案例
一、这里主要承接案例一的实例,主要运用点是用“\t”代替自行敲出的空格间隔,和运用变量来自动的解除金额结果下面我来贴出代码
第一种:
1.引用“\t”代码:
1 public class SuperMarket { 2 public static void main(String[] args) { 3 System.out.println("\t\t人人乐白金假日购物广场(RenRenLe)\t\t"); 4 System.out.println("店\t号:S131\t\t机号:P026\t\t流水号:244"); 5 System.out.println("收银员:0312\t\t\t\t\t日期:2014.12.14"); 6 System.out.println("============================================="); 7 System.out.println("\t商品名\t\t数量\t\t单价\t\t金额"); 8 System.out.println("1\t小肥羊火锅汤料(清汤)110g"); 9 System.out.println("6935953399984\t\t1\t\t15.80\t\t15.80"); 10 System.out.println("\t\t\t特价商品"); 11 System.out.println("2\t海底捞清汤火锅汤料110g"); 12 System.out.println("6942032700753\t\t1\t\t17.90\t\t17.90"); 13 System.out.println("3\t青岛啤酒瓶装600ml"); 14 System.out.println("6923740100059\t\t1\t\t4.50\t\t4.50"); 15 System.out.println("4\t青岛啤酒瓶装600ml"); 16 System.out.println("6923740100059\t\t1\t\t4.50\t\t4.50"); 17 System.out.println("5\t青岛啤酒瓶装600ml"); 18 System.out.println("6923740100059\t\t1\t\t4.50\t\t4.50"); 19 System.out.println("合计:\t\t\t\t\t\t\t\t\t47.20"); 20 } 21 }
2.运行结果:
第二种
1.运用变量:
1 public class SuperMarketRenRenle { 2 public static void main(String[] args) { 3 System.out.println("\t\t人人乐白金假日购物广场(RenRenLe)\t\t"); 4 System.out.println("店\t号:S131\t\t机号:P026\t\t流水号:244"); 5 System.out.println("收银员:0312\t\t\t\t\t日期:2014.12.14"); 6 System.out.println("============================================="); 7 System.out.println("\t商品名\t\t数量\t\t单价\t\t金额"); 8 System.out.println("1\t小肥羊火锅汤料(清汤)110g"); 9 int n = 1; //代表的是整数
10 float f1 = 15.80f; //代表的是小数
11 float f2 = 17.90f; //代表的是小数
12 float f3 = 4.50f; //代表的是小数
13 System.out.println("6935953399984\t\t"+n+"\t\t"+f1+"\t\t"+(n*f1)+""); 14 System.out.println("\t\t\t特价商品"); 15 System.out.println("2\t海底捞清汤火锅汤料110g"); 16 System.out.println("6942032700753\t\t"+n+"\t\t"+f2+"\t\t"+(n*f2)+""); 17 System.out.println("3\t青岛啤酒瓶装600ml"); 18 System.out.println("6923740100059\t\t"+n+"\t\t"+f3+"\t\t\t"+(n*f3)+""); 19 System.out.println("4\t青岛啤酒瓶装600ml"); 20 System.out.println("6923740100059\t\t"+n+"\t\t"+f3+"\t\t\t"+(n*f3)+""); 21 System.out.println("5\t青岛啤酒瓶装600ml"); 22 System.out.println("6923740100059\t\t"+n+"\t\t"+f3+"\t\t\t"+(n*f3)+""); 23 float total = (n*f1)+(n*f2)+(n*f3)+(n*f3)+(n*f3); 24 System.out.println("\t合计:\t\t\t\t\t\t\t\t"+total+""); 25 } 26 }
2.运行结果:
