下面代码大致想做到当主线程将toBeStop更新后所有线程将停止退出执行
import java.util.Arrays;
public class VolatileTest
{
volatile boolean toBeStop;
public static void main(String[] args)
{
VolatileTest test = new VolatileTest();
for(int i = 0 ; i<5;i++)
{
Thread t = test.new MyThread();
t.start();
}
while(Thread.activeCount()>1)
{
Thread[] active = new Thread[5];
System.out.println("还有线程在运行"+Thread.enumerate(active)+":["+Arrays.asList(active)+"]");
if(!test.toBeStop)
test.toBeStop = true;
}
}
class MyThread extends Thread
{
@Override
public void run()
{
int i = 0;
while(!toBeStop)
{
System.out.println(toBeStop+" "+this.getName()+":"+i++);
}
}
}
}
