1. 设置标志位(无法处理线程阻塞时的问题);
2. 调用Thread类提供的stop
方法强行关闭线程;
3. 通过Thread类提供的interrupt
方法
举例:设置标志位
class InterruptThread extends Thread{ private boolean flag = true; public void setFlag(boolean flag) { this.flag = flag; } @Override public void run() { int i =0; while(flag){ i++; System.out.println(Thread.currentThread().getName()+",i= "+i); } } } public class TestInterrupt { public static void main(String[] args) throws InterruptedException { InterruptThread t1 = new InterruptThread(); t1.start(); //子线程和主线程并发执行,为了看到效果,休眠1s Thread.sleep(1000); t1.setFlag(false
