Java oop 的题与答案6：使用程序模拟英雄金币数，get与set知识，访问修饰符（有图）
//使用程序模拟英雄金币数，使用构造函数设置默认值为300，设置set方法可以给每个用户增进金币，
//get获取每个用户的金币数，定义静态变量统计总金币数，创建5个对象，并赋值，
//保存到数组了，求总金币和平均金币
package a;
public class student // public可不写，不写就有默认的修饰访问符
{
public static void main(String[] args) {
student[] stdAry = new student[5];
stdAry[0] = new student("张三", 80);
stdAry[1] = new student("李 四", 70);
stdAry[2] = new student("王 五", 60);
stdAry[3] = new student("王 三", 60);
stdAry[4] = new student("王 四", 60);
for (int i = 0; i < stdAry.length; i++) {
renshu++;
}
System.out.println("总金币为" + student.jinBiShuzs);
System.out.println("平均金币为" + student.jinBiShuzs / renshu);
}
private static int zongchengji;
private static int jinBiShu = 300;// 金币数
private static int jinBiShuzs = 0;
private static int renshu = 0;
private String name;// 姓名
private static int getZongchengji() {
return zongchengji;
}
public static void setZongchengji(int zongchengji) {
student.zongchengji = zongchengji;
}
public static int getJinBiShu() {
return jinBiShu;
}
public static void setJinBiShu(int jinBiShu) {
student.jinBiShu = jinBiShu;
}
public static int getJinBiShuzs() {
return jinBiShuzs;
}
public static void setJinBiShuzs(int jinBiShuzs) {
student.jinBiShuzs = jinBiShuzs;
}
public static int getRenshu() {
return renshu;
}
public static void setRenshu(int renshu) {
student.renshu = renshu;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public student(String name, int jinBiShu) {
jinBiShuzs = jinBiShuzs + jinBiShu+300;
this.name = name;
this.jinBiShu = jinBiShu;// 在构造方法里进行赋值
System.out.println("姓名为" + name);
}
}
运行效果：
get与set知识：
访问修饰符：
