class Goods {
double unitPrice;//单价
double account;//数量
Goods(double unitPrice, double account){
this.unitPrice = unitPrice;
this.account = account;
}
double totalPrice(){//计算总价
return unitPrice*account;
}
void show(){
System.out.println("单价："+unitPrice);
System.out.println("购买数量："+account);
System.out.println("购买商品的总金额："+this.totalPrice());
}
}
class Clothing extends Goods{
String style;//样式
Clothing(String style, double unitPrice, double account) {
super(unitPrice, account);
this.style = style;
}
void show(){
System.out.println("衣服单价："+unitPrice);
System.out.println("衣服数量："+account);
System.out.println("衣服总金额："+this.totalPrice());
}
void showClothing(){
System.out.println("衣服样式："+style);
this.show();
}
}
public class Prog1{
public static void main(String[] args) {
Clothing clothing = new Clothing("蓝色风衣",100,2);
