public class Weapon

有两个地方错了
一、Tank的构造函数中，应该先调用父类的构造函数。具体做法如下
public Tank(double Weight, double Hit, double Price, double DenyHit, double oil, double drive, int healthy):base(Weight ,Hit,Price ,DenyHit ) {
this.oil = oil;
this.drive = drive;
this.healthy = healthy;
}
就是用base()来调用父类构造函数
二、在Main()函数中，新建Tank类对象时，应该注意到Tank类的构造函数有7个参数，而不是5个，所有改成
Tank t = new Tank(2000, 800, 500000, 600, 100, 10, 10);
就可以了！！
我已经给你改好了，当初始化子类的时候会系统会调用默认的父类构造函数，所以要我们手动来调用父类构造函数
