输出效果

代码：

 1 package com.oracle.Shopping;
 2 //修饰符+class+类名
 3 public class Shopping {
 4     //修饰符 + 返回值 +主方法（）{}
 5     public static void main(String[] args) {
 6         //打印方法
 7         System.out.println("--------------------商城库存--------------------");
 8         //一维数组，静态初始化
 9         String[] list = {"品牌型号","尺寸","价格","库存"};//静态初始化
10         String[] brand = new String[]{"MacBookAir","ThinkpadT450","ASUS-FL5800"};
11         //String[] brand = {"MacBookAir","ThinkpadT450","ASUS-FL5800"};
12         //String[] brand = new String[3];//动态初始化，然后赋值
13         double[] size = new double[3];
14         size[0]=13.3;
15         size[1]=14.0;
16         size[2]=15.6;
17         double[] money = {6988.88,5999.99,4999.5};
18         int[] repertory={5,10,18};
19             System.out.print(list[0]+"\t"+"\t"+list[1]+"\t"+list[2]+"\t"+list[3]+"\t");
20         System.out.println();
21         //需要确保一维数组的下标一致（下标不一致暂时是重新打印的）
22         int sum = 0;//设置总库存数初始值为0
23         double amount = 0;//设置总金额初始值为0
24         //for遍历
25         for(int i=0;i<brand.length;++i){
26             //打印方法，\t表示Tab键
27             System.out.println(brand[i]+"\t"+size[i]+"\t"+money[i]+"\t"+repertory[i]+"\t");
28             //计算库存数
29             sum = sum+ repertory[i];
30             //计算总金额
31             amount =amount+ money[i]*repertory[i];        
32         }    
33         System.out.println("------------------------------------------------");
34         System.out.println("总库存数："+sum);
35         System.out.println("库存商品总金额："+amount);
36     }
