Question

Java定义一个表示人民币的类Money，

1定义整形成员变量yuan,jiao,fen,分别表示元角分。

2构造方法，利用实数表示的金额初始化成员yuan,jiao,fen
3void show()方法按XX元XX角XX分格式输出
4在主方法中，接受一个实数输入，创建Money对象，再调用show()方法输出。

Answer 1

public class Money {
private int yuan;
private int jiao;
private int fen;

public Money(int yuan,int jiao, int fen){
this.yuan=yuan;
this.jiao=jiao;
this.fen=fen;

}

public void show(){

System.out.printf("%d元%d角%d分",yuan,jiao,fen);

}

public static void main(String[] args) {
Money m=new Money(4,5,6);
m.show();

}

}

Answer 2

money实体类:
public class Money {//1 定义整形成员变量yuan,jiao,fen

private int yuan;
private int jiao;
private int fen;
public Money(int yuan,int jiao,int fen){//2 构造方法，初始化成员yuan,jiao,fen

this.yuan = yuan;
this.jiao = jiao;
this.fen = fen;
}
public int getYuan() {
return yuan;
}
public void setYuan(int yuan) {
this.yuan = yuan;
}
public int getJiao() {
return jiao;
}
public void setJiao(int jiao) {
this.jiao = jiao;
}
public int getFen() {
return fen;
}
public void setFen(int fen) {
this.fen = fen;
}
}
入口点/主方法：
public class MoneyShow {

public void show(Money money){//3 void show()方法按XX元XX角XX分格式输出

System.out.println(money.getYuan()+"元"+money.getJiao()+"角"+money.getFen()+"分");
}
public static void main(String[] args) {
int yuan = 10,jiao = 5,fen = 3;
Money money = new Money(yuan,jiao,fen);//4 创建Money对象，再调用show()方法输出

MoneyShow ms = new MoneyShow();
ms.show(money);
}
}
