创建Game类,运行代码如下:
1 package org.hanqi.pn0120; 2 3 public class Game { 4 5 private String name; 6 private String category; 7 private int totalcost = 10000; 8 9 public String getName() { 10 return name; 11 } 12 public void setName(String name) { 13 this.name = name; 14 } 15 public String getCategory() { 16 return category; 17 } 18 public void setCategory(String category) { 19 this.category = category; 20 } 21 public int getTotalcost() { 22 return totalcost; 23 } 24 public void setTotalcost(int totalcost) { 25 this.totalcost = totalcost; 26 } 27 28 public Game(String name, String category) { 29 super(); 30 this.name = name; 31 this.category = category; 32 } 33 34 public void cost1(int cost) 35 { 36 if(cost <= 0) 37 { 38 System.out.println("做游戏的钱呢?!"); 39 } 40 else if(cost>this.totalcost) 41 { 42 int excess=cost-this.totalcost; 43 System.out.println("超出预算了,超了"+excess+"金额的预算"); 44 } 45 else 46 { 47 this.totalcost=cost; 48 System.out.println("这次预算是"+this.totalcost); 49 } 50 } 51 52 private int sales; 53 public int getSales() 54 { 55 return this.sales; 56 } 57 public void money(int number,int price) 58 { 59 if(number<=0) 60 { 61 System.out.println("一份都没卖出去,赔钱了,公司要倒闭"); 62 } 63 else if(price<=0) 64 { 65 System.out.println("为什么定价是0?"); 66 } 67 else if(price>50) 68 { 69 System.out.println("定价太高了"); 70 } 71 else 72 { 73 this.sales=number*price; 74 System.out.println("销售额是"+sales); 75 76 if(this.sales<this.totalcost) 77 { 78 int debt = this.totalcost-this.sales; 79 System.out.println("入不敷出,公司倒闭,欠了 "+debt+" 金额的债务"); 80 } 81 else 82 { 83 int profit = this.sales-this.totalcost; 84 System.out.println("挣钱了,利润是"+profit); 85 } 86 } 87 } 88 89 public static void main(String[]args) 90 { 91 Game myGame = new Game("你与我的星空","Galgame"); 92 System.out.println("游戏名称是:"+myGame.getName()); 93 System.out.println("游戏类型为:"+myGame.getCategory()); 94 myGame.cost1(-10000); 95 myGame.cost1(20000); 96 myGame.cost1(2000); 97 myGame.money(0, 25); 98 myGame.money(14, 0); 99 myGame.money(200, 88); 100 myGame.money(200, 25); 101 } 102 }
则运行代码为:
