java面向對象程序設計實驗

A. java 面向對象設計 運用GUI技術的開發 進行小游戲程序的開發

/*原始圖片分為16塊第一塊為空白

*我是這樣想的：

*因為無法將圖片分成15份而放到16塊的區域中（至少是很難實現）

*因此將原世散始圖片中一部分處理成白色，這樣就好處理了

C. java程序設計 面向對象基礎 實驗

二。
1。People.java
public class People {

//性別（sex）及出生日期（date）；方法成員有：獲取人的性別和出生日期及構造方法。要求構造方法可以設置性別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。測試類自己編寫就好了，創建一個People和Student的對象，然後設置值，取值就可以了。

五。
1.構造方法沒有返回值，方法名和類名一樣.
2.繼承是指子類可以擁有父類的方法和屬性；多態是指父類的引用可以指向子類對象的實例
3.重寫
4.重載

其他的沒什麼了，自己完成以下吧。O(∩_∩)O~

D. java程序實驗十一 面向對象 實驗目的： 數組及集合的使用及實現； 要求： 掌握數組及集合操作的
