Posted by: ik9099 Posted on: 2004-08-06 14:47 我是一个JAVA的初学者,想请教各位前辈一个非常简单的问题,怎么能用3个线程分别打印出5,7,9的1-5的倍数.请多多指教

程序写的有点长了，因为是新手，没做到代码复用，不过能实现功能。

public class ThreadTest1{
  public static void main(String[] args){
    Go1 g1 = new Go1();
    Thread a1 = new Thread(g1);
    a1.start();

    Go2 g2 = new Go2();
    Thread a2 = new Thread(g2);
    a2.start();

    Go3 g3 = new Go3();
    Thread a3 = new Thread(g3);
    a3.start();

  }
}

class Go1 implements Runnable{
  public void run(){
    for(int i=1;i<6;i++){
      int k = 5 ;
      k *= i;
      System.out.println("5的" + i +"倍是 : "+ k);
    }
  }
}

class Go2 implements Runnable{
  public void run(){
    for(int i=1;i<6;i++){
      int k = 7 ;
      k *= i;
      System.out.println("7的" + i +"倍是 : "+ k);
    }
  }
}

class Go3 implements Runnable{
  public void run(){
    for(int i=1;i<6;i++){
      int k = 9 ;
      k *= i;
      System.out.println("9的" + i +"倍是 : "+ k);
    }
  }
}

我也写一个
public class Test{
public static void main(String args[]){
MyThread t5 = new MyThread(5);
MyThread t7 = new MyThread(7);
MyThread t9 = new MyThread(9);
t5.start();
t7.start();
t9.start();
}
}
class MyThread extends Thread{
private int input;
public MyThread(int i){
input = i;
}
public void run(){
for(int i = 1; i < 6; i++){
System.out.println(input + "的" + i + "倍是：" + (i * input));
}
}
}

我的改进版的，和上面的老兄的差不多了！

public class ThreadTest1_2{
  public static void main(String[] args){
    new Go(5).start();
    new Go(7).start();
    new Go(9).start();
  }
}

class Go extends Thread{
  private int a;
  Go(int i){
    a = i;
  }

  public void run(){
    int k = a;
    for(int i=1;i<6;i++){
      a =k * i;
      System.out.println(k +" 的 " + i +" 倍是 "+ a);
    }
  }
}
