java线程的一个小例子

最近复习了一下java的线程，做个笔记。

package com.lee;

import java.io.IOException;
import java.nio.CharBuffer;

public class ThreadTest {

    int i = 0;
    int j=0;

    public static void main(String[] args) {

        // TODO Auto-generated method stub

        ThreadTest t = new ThreadTest();

        t.runTest();

    }

    public void runTest() {
        new Thread(new Runnable() {//创建线程  new Runnable接口
            @Override
            public void run() {//重写run方法
                // TODO Auto-generated method stub
                while (true) {
                    System.out.println("呵呵  " + i);
                    i++;
                    if(i>15)
                        break;
                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }
        }).start();//启动线程
        new Thread(new Runnable() {
            @Override
            public void run() {
                // TODO Auto-generated method stub
                while (true) {
                    System.out.println("lalallala  " + j);
                    j++;
                    if (j>15) {
                        break;
                    }
                    try {
                        Thread.sleep(600);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }
        }).start();
    }
}
