Example 1 of lambda expression

When we create a thread and start it, we can use the writing method of anonymous inner class ：

new Thread(new Runnable() {
    @Override
    public void run() {
        System.out.println(" You know what?   I'm better than you think   I want to be by your side ");
    }
}).start();

have access to Lambda Modify it in the format of . Revised as follows ：

new Thread(()->{
    System.out.println(" You know what?   I'm better than you think   I want to be by your side ");
}).start();
