Java做一个简单的宠物商店，实现添加，购买，结算等功能

如今即将上大二的我，回头做了一下大一上半学期的宠物商店的一个小项目，那时候刚接触java就被要求做个这东西出来，当时做了真的特别久。现在做起来觉得自己进步不少，挺简单的。废话不多说，直接上代码，嘿嘿。

整个程序主要用到ArrayList集合，对ArrayList进行增删查改。

1.先写一个属性类

package com.animalShop; public class property { private String name; private String kind; private int age; private double price; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getKind() { return kind; } public void setKind(String kind) { this.kind = kind; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public property(String name, String kind, int age, double price) { this.name = name; this.kind = kind; this.age = age; this.price = price; } @Override public String toString() { return name + "t" + kind + "t" + age + "t" + price; } }

package com.animalShop; import java.util.ArrayList; import java.util.Scanner; public class shop { //商店品种集合 ArrayList<property> amlList = new ArrayList<>(); //购物车集合 ArrayList<property> stoCarList = new ArrayList<>(); //添加宠物到商店的方法 public void addAml() { System.out.println("请输入添加的宠物信息(名字->种类->年龄->价格):"); //创建对象animal属性,键入animal property pty = new property(getString(), getString(), getInt(), getDouble()); //判断是否添加到amlList集合里面 boolean bool = amlList.add(pty); if (bool == true) { System.out.println("添加成功!"); } else { System.out.println("添加失败!"); } } //显示宠物商店宠物方法 public void showAml() { boolean bool = amlList.isEmpty(); if (bool != true) { System.out.println("序号" + "t" + "名字" + "t" + "种类" + "t" + "年龄" + "t" + "价格"); //定义一个序号 int n = 1; //遍历出宠物商店宠物 for (property property : amlList) { System.out.println(n + "t" + property); n++; } System.out.println(" "); } else { System.out.println("商店维护中，暂时没有商品哦！"); System.out.println(" "); } } //购买宠物到购物车的方法 public void buyAml() { boolean bool = amlList.isEmpty(); if (bool != true) { System.out.print("请输入您想要购买的宠物的序号:"); //键入购买宠物的序号 int n = getInt(); //防止下标越界 if (n <= amlList.size()) { stoCarList.add(amlList.get((n - 1))); amlList.remove((n - 1)); System.out.println("购买成功！"); System.out.println(" "); } else { System.out.println("购买失败！"); System.out.println("您想要的宠物不存在，请核实商店现有的宠物！"); System.out.println(" "); } } else { System.out.println("商店维护中，暂时没有商品可以购买哦！"); System.out.println(" "); } } //查看购物车方法 public void showShopCar() { boolean bool = stoCarList.isEmpty(); if (bool != true) { System.out.println("-------购物车-------"); System.out.println("序号" + "t" + "名字" + "t" + "种类" + "t" + "年龄" + "t" + "价格"); shopList(); System.out.println(" "); } else { System.out.println("您还没有购买过宠物呢！"); System.out.println(" "); } } //购物车结算方法 public void totalPrice() { boolean bool =stoCarList.isEmpty(); if (bool != true) { System.out.println("-------清单-------"); System.out.println("序号" + "名字" + "t" + "种类" + "t" + "年龄" + "t" + "价格" + "t"); shopList(); //清空购物车 stoCarList.clear(); //判断购物车是否为空 if (stoCarList.isEmpty()) { System.out.println("结算成功！"); System.out.println(" "); } else { System.out.println("结算失败！"); System.out.println(" "); } }else { System.out.println("购物车没有任何宠物哦，请先购买再结算！"); System.out.println(" "); } } //删除购物车某一个宠物方法 public void delStoreCar() { boolean bool = stoCarList.isEmpty(); if (bool != true) { System.out.print("请输入购物车中要删除的宠物序号："); int n = getInt(); //防止下标越界 if ((n - 1) <= stoCarList.size()) { stoCarList.remove((n - 1)); System.out.println("删除成功!"); System.out.println(" "); } else { System.out.println("删除失败！"); System.out.println("请检查购物车宠物是否存在!"); System.out.println(" "); } } else { System.out.println("您还没有购买过宠物，无需删除！"); System.out.println(" "); } } //删除商店某一个宠物 public void delAmlList() { boolean bool = amlList.isEmpty(); if (bool != true) { System.out.print("请输入商店中要删除的宠物序号："); int n = getInt(); //防止下标越界 if ((n - 1) <= amlList.size()) { amlList.remove((n - 1)); System.out.println("删除成功!"); System.out.println(" "); } else { System.out.println("删除失败!"); System.out.println("请检查商店宠物是否存在!"); System.out.println(" "); } } else { System.out.println("商城还未上架过任何宠物！"); System.out.println(" "); } } public static void main(String[] args) { Scanner sc = new Scanner(System.in); shop shop = new shop(); while (true) { System.out.println("--------欢" + "t" + "迎" + "t" + "来" + "t" + "到" + "t" + "上" + "t" + "天" + "t" + "的" + "t" + "小" + "t" + "宝" + "t" + "贝" + "t" + "儿" + "t" + "宠" + "t" + "物" + "t" + "商" + "t" + "店--------"); System.out.println("请输入序号(1：上架宠物 2：下架宠物 3：打开商城 4：购买 5：打开购物车 6：删除购物车宠物 7：结算 8：离开)"); switch (sc.nextInt()) { case 1: shop.addAml(); break; case 2: shop.delAmlList(); break; case 3: shop.showAml(); break; case 4: shop.buyAml(); break; case 5: shop.showShopCar(); break; case 6: shop.delStoreCar(); break; case 7: shop.totalPrice(); break; case 8: System.out.println("再见！"); return; } } } //封装购物清单方法，提高代码的复用性 public void shopList() { double total = 0; //序号计数器 int n = 1; //遍历购物车 for (int i = 0; i < stoCarList.size(); i++) { System.out.println(n + "t" + stoCarList.get(i)); property price = stoCarList.get(i); total += price.getPrice(); n++; } System.out.println("总价：" + "t" + "t" + "t" + total); } /* * 这里没有创建一个对象键入，是因为创建一个对象，在键入数据时，会因为对象数据类型冲突，导致InputMismatchException异常 * */ public static String getString() { Scanner a = new Scanner(System.in); return a.next(); } public static int getInt() { Scanner b = new Scanner(System.in); return b.nextInt(); } public static double getDouble() { Scanner c = new Scanner(System.in); return c.nextDouble(); } }
