Sleep停止線程:

 

在Sleep狀態下被interrupt，interrupted 狀態會被擦除，返回false。

線程在Sleep狀態下被interrupt：

public class SleepInterruptThread extends Thread{    @Override    public void run() {        try {            System.out.println("run begin");            Thread.sleep(2000000);            System.out.println("run end");        } catch (InterruptedException e) {            System.out.println("Interrupt in sleep stage. Interrupted status: " + this.isInterrupted());            e.printStackTrace();        }    }}public class ThreadRunMain {    public static void main(String[] args) {        testSleepInterruptThread();    }    public static void testSleepInterruptThread(){        try {            SleepInterruptThread sit = new SleepInterruptThread();            sit.start();            Thread.sleep(1000);            sit.interrupt();        } catch (InterruptedException e) {            System.out.println("Main catch");            e.printStackTrace();        }        System.out.println("end!");    }}

運行結果：

 

線程在Sleep之前被interrupt：

public class BeforeSleepInterruptThread extends Thread{    @Override    public void run() {        try {            for (int i=0;i<100000;i++){                System.out.println("i="+(i+1));            }            System.out.println("run begin");            Thread.sleep(2000000);            System.out.println("run end");        } catch (InterruptedException e) {            System.out.println("First interrupt, then sleep. Interrupted status: " + this.isInterrupted());            System.out.println("First interrupt, then sleep. Interrupted status: " + Thread.interrupted());            e.printStackTrace();        }    }}public class ThreadRunMain {    public static void main(String[] args) {        testBeforeSleepInterruptThread();    }    public static void testBeforeSleepInterruptThread(){        try {            BeforeSleepInterruptThread bsit = new BeforeSleepInterruptThread();            bsit.start();            Thread.sleep(100);            bsit.interrupt();            System.out.println("end!");        } catch (InterruptedException e) {            e.printStackTrace();        }    }}
