1元钱买一瓶汽水，2个空瓶换一瓶汽水，3个瓶盖换一瓶汽水，问：3块钱能和多少瓶汽水？

代码实现：

public class DrinkWater {public static void main(String[] args) {Scanner scan = new Scanner(System.in);System.out.print("请输入金额：");int money = scan.nextInt(); //金额int bottle = money; //空瓶int cap = money; //瓶盖int sum = money; //可以喝的汽水的总瓶数System.out.println(money+"元直接买的瓶数："+sum);while(true){//换取的饮料瓶数int changeBottle = bottle/2;int changeCap = cap/3;int change = changeBottle + changeCap;//换取后剩下int balBottle = bottle%2;int balCap = cap%3;//当前已经喝的总瓶数sum = sum + change;//饮料喝完后的总的空瓶数喝瓶盖数bottle = balBottle + change;cap = balCap + change;if(bottle<2 && cap <3){break;}}System.out.println(money+"元可以喝到的总的瓶数："+sum);scan.close();}}
