Java如何中斷正在運行的線程？

在Java編程中，如何中斷正在運行的線程？

以下示例演示如何使用Thread類的interrupt()方法中斷正在運行線程，並檢查線程是否使用isInterrupted()方法中斷。

package com.yiibai; public class InterruptThread extends Object implements Runnable { public void run() { try { System.out.println("in run() - about to work2()"); work2(); System.out.println("in run() - back from work2()"); } catch (InterruptedException x) { System.out.println("in run() - interrupted in work2()"); return; } System.out.println("in run() - doing stuff after nap"); System.out.println("in run() - leaving normally"); } public void work2() throws InterruptedException { while (true) { if (Thread.currentThread().isInterrupted()) { System.out.println("C isInterrupted()=" + Thread.currentThread().isInterrupted()); Thread.sleep(2000); System.out.println("D isInterrupted()=" + Thread.currentThread().isInterrupted()); } } } public void work() throws InterruptedException { while (true) { for (int i = 0; i < 100000; i++) { int j = i * 2; } System.out.println("A isInterrupted()=" + Thread.currentThread().isInterrupted()); if (Thread.interrupted()) { System.out.println("B isInterrupted()=" + Thread.currentThread().isInterrupted()); throw new InterruptedException(); } } } public static void main(String[] args) { InterruptThread si = new InterruptThread(); Thread t = new Thread(si); t.start(); try { Thread.sleep(2000); } catch (InterruptedException x) { } System.out.println("in main() - interrupting other thread"); t.interrupt(); System.out.println("in main() - leaving"); } } 

Java

上述代碼示例將產生以下結果 -

in run() - about to work2()
in main() - interrupting other thread
in main() - leaving
C isInterrupted()=true
in run() - interrupted in work2()
