Java如何停止线程?
在Java编程中,如何停止线程?
以下示例演示了如何通过创建一个用户定义的方法run()
方法和Timer
类来停止线程。
package com.yiibai;
import java.util.Timer;
import java.util.TimerTask;
class CanStop extends Thread {
private volatile boolean stop = false;
private int counter = 0;
public void run() {
while (!stop && counter < 10000) {
//System.out.println(counter++);
}
if (stop){
System.out.println("Detected stop");
}
}
public void requestStop() {
stop = true;
}
}
public class StoppingThread {
public static void main(String[] args) {
final CanStop stoppable = new CanStop();
stoppable.start();
new Timer(true).schedule(new TimerTask() {
public void run() {
System.out.println("Requesting stop");
stoppable.requestStop();
}
}, 350);
}
}
上述代码示例将产生以下结果 -
Requesting stop
Detected stop
