// 跳舞開始

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

int k = 1;// songs

int count = 2; // 求出兩個值，可改動

while (k 1000) {//為了不死循環，這里假設最多有999支舞蹈

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

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

// 跳舞，第一個問題：輸出每曲配對情況

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

+ girls.peek());

// 跳過的排到對尾

int boy = boys.remove();

boys.add(boy);

int girl = girls.remove();

girls.add(girl);

// 判斷 x和y跳舞了沒有

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

result += k + ",";

count--;

}

}

if (count == 0)

break;

// next dance

k++;

}

// 結果

if (count == 0)

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

+ " dance together in : " + result);//第二個問題的解答，跳了哪幾支舞

else

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

+ " have no chance to dance!");//第二個問題的解答，兩人沒機會跳舞

java中如何在窗體上插入一個隨鼠標動眼睛的小人

我自己編了一個程序，有2個文件，我先說一下思路

用線程編程

監聽鼠標移動事件，用線程不斷獲取鼠標坐標

根據鼠標坐標和眼球坐標來畫出眼球的位置

package?s0124隨鼠標動眼睛;

//最初編寫出問題的原因是沒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;

public?static?void?main(String[]?args)?{

Main?a=new?Main();

}

public?Main()

{

this.setTitle("隨著鼠標動眼睛");

this.setSize(500,500);

this.setLocationRelativeTo(null);??? ???//設置窗體出現位置居中 ?

this.setDefaultCloseOperation(3);?? ???//設置窗體的關閉操作

this.setResizable(false);??????????????????????//設置禁止調整窗體的大小??????????????????????????????

this.setLayout(new?BorderLayout());????????????//設置為邊框布局

drawpanel=new?JPanel();????????????????????????//新建一個畫圖面板

this.add(drawpanel,BorderLayout.CENTER);???????//將畫圖面板添加到窗體的中間位置?????

this.setVisible(true);?????????????????????????//設置窗體可見

g=drawpanel.getGraphics();?????????????????????//得到畫圖面板的畫筆，為了傳遞給監聽器listener

MyThread?mt=new?MyThread(g,drawpanel);?????????//新建一個監聽器，并把參數傳遞進去

drawpanel.addMouseMotionListener(mt);??????????//為畫圖面板添加監聽對象

Thread?r=new?Thread(mt);?????????????????????

r.start(); ???????????????????????????????//啟動線程
