java - 简单的 Java 倒数计时器

Question

我正在用 Java 做一个学校项目，需要弄清楚如何创建一个计时器。
我正在尝试构建的计时器应该从 60 秒开始倒计时。

Answer 1

您可以使用:

 int i = 60;
 while (i>0){
  System.out.println("Remaining: "i+" seconds");
  try {
    i--;
    Thread.sleep(1000L);    // 1000L = 1000ms = 1 second
   }
   catch (InterruptedException e) {
       //I don't think you need to do anything for your particular problem
   }
 }

或者类似的东西

编辑，我知道这不是最好的选择，否则你应该创建一个新类:

执行此操作的正确方法:

public class MyTimer implements java.lang.Runnable{

    @Override
    public void run() {
        this.runTimer();
    }

    public void runTimer(){
        int i = 60;
         while (i>0){
          System.out.println("Remaining: "+i+" seconds");
          try {
            i--;
            Thread.sleep(1000L);    // 1000L = 1000ms = 1 second
           }
           catch (InterruptedException e) {
               //I don't think you need to do anything for your particular problem
           }
         }
    }

}

然后你在你的代码中做:
线程线程=新线程(MyTimer)；
