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;  }  }
