java面向对象程序设计实验

A. java 面向对象设计 运用GUI技术的开发 进行小游戏程序的开发

/*原始图片分为16块第一块为空白

*我是这样想的：

*因为无法将图片分成15份而放到16块的区域中（至少是很难实现）

*因此将原世散始图片中一部分处理成白色，这样就好处理了

C. java程序设计 面向对象基础 实验

二。
1。People.java
public class People {

//性别（sex）及出生日期（date）；方法成员有：获取人的性别和出生日期及构造方法。要求构造方法可以设置性别和出生日期的初始值。
private int sex;
private Date birth;
public People (int sex, Date birth) {
this.sex = sex;
this.birth = birth;
}
public int getSex() {
return this.sex;
}
public Date getBirth() {
return this.birth;
}
}

2。Student.java
public class Student extends People{

private int sex;
private Date birth;
private String name;
private int stuno;
private double grate;
private String studentNative;

public Student(int sex, Date birth, String name, int stuno, double grate, String studentNative) {
super(sex, birth);
this.name = name;
this.stuno = stuno;
this.grate = grate;
this.studentNative = studentNative;
}

public Date getBirth() {
return birth;
}
public double getGrate() {
return grate;
}
public String getName() {
return name;
}
public int getSex() {
return sex;
}
public String getStudentNative() {
return studentNative;
}
public int getStuno() {
return stuno;
}
}

3。测试类自己编写就好了，创建一个People和Student的对象，然后设置值，取值就可以了。

五。
1.构造方法没有返回值，方法名和类名一样.
2.继承是指子类可以拥有父类的方法和属性；多态是指父类的引用可以指向子类对象的实例
3.重写
4.重载

其他的没什么了，自己完成以下吧。O(∩_∩)O~

D. java程序实验十一 面向对象 实验目的： 数组及集合的使用及实现； 要求： 掌握数组及集合操作的

packagecom;
