对象

package com.fqs.goods;

public class Goods {
    private int id;
    private String name;
    private double price;
    private int  geShu;

    public Goods() {
    }

    public Goods(int id, String name, double price, int geShu) {
        this.id = id;
        this.name = name;
        this.price = price;
        this.geShu = geShu;
    }

    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 int getGeShu() {
        return geShu;
    }

    public void setGeShu(int geShu) {
        this.geShu = geShu;
    }

}

调用方法

package com.fqs.goods;

import sun.font.FontRunIterator;

public class GoodsTest {
    public static void main(String[] args) {
        Goods g1=new Goods(1,"apple",5.0,8);
        Goods g2=new Goods(2,"orage",9.0,3);
        Goods g3=new Goods(3,"rice",0.5,3);
        //存放3个商品信息的数组 类型是Goods
       Goods []arr=new Goods[3];
        arr[0]=g1;
        arr[1]=g2;
        arr[2]=g3;

        //遍历数组
        for (int i = 0; i < 3; i++) {
            System.out.println(arr[i].getId()+" "+arr[i].getName()+" "+arr[i].getPrice()+" "+arr[i].getGeShu());

        }

    }
