编写程序模拟两个村庄共用同一口井水，编写一个Village类，该类有一个静态的int型成员变量waterAmount，

用于模拟井水的水量。在主类的main()方法中创建两个村庄，一个村庄改变了waterAmount的值，另一个村庄查看waterAmount的值。

public class Main {
			public static void main(String[] args) {
				Village v1 = new Village();
				Village v2 = new Village();
				v1.drinkWater(180);//一个改变
				System.out.println("查看水量："+v2.seeWater());//一个看
				v2.drinkWater(260);//一个改变
				System.out.println("查看水量："+v1.seeWater());//一个看
				
			}
}
class  Village  {
		static int waterAmount =600 ;
		public  void drinkWater (double drink) {
			if(waterAmount >=  drink )
			waterAmount -= drink ;
		}
		public  double seeWater() {
			return waterAmount ;
		}
}
