package com;

public class Demo {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        //方法1
        Thread t = new Thread() {
            public void run() {
                for (int i = 1; i <= 5; i++) {
                    System.out.print(i + " ");
                }
            }
        };
        t.start();
        System.out.print("\r\n");
        //方法2

        Runnable r = new Runnable() {
            public void run() {
                for (int i = 1; i <= 5; i++) {
                    System.out.print(i + " ");
                }
            }
