java线程创建的四种方式 - 面试宝典

javaCopy codepublic class MyThread extends Thread {
    @Override
    public void run() {
        // 线程执行的代码
    }
}
// 创建线程并启动
MyThread myThread = new MyThread();
myThread.start();

javaCopy codepublic class MyRunnable implements Runnable {
    @Override
    public void run() {
        // 线程执行的代码
    }
}
// 创建线程并启动
MyRunnable myRunnable = new MyRunnable();
Thread thread = new Thread(myRunnable);
thread.start();

javaCopy codepublic class MyCallable implements Callable<Integer> {
    @Override
    public Integer call() throws Exception {
        // 线程执行的代码
        return 1;
    }
}
// 创建线程并启动
MyCallable myCallable = new MyCallable();
ExecutorService executorService = Executors.newSingleThreadExecutor();
Future<Integer> future = executorService.submit(myCallable);

javaCopy codeRunnable myRunnable = new Runnable() {
    @Override
    public void run() {
        // 线程执行的代码
    }
};
// 创建线程池并执行任务
ExecutorService executorService = Executors.newFixedThreadPool(10);
executorService.execute(myRunnable);

javaCopy codeThread thread = new Thread() {
    @Override
    public void run() {
        // 线程执行的代码
    }
};
// 启动线程
thread.start();

javaCopy codeThread thread = new Thread(() -> {
    // 线程执行的代码
});
// 启动线程
thread.start();

javaCopy codeThreadFactory threadFactory = Executors.defaultThreadFactory();
Thread thread = threadFactory.newThread(() -> {
    // 线程执行的代码
});
// 启动线程
thread.start();
