java中断
InterruptDemo.classpackage com.jdk.api.demo;
枷锁时，io 中断不起作用。
中断只对wait sleep 等函数起作用
public class InterruptDemo {
public static void main(String[] args) throws InterruptedException{
Thread run = new Thread(new RunClass0());
run.start();
System.out.println("isDaemon:"+run.isDaemon());
Thread.sleep(10000);
run.interrupt();
System.out.println("isDaemon:"+run.isDaemon()+"--1--"+run.isInterrupted());
//run.isInterrupted() 不会取消终端状态
}
}
/**
* 根本不会理会run.interrupt();的中断,代码会一直运行下去
* @author aircoder
*
*/
class RunClass implements Runnable{
@Override
public void run() {
longi=0;
while(true){
if(i==1000000000){
System.out.println("I'm still alive!");
i = 0;
System.out.println("--1--"+Thread.interrupted());//会取消中断的标志
}
else{
i++;
}
}
}
}
/**
*run.interrupt(); 执行后代码就会结束
* @author aircoder

*/
class RunClass0 implements Runnable{
@Override
public void run() {
longi=0;
while(true && !Thread.currentThread().isInterrupted()){//检查代码是否发生了中断
if(i==1000000000){
System.out.println("I'm still alive!");
i = 0;
}
else{
i++;
}
}
}
}
