Java 實例 - 中斷線程
Java 實例以下實例演示了如何使用interrupt()方法來中斷線程並使用 isInterrupted() 方法來判斷線程是否已中斷：
Main.java 檔
public class Main extends Object
implements Runnable {
public void run() {
try {
System.out.println("in run() - 將運行 work2() 方法");
work2();
System.out.println("in run() - 從 work2() 方法回來");
}
catch (InterruptedException x) {
System.out.println("in run() - 中斷 work2() 方法");
return;
}
System.out.println("in run() - 休眠後執行");
System.out.println("in run() - 正常離開");
}
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) {
Main si = new Main();
Thread t = new Thread(si);
t.start();
try {
Thread.sleep(2000);
}
catch (InterruptedException x) {
}
System.out.println("in main() - 中斷其他線程");
t.interrupt();
System.out.println("in main() - 離開");
}
}
以上代碼運行輸出結果為：
in run() - 將運行 work2() 方法 in main() - 中斷其他線程 in main() - 離開 C isInterrupted()=true in run() - 中斷 work2() 方法
