以下实例演示了如何使用interrupt()方法来中断线程并使用 isinterrupted() 方法来判断线程是否已中断：

public class main extends object
implements runnable {
public void run() {
try {
system.out.println("in run() - 将运行 work2() 方法");
work2();
system.out.println("in run() - 从 work2() 方法回来");
}
catch (interruptedexception x) {
system.out.println("in run() - 中断 work2() 方法");
return;
}
system.out.println("in run() - 休眠后执行");
system.out.println("in run() - 正常离开");
}
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() - 中断其他线程");
t.interrupt();
system.out.println("in main() - 离开");
}
}
以上代码运行输出结果为：
in run() - 将运行 work2() 方法
in main() - 中断其他线程
in main() - 离开
c isinterrupted()=true
in run() - 中断 work2() 方法
以上就是java 实例 - 中断线程的内容。
