完成所有线程，即使其中一个抛出异常

Thread thread1 = new Thread(() -> {
    try {
        // 线程1的任务
    } catch (Exception e) {
        // 处理线程1的异常
    }
});

Thread thread2 = new Thread(() -> {
    try {
        // 线程2的任务
    } catch (Exception e) {
        // 处理线程2的异常
    }
});

// 启动线程
thread1.start();
thread2.start();

ExecutorService executorService = Executors.newFixedThreadPool(2);

Future<?> future1 = executorService.submit(() -> {
    // 线程1的任务
});

Future<?> future2 = executorService.submit(() -> {
    // 线程2的任务
});

// 关闭线程池
executorService.shutdown();

CountDownLatch latch = new CountDownLatch(2);

Thread thread1 = new Thread(() -> {
    try {
        // 线程1的任务
    } catch (Exception e) {
        // 处理线程1的异常
    } finally {
        latch.countDown();
    }
});

Thread thread2 = new Thread(() -> {
    try {
        // 线程2的任务
    } catch (Exception e) {
        // 处理线程2的异常
    } finally {
        latch.countDown();
    }
});

// 启动线程
thread1.start();
thread2.start();

// 等待所有线程执行完成
latch.await();
