java課程設計題目及代碼分別是：

1、題目：計算器。設計內容是設計一個圖形界面（GUI）的計算器應用程序，完成簡單的算術運算。

設計要求是設計的計算器應用程序可以完成家法、減法、乘法、除法和取余運算。且有小數點、正負號、求倒數、退格和清零功能。

2、代碼：

數字按鈕NumberButton類如下：

import java.awt.

import java.awt.event.

import javax.swing.

public class NumberButton extends Button.

{

int number.

public NumberButton(int number).

{

super(“”+number).

this.number=number.

setForeground(Color.blue).

}

public int getNumber().

{

return number;

}

其它java課程設計題目及代碼是：

題目：華容道。編寫一個按鈕的子類，使用該子類創建的對象代表華容道中的人物。通過焦點事件控制人物顏色，當人物獲得焦點時顏色為藍色，當失去焦點時顏色為灰色。

通過鍵盤事件和滑鼠事件來實現曹操、關羽等人物的移動。當人物上發生滑鼠事件或鍵盤事件時，如果滑鼠指針的位置是在人物的下方（也就是組件的下半部分）或按下鍵盤的「↓「鍵，該人物向下移動。向左、向右和向上的移動原理類似。

代碼是：

String name[]={“曹操”,”關羽”,”張”,”劉”,”馬”,”許”,”兵”,”兵”,”兵”,”兵”}.

for(int i=0;iname.length;i++).

{

person[i]=new Person(i,name[i]).

person[i].addKeyListener(this).

person[i].addMouseListener(this).

// person[i].addFocusListener(new Person).

add(person[i]).

}

person[0].setBounds(104,54,100,100).

person[1].setBounds(104,154,100,50).

person[2].setBounds(54,154,50,100).

person[3].setBounds(204,154,50,100).

person[4].setBounds(54,54,50,100).

person[5].setBounds(204,54,50,100);

person[6].setBounds(54,254,50,50);

person[7].setBounds(204,254,50,50);

person[8].setBounds(104,204,50,50);

person[9].setBounds(154,204,50,50);

我幫你編寫了一部分，實現了「輸入十個同學的相關信息，並在文本框中顯示」（圖形界面實現）。

要實現接下去的功能其實也真的不難的，但是真的很麻煩、很浪費時間……我就幫你做到這裡了，你自己添加一下代碼就可以（或者提高懸賞的話可以考慮考慮啊！哈哈……）代碼如下：

感覺不是特別麻煩。

文件系統是什麼？就是讀取個特殊文件嗎？要解碼？

界面建議你就用windowbuilder直接做吧，簡單點。

要看到結果，選擇題的好看，問題怎麼判斷。再來個論述題。

把要求寫詳細點。
