[原创]JAVA解决喝汽水问题

问题：一瓶汽水单价2.5元，四个瓶盖或者两个瓶子可以换取一瓶汽水。给定金额得出一共能喝几瓶汽水？

实现：

#cat drink.java

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class drink {

    public static void main(String[] args){

        System.out.println("汽水单价为2.5元,四个瓶盖或者两个空瓶可以换取一瓶汽水。请输入您购买的金额: ");

        InputStreamReader isr = new InputStreamReader(System.in);

  		BufferedReader br = new BufferedReader(isr);

        double money = 0.0;

        try {

            money = Double.valueOf(br.readLine()).doubleValue();

        } catch (IOException e) {

            e.printStackTrace();

        }

        System.out.println("您购买汽水的金额是: " + money);

        double n = money / 2.5;

        int num = (int)n;

        int gaizi = num;

        int kongping = num;

        while (gaizi >= 4 || kongping >= 2) {

    		int i = (gaizi / 4) + (kongping / 2);

    		num = num + i;

    		gaizi = gaizi % 4 + i;

    		kongping = kongping % 2 + i;

        }

        System.out.println("您一共可以喝到的汽水数量是: " + num + ",剩余盖子数: " + gaizi

            + ",剩余空瓶数: " + kongping);

    }

}

效果图略。
