这篇文章给大家分享的是有关如何使用Java实现商品的查找、添加、出库、入库操作的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

具体如下：

package com.jredu.oopch08;public class Goods1 { private int id; private String name; private double price; private String uom; private int balance; public Goods1(int id, String name, double price, String uom, int balance) { super(); this.id = id; this.name = name; this.price = price; this.uom = uom; this.balance = balance; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } public String getUom() { return uom; } public void setUom(String uom) { this.uom = uom; } public int getBalance() { return balance; } public void setBalance(int balance) { this.balance = balance; }}package com.jredu.oopch08;import java.util.HashMap;import java.util.Iterator;import java.util.Map;import java.util.Scanner;import java.util.Set;public class TestGoods1 { private static Map map = new HashMap(); private static Scanner in = new Scanner(System.in); public static void get() { Goods1 goods1 = new Goods1(1001, "脉动水蜜桃 ", 7.0, "1.5l", 50); Goods1 goods2 = new Goods1(1002, "桃李熟切片 ", 6.5, "400g", 10); Goods1 goods3 = new Goods1(1003, "吉白芝麻油 ", 9.5, "125ml", 20); Goods1 goods4 = new Goods1(1004, "雀巢奶咖啡", 1.5, "13g", 200); Goods1 goods5 = new Goods1(1005, "白玉黄豆芽 ", 2.4, "350g", 50); map.put(goods1.getId(), goods1); map.put(goods2.getId(), goods2); map.put(goods3.getId(), goods3); map.put(goods4.getId(), goods4); map.put(goods5.getId(), goods5); } public static boolean check(int id) { // 检测匹配id if (!map.containsKey(id)) { // 没有匹配id return false; } else { // 有匹配的id return true; } } public static void add() {// 新增商品 System.out.println(">>新增商品"); System.out.print("请输入商品编号："); int id = in.nextInt(); if (new TestGoods1().check(id)) { // 有匹配的id System.out.println("对不起，此商品已存在!"); } else { System.out.print("请输入商品名称："); String name = in.next(); System.out.print("请输入商品单价："); double price = in.nextDouble(); System.out.print("请输入商品单位："); String uom = in.next(); System.out.print("请输入商品库存："); int balance = in.nextInt(); Goods1 goods6 = new Goods1(id, name, price, uom, balance); map.put(goods6.getId(), goods6); System.out.println("新增成功!"); } } public static void show() {// 显示商品信息 System.out.println("商品编号\t商品名称\t\t商品单价\t单位\t数量"); Set entrySet = map.entrySet(); Iterator iter = entrySet.iterator(); while (iter.hasNext()) { Map.Entry entry = iter.next(); System.out.print(entry.getKey() + "\t"); System.out.println(entry.getValue().getName() + "\t\t" + entry.getValue().getPrice() + "\t" + entry.getValue().getUom() + "\t" + entry.getValue().getBalance()); } } public static void inStore() {// 入库 System.out.println(">>商品入库"); System.out.print("请输入商品编号："); int id = in.nextInt(); for (int i = 0; i

< map.size(); i++) { if (new TestGoods1().check(id)) { //有匹配的id System.out.print("请输入入库数量："); int count = in.nextInt(); int c = ((Goods1) map.get(id)).getBalance()+count; ((Goods1) map.get(id)).setBalance(c); break; }else{ //没有匹配的id System.out.println("对不起，此商品不存在！"); break; } } } public void outStore() {// 出库 System.out.println(">

((Goods1)map.get(id)).getBalance()){ System.out.println("Insufficient inventory, issue failed! "); }else{ int c = ((Goods1) map.get(id)).getBalance()-count; ((Goods1) map.get(id)).setBalance(c); break; } }else{ //no matching id System.out.println("Sorry, this item does not exist! "); break; } } } public static void main(String[] args) { // TODO Auto-generated method stub TestGoods1 t = new TestGoods1(); t.get(); //t.add(); // t.show(); // t.inStore(); t.show(); t.outStore(); t.show(); Thank you for reading!
