void timePasses()
{
    House callgo = new House();

    System.out.println("Shower usage:\n");    
    for (int x = 0; x < 4; x++) 
    {
    callgo.goShower();

    //Need to stop here, System.out.println("Cooker usage:\n"); only needs to print once.
    }
    System.out.println("Cooker usage:\n");
    for (int z = 0; z < 4; z++) 
    {
    callgo.goCooker();
    }

  //this method is called as part of the simulation to trigger a new fifteen minute period
  //in the house. When it is called, it will in turn call timePasses() on all the Appliances in the House.
}

您可以使用break语句停止for循环。在callgo.goShower（）之后调用此break语句，并且循环将中断导致在循环结束后执行下一个语句大括号（}） callgo.goShower（）; 休息;

如何阻止for循环运行？
