java课程设计题目及代码是什么？
java课程设计题目及代码分别是：
1、题目：计算器。设计内容是设计一个图形界面（GUI）的计算器应用程序，完成简单的算术运算。
设计要求是设计的计算器应用程序可以完成家法、减法、乘法、除法和取余运算。且有小数点、正负号、求倒数、退格和清零功能。
2、代码：
数字按钮NumberButton类如下：
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课程设计题目及代码是：
题目：华容道。编写一个按钮的子类，使用该子类创建的对象代表华容道中的人物。通过焦点事件控制人物颜色，当人物获得焦点时颜色为蓝色，当失去焦点时颜色为灰色。
通过键盘事件和鼠标事件来实现曹操、关羽等人物的移动。当人物上发生鼠标事件或键盘事件时，如果鼠标指针的位置是在人物的下方（也就是组件的下半部分）或按下键盘的“↓“键，该人物向下移动。向左、向右和向上的移动原理类似。
代码是：
String name[]={"曹操","关羽","张","刘","马","许","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);

Java课程设计
感觉不是特别麻烦。
文件系统是什么？就是读取个特殊文件吗？要解码？
界面建议你就用windowbuilder直接做吧，简单点。
要看到结果，选择题的好看，问题怎么判断。再来个论述题。
把要求写详细点。
