final int N = 7; // number of boys，可改动

int x = 3;// some boy，可改动

int y = 5;// some girl，可改动

String result = "";// 记录结果，即第二个问题

// 初始化，假设队列存放男女生编号，从1开始

QueueInteger boys = new LinkedListInteger();

}

QueueInteger girls = new LinkedListInteger();

for (int i = 1; i = M; i++) {

}

// 跳舞开始

int min = boys.size() girls.size() ? girls.size() : boys.size();

int k = 1;// songs

int count = 2; // 求出两个值，可改动

while (k 1000) {//为了不死循环，这里假设最多有999支舞蹈

System.out.println("***This is the " + k + "st dance:");

for (int i = 0; i min; i++) {

// 跳舞，第一个问题：输出每曲配对情况

System.out.println("Boy " + boys.peek() + " = Girl "

+ girls.peek());

// 跳过的排到对尾

int boy = boys.remove();

boys.add(boy);

int girl = girls.remove();

girls.add(girl);

// 判断 x和y跳舞了没有

if (boy == x girl == y) {

result += k + ",";

count--;

}

}

if (count == 0)

break;

// next dance

k++;

}

// 结果

if (count == 0)

System.out.println("\n***Boy " + x + " and Girl " + y

+ " dance together in : " + result);//第二个问题的解答，跳了哪几支舞

else

System.out.println("\n***Boy " + x + " and Girl " + y

+ " have no chance to dance!");//第二个问题的解答，两人没机会跳舞

java中如何在窗体上插入一个随鼠标动眼睛的小人

我自己编了一个程序，有2个文件，我先说一下思路

用线程编程

监听鼠标移动事件，用线程不断获取鼠标坐标

根据鼠标坐标和眼球坐标来画出眼球的位置

package s0124随鼠标动眼睛;

//最初编写出问题的原因是没有明白把要做的事情放到run方法里面

import java.awt.BorderLayout;

import java.awt.Graphics;

import java.awt.event.MouseEvent;

import java.awt.event.MouseListener;

import java.awt.event.MouseMotionListener;

import javax.swing.JFrame;

import javax.swing.JPanel;

public class Main extends JFrame{

   static int xx;

static int yy;

JPanel drawpanel;

Graphics g;

public static void main(String[] args) {

Main a=new Main();

}

public Main()

{

this.setTitle("随着鼠标动眼睛");

this.setSize(500,500);

this.setLocationRelativeTo(null);       //设置窗体出现位置居中  

this.setDefaultCloseOperation(3);      //设置窗体的关闭操作

this.setResizable(false);                      //设置禁止调整窗体的大小                              

this.setLayout(new BorderLayout());            //设置为边框布局

drawpanel=new JPanel();                        //新建一个画图面板

this.add(drawpanel,BorderLayout.CENTER);       //将画图面板添加到窗体的中间位置     

this.setVisible(true);                         //设置窗体可见

g=drawpanel.getGraphics();                     //得到画图面板的画笔，为了传递给监听器listener

MyThread mt=new MyThread(g,drawpanel);         //新建一个监听器，并把参数传递进去

drawpanel.addMouseMotionListener(mt);          //为画图面板添加监听对象

Thread r=new Thread(mt);                     

r.start();                                //启动线程

}

}
