使用线程池方式创建子线程

public static void main(String[] args) {
        ExecutorService executorService = Executors.newCachedThreadPool();
        executorService.execute(new Runnable() {
            @Override
            public void run() {
                System.out.println(Thread.currentThread().getName()+"-我是子线程");
            }
        });


    }

 

lambda表达式方式

 public static void main(String[] args) {
        ExecutorService executorService = Executors.newCachedThreadPool();
        executorService.execute(() -> System.out.println(Thread.currentThread().getName()+"-我是子线程"));
    }
