转: Java安全停止线程方法

1.早期Java提供java.lang.Thread类型包含了一些列的方法start(), stop(), stop(Throwable) and suspend(), destroy() and resume()。，Sun公司的一篇文章《Why are Thread.stop, Thread.suspend and Thread.resume Deprecated? 》  
2.使用volatile变量来设置Thread的run的循环条件，保证变量同步性  
      
public class JavaTest extends Thread{  
private volatile boolean isRun = true;  
public static void main(String[] args) {  
JavaTest thread = new JavaTest();  
thread.start();  
thread.close();  
}  
@Override  
public void run() {  
while (isRun) {  
//dosomething  
}  
}  
public void close() {  
this.isRun = false;  
}  
}  
3.使用interrupt()来中止非运行状态的线程，如wait()和sleep()状态的线程，此时可利用interrupted来终止线程  
public class JavaTest extends Thread{  
private volatile boolean isRun = true;  
public static void main(String[] args) {  
JavaTest thread = new JavaTest();  
thread.start();  
thread.close();  
if (thread != null) {  
thread.interrupt(); //外围调用关闭  
}  
}  
@Override  
public void run() {  
while (isRun) {  
//dosomething  
  
try {  
wait();   //同样适用于sleep等状态  
} catch (InterruptedException e) {  
//catch Exception  
}  
}  
}  
public void close() {  
this.isRun = false;  
}  
}
