P364实战练习第一题

ZuoyeThread类代码：

package zuoye;

public class ZuoyeThread extends Thread{

    public void run()
    {
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("大家好");
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("今天天气不错");
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("所以我决定去旅行");
    }
}

Test类代码：

package zuoye;

public class Thread1 {
    public static void main(String arg[])
    {
        ZuoyeThread t=new ZuoyeThread();
        t.start();
    }

}
