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);

Q1: java游戏编程-怪物跟着人移动问题
只需要让怪物得到当前人的坐标java人物移动代码，然后向这个方向移动就行java人物移动代码了。比如说java人物移动代码你可以用一个方向向量来代表怪物的运行状态，如：
class MoveDirection{
int dx;
int dy;
}
根据java人物移动代码你人物和怪物的相对位置，计算出dx,dy。比如说人物坐标是(300,300)，怪物坐标是(400,200)，怪物每次移动20。那么dx = -20, dy = 20。
然后你的怪物每次运动的时候增加方向向量就可以了。
class Monster{
public void move(MoveDirection direction){
this.x += direction.dx;
this.y += direction.dy;
}
}
如果你的人和怪物是在复杂的地图当中也是一样的。只不过要先判定是否可以向某个方向移动就行了。

Q5: Java 鼠标控制人物移动，地图随人物移动
去学习A星寻路，可以得到最短路径，其中也包括java人物移动代码了绕开障碍物java人物移动代码的代码，然后就是动画的图片切换了，如果说要地图跟随主角移动，那个应该是滚屏操作，也就是说java人物移动代码你主角往右走，超过窗口或者屏幕（全屏）坐标一半的时候，地图整个往左移动，速度和主角的一样就出来效果了。如果你看不懂A星的话，那咂就给你一段BFS的C++语言代码，自己转换成JAVA代码写法（就是改些关键字，有不少经典的游戏算法都来自C/C++）就可以了，这个是简化版的A星寻路，一样可以找到最近的路径，你把path 这个路径记录下来再换算成像素位置就可以得到行走的具体步伐了...
