java 判断某个方法执行是否超时
想在java程序中判断某个方法执行是否超时，比如说，如果该方法执行时间超过两秒，那么将结束本次程序执行
public class TimeoutException extends RuntimeException {
/**
* 序列化号
*/
private static final long serialVersionUID = -8078853655388692688L;

public TimeoutException(String errMessage)
{
super(errMessage);
System.out.println("2");
}


}

public class TimeoutThread extends Thread{
/**
* 计时器超时时间
*/
private long timeout;
  
/**
* 计时是否被取消
*/
private boolean isCanceled = false;
  
/**
* 当计时器超时时抛出的异常
*/
private TimeoutException timeoutException;
  
/**
* 构造器
* @param timeout 指定超时的时间
*/
public TimeoutThread(long timeout,TimeoutException timeoutErr) {
super();
this.timeout = timeout;
this.timeoutException = timeoutErr;
//设置本线程为守护线程
this.setDaemon(true);
}
  
/**
* 取消计时
*/
public synchronized void cancel()
{
isCanceled = true;
}

/**
* 启动超时计时器
*/
public void run()  
{
try {
System.out.println("run()");
Thread.sleep(timeout);
System.out.println("sleep");
if(!isCanceled) throw timeoutException;
} catch (InterruptedException e) {
System.out.println("eeeeeeeeee");
e.printStackTrace();
throw timeoutException;
}  
}

}

public class MainCheck {

/**
* @param args
*/
public static void main(String[] args) {

//初始化超时类
System.out.println("main");
TimeoutThread t = new TimeoutThread(1000,new TimeoutException("超时"));
System.out.println("t");
try{
System.out.println("t.start()-begin");
t.start();
System.out.println("t.start()-end");
//.....要检测超时的程序段....
getMothod();
t.cancel();
System.out.println("t.fail="+t.isfail);
System.out.println("t.cancel()-end");
}catch (Exception e)
{
按道理讲应该这里可以捕获到这个异常，可是怎么都进不来
System.out.println("eeeeeeeeeeeee");
//...对超时的处理...

}
System.out.println("main==end");
}
public static void getMothod(){
while(true){

}
}

}
