二、Thread中的start和run的区别

1.调用run方法

public class ThreadTest {
    private static void attack() {
        System.out.println("Current Thread is : " + Thread.currentThread().getName());
    }

    public static void main(String[] args) throws InterruptedException {
        Thread t = new Thread(){
            @Override
            public void run() {
                attack();
            }
        };
        System.out.println("current main thread is : " + Thread.currentThread().getName());
        t.run();
    }

显示线程只有一个，即main线程

2.调用start方法

public class ThreadTest {
    private static void attack() {
        System.out.println("Current Thread is : " + Thread.currentThread().getName());
    }

    public static void main(String[] args) throws InterruptedException {
        Thread t = new Thread(() -> attack());
        System.out.println("current main thread is : " + Thread.currentThread().getName());
        t.start();
    }
}
