Thread.sleep()和Thread.currentThread().sleep()区别

先看一下代码

public class Thread1 extends Thread{

    @Override
    public void run() {
        try {
            System.out.println("Start");
            //Thread.sleep(5000);
            Thread.currentThread().sleep(5000);
            System.out.println("Finished");
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        Thread1 t1 = new Thread1();
        t1.start();
    

在编译器里运行看一下，没什么区别，但是在编程规范中，“调用一个实例的静态方法，而实际上应该是调用一个类的静态方法”，所以还是用Thread.sleep()最好
