停止线程

stop方法已经过时。

如何停止线程？

只有一种，run方法结束。

开启多线程运行，运行代码通常是循环结构。

只要控制住循环，就可以让run方法结束，也就是线程结束。

如：

<span style="font-size:24px;">import java.util.concurrent.locks.Condition;import java.util.concurrent.locks.Lock;import java.util.concurrent.locks.ReentrantLock;public class StopThread implements Runnable {private boolean flag = true;private Lock lock = new ReentrantLock();private Condition condition = lock.newCondition();public void run() {try{lock.lock();while(flag){System.out.println(Thread.currentThread().getName());}}finally{lock.unlock();}}public void setFlag(boolean flag) {this.flag = flag;}}</span>

<span style="font-size:24px;">public class StopMain {public static void main(String[] args) {StopThread st = new StopThread();Thread t1 = new Thread(st);Thread t2 = new Thread(st);t1.start();t2.start();int num = 0;while(true){if(num++ == 60){st.setFlag(false);break;}System.out.println(Thread.currentThread().getName()+"..."+num);}}}</span>

特殊情况：

当线程处于了冻结状态，

就不会读取到标记，那么线程就不会结束。

当没有指定的方式让冻结的线程恢复的运用状态时：这是需要对冻结进行清除

<span style="font-size:24px;">import java.util.concurrent.locks.Condition;import java.util.concurrent.locks.Lock;import java.util.concurrent.locks.ReentrantLock;public class StopThread implements Runnable {private boolean flag = true;private Lock lock = new ReentrantLock();private Condition condition = lock.newCondition();public void run() {try{lock.lock();while(flag){try {condition.await();} catch (InterruptedException e) {System.out.println(Thread.currentThread().getName()+"...Exeption");flag = false;}System.out.println(Thread.currentThread().getName());}}finally{lock.unlock();}}}</span>

<span style="font-size:24px;">public class StopMain {public static void main(String[] args) {StopThread st = new StopThread();Thread t1 = new Thread(st);Thread t2 = new Thread(st);t1.start();t2.start();int num = 0;while(true){if(num++ == 60){t1.interrupt();t2.interrupt();break;}System.out.println(Thread.currentThread().getName()+"..."+num);}}}</span>
