Java实现商品的查找、添加、出库、入库操作完整案例
本文实例讲述了Java实现商品的查找、添加、出库、入库操作。分享给大家供大家参考，具体如下：
packagecom.jredu.oopch08;
publicclassGoods1{
privateintid;
privateStringname;
privatedoubleprice;
privateStringuom;
privateintbalance;
publicGoods1(intid,Stringname,doubleprice,Stringuom,intbalance){
super();
this.id=id;
this.name=name;
this.price=price;
this.uom=uom;
this.balance=balance;
}
publicintgetId(){
returnid;
}
publicvoidsetId(intid){
this.id=id;
}
publicStringgetName(){
returnname;
}
publicvoidsetName(Stringname){
this.name=name;
}
publicdoublegetPrice(){
returnprice;
}
publicvoidsetPrice(doubleprice){
this.price=price;
}
publicStringgetUom(){
returnuom;
}
publicvoidsetUom(Stringuom){
this.uom=uom;
}
publicintgetBalance(){
returnbalance;
}
publicvoidsetBalance(intbalance){
this.balance=balance;
}
}
packagecom.jredu.oopch08;
importjava.util.HashMap;
importjava.util.Iterator;
importjava.util.Map;
importjava.util.Scanner;
importjava.util.Set;

map.put(goods3.getId(),goods3);
map.put(goods4.getId(),goods4);

}
publicstaticbooleancheck(intid){

}

Goods1goods6=newGoods1(id,name,price,uom,balance);
map.put(goods6.getId(),goods6);
System.out.println("新增成功！");
}
}
publicstaticvoidshow(){//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();

while(iter.hasNext()){

System.out.print(entry.getKey()+"\t");
System.out.println(entry.getValue().getName()+"\t\t"+entry.getValue().getPrice()+"\t"

}
}

for(inti=0;i((Goods1)map.get(id)).getBalance()){
System.out.println("库存不足，出库失败！");
}else{
intc=((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;
}
}
}
publicstaticvoidmain(String[]args){
