1、Timer

public class test06 {
    public static void main(String[] args) throws InterruptedException {
        Timer timer = new Timer();
        TimerTask timerTask = new TimerTask(){

                    try {Thread.sleep(100);} catch (InterruptedException e) {e.printStackTrace();}
                    System.out.println("线程名1："+Thread.currentThread().getName());
                }
            }
        };
