如何在给定点停止线程？

public class StopThreadExample {
    public static void main(String[] args) {
        // 创建一个线程
        Thread thread = new Thread(() -> {
            for (int i = 0; i < 100; i++) {
                System.out.println("执行任务：" + i);
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                if (i == 50) {
                    // 在给定点停止线程
                    Thread.currentThread().interrupt();
                }
            }
        });

        // 启动线程
        thread.start();

        // 等待线程结束
        try {
            thread.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println("线程已停止");
    }
}
