本文实例为大家了java实现超市管理系统的具体代码，供大家参考，具体内容如下
使用选择结构，循环结构，数组的知识实现一个超市管理系统
import java.util.Arrays;public class Goods {private int id;private double price;private String name;public Goods(int id, double price, String name) {this.id = id;this.price = price;this.name = name;}public int getId {return id;}public void setId(int id) {this.id = id;}public double getPrice {return price;}public void setPrice(double price) {this.price = price;}public String getName {return name;}public void setName(String name) {this.name = name;}public Goods //增加商品public Goods add(Goodsgoods,Goods newGood){goods= Arrays.copyOf(goods,goods.length+1);goods[goods.length-1]=newGood;return goods;}//删除商品public static Goods del(Goodsgoods,int id){int i=0;while(true){if(goods[i].getId==id){goods[i]=null;return goods;}i++;if(i>=goods.length){return goods;}}}//添加商品public static Goods change(Goodsgoods,int id,int newId,double newPrice,String newName){int i=0;while (true){if(goods[i].getId==id){goods[i].setId(newId);goods[i].setPrice(newPrice);goods[i].setName(newName);return goods;}i++;if(i>=goods.length){return goods;
