Java - 方法sleep（int）未定义Thread类型 [英] Java -The method sleep(int) is undefined for the type Thread

问题描述

我收到错误：对于Thread类型，方法sleep（int）是未定义的。我认为sleep方法在Java中的Thread类中。

I'm getting an error: The method sleep(int) is undefined for the type Thread. I thought the sleep method is in the Thread class in Java.

import java.util.Random;

public class Thread implements Runnable {

    String name;
    int time;
    Random r = new Random();

    public Thread(String s){
        name = s;
        time = r.nextInt(999);
    }

    public void run() {
        try{
            System.out.printf("%s is sleeping for %d\n", name, time);
            Thread.sleep(time);
            System.out.printf("%s is done", name);
        } catch(Exception e ) {
        }
    }
}

推荐答案

您实现了自己的类 Thread 并尝试调用 sleep on，失败，导致 sleep 在您的课程中未定义。你的班级基本上影响了java的线程类。

You implemented your own class called Thread and try to call sleep on it, which fails, cause sleep is undefined in your class. Your class basically shadows java's Thread class.

以不同方式调用你的类（即 MyThread 甚至更好 MyRunnable ，如owlstead所述）或致电 java.lang.Thread.sleep（）直接。

Call your class differently (ie. MyThread or even better MyRunnable, as noted by owlstead) or call java.lang.Thread.sleep() directly.
