Java如何使用Thread类的sleep方法？
下面是另一个使用Thread.sleep()方法的示例。在这个例子中，我们创建了ThreadSleepAnotherDemo的两个实例，我们给每个线程一个名称和休眠间隔，这样我们就可以看到如何执行线程。
package org.nhooo.example.lang;
import java.util.Calendar;
public class ThreadSleep implements Runnable {
private String threadName;
private long sleep;
public ThreadSleep(String threadName, long sleep) {
this.threadName = threadName;
this.sleep = sleep;
}
// 启动线程时将调用run()方法。
public void run() {
System.out.println("Start thread [" + this.threadName + "]");
try {
while (true) {
// 将线程暂停“睡眠”毫秒。"sleep" milliseconds.
Thread.sleep(this.sleep);
System.out.println("[" + threadName + "]" +
Calendar.getInstance().getTime());
}
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Finish thread [" + this.threadName + "]");
}
public static void main(String[] args) {
Thread thread1 = new Thread(new ThreadSleep("FirstThread", 1000));
Thread thread2 = new Thread(new ThreadSleep("SecondThread", 3000));
// 启动线程
thread1.start();
thread2.start();
}
}这些是上面的代码片段生成的示例输出：
