Java语言怎么实现水池应用题，水池的水管可以灌水也可以放水，灌水的时间是放水的2倍水池一直有水，水池灌水和放水的组合有几种，怎么用程序去实现判断的呢？如果不知道水池容量怎么用程序实现

Answer 1

如图

代码如下

import java.util.ArrayList;
import java.util.List;

public class PoolApplication {
    static class WaterLevel {
        private int capacity; // 水池容量
        private int currentLevel; // 当前水位

        public WaterLevel(int capacity) {
            this.capacity = capacity;
            this.currentLevel = 0;
        }

        public boolean isOverflow() {
            return currentLevel > capacity;
        }

        public void fillPool() {
            currentLevel = capacity;
        }

        public void drainPool() {
            currentLevel = 0;
        }

        public void fillAndDrainPoolCombination() {
            List<String> combinations = new ArrayList<>();

            for (int fillTime = 1; fillTime <= capacity * 2; fillTime++) {
                for (int drainTime = 1; drainTime <= fillTime / 2; drainTime++) {
                    if (fillTime - drainTime <= capacity) {
                        combinations.add("灌入水量：" + fillTime + "，放出水量：" + drainTime);
                    }
                }
            }

            System.out.println("共有" + combinations.size() + "种灌水和放水组合：");
            for (String combination : combinations) {
                System.out.println(combination);
            }
        }
    }

    public static void main(String[] args) {
        int poolCapacity = 10; // 水池容量

        WaterLevel pool = new WaterLevel(poolCapacity);

        pool.fillAndDrainPoolCombination();
    }
}
