（4）编写程序模拟两个村庄公用同一口水井。编写Village类模拟村庄，该类中有一个静态变量描述水井中的水量，一个静态方法查看水井中的水量。在主类中创建两个村庄，一个村庄喝了井中的水，另一个村庄查看水量少了。

好的，以下是你要求的代码：

class Village {
    static int waterInWell = 1000;

    static void checkWaterInWell() {
        System.out.println("Water in the well: " + waterInWell + "L");
    }

    void drinkWater(int amount) {
        waterInWell -= amount;
        System.out.println("Drank " + amount + "L of water from the well.");
    }
}

public class Main {
    public static void main(String[] args) {
        Village village1 = new Village();
        Village village2 = new Village();

        village1.drinkWater(500);
        Village.checkWaterInWell();

        village2.drinkWater(300);
        Village.checkWaterInWell();
    }
}

运行以上代码，输出结果如下：

Drank 500L of water from the well.
Water in the well: 500L
Drank 300L of water from the well.
Water in the well: 200L

希望对你有所帮助！
