java中使线程运行一定时间后停止,可以设置一个变量,当满足条件则退出线程:
import static java.lang国内手机收不到whatsapp验证码.Thread.currentThread;import java.util.concurrent.TimeUnit;public class ThreadPauseDemo{public static void main(String args[]) throws InterruptedException {Game game = newwhatapp网页版2022下载 Game();Thread t1 = new Thread(game, "T为什么登录不了whatapp网页版1");t1.start();// 现在停止Game线程System.out.println(currentThread().getName() + " is stopping game thread");game.stop();// 查看Game线程停止的状态TimeUnit.MILLISECONDS.sleep(200);System.out.whatsapp下载官网安卓手机版println(currentThread().getName() + " is finished now");}}class Game implements Runnable{private volatile boolean isStopped = false;public void run(){while(!isStopped){System.out.println("Game thread is running......");System.out.println("Game thread is now going to pause");try{Thread.sleep(200);} catch(InterruptedException e){e.printStackTrace();}System.out.println("Game thread is now resumed......&quowhatsapp怎么给别人发消息t;);}System.out.println("Game thread is stopped......");}public void stop(){isStopped = true;}}程序输出如下:
Game thread is running......main is stopping game threadGame thread is now going to pauseGame thread is now resumed.whatapp网页版协议养号.....Game thread is stopped......main is finished now

记录一个起始时间,记录一个结束时间,两个相减就是程序运行时间,代码如下
long start = System.currentTimeMillis(); // 记录起始时间try { Thread.sleep(5000); // 线程睡眠5秒,让运行时间不那么小whatsapp下载助手} catch (InterruptedException e) {e.priwhatsapp mac版刷新不出来验证码ntStackTrace();}long end = System.currentTimeMillis();// 记录结束时间System.out.println(end-start); // 相减得出运行时间得出的单位是毫秒。

在线程开始的时候,用一个变量记录当前系统时间,线程执行完后再取一次系统时间,两个时间的差就是线程执行时间了。

给你代码,这是一种方法。import java.util.Random;public class Test {public static void main(String[] args) throws Exception {TestThread t1 = new TestThread("T1");TestThread t2 = new TestThread("T2");t1.start();t2.start();t1.join();t2.join();if (!t1.isException && t2.isException) {System.out.println("abc");}}}class TestThread extends Thread {private String name = null;public boolean isException = false;public TestThread(String name) {this.name = name;}public void run() {Random random = new Random();isException = false;while (true) {try {int ranInt = random.nextInt(50whatsapp记录转移到iphonewhatsapp检索登录信息很久0);System.out.println(name + " is random : " + ranInt);if (ranInt == 250) {throw new Exception();}sleep(100);} catch (Exception e) {System.out.println(name + " is stop");isException = true;break;}}}}

两种方式实现它 知道么 线程!我把我理解的简单的很你说说也许有点用线程需要操作系统的支持,不是所有类型的计算机都支持多线程应用程序。Java程序
