来嘛，你要的１００分的帖子．．．．．来嘛，我是真诚的，请教你
第一题
1.建一个学校类， 包括成员变量 录取分数线（scoreline），并对其进行设置和获取的方法。
2.建一个学生类，包括考生姓名(name)，考号(id) 综合成绩(intgretResult) 体育成绩(sport)
并分别对 综合成绩，体育成绩进行设置和获取的方法。
3.建一个录取类，它判断学生是否 符合录取条件：综合成绩> 录取分数线，或者 综合成绩> 300并且体育成绩> 96，以上2种条件为被录取。否则不录取。
4.用main（）方法建立若干个对象，对符合录取条件的学生输出“录取”；
第二题
(1)设计一个表示二维平面空间上点的类point,包含有表示坐标位置的protected类型的成员变量X和Y，并写出设置和获取X，Y的Public的方法。
（2）设计一个表示二维平面上圆的类Circle 它继承自类point。还包含有表示圆半径protected类型的成员变量Radius，并写出设置和获取Radius的值的Public方法，计算圆面积的Public方法。
（3）设计一个表示圆柱体的Cylinder的类。它继承类Circle ，还有表示圆柱体高的protected类型的成员变量height，并写出设置和获取Radius的值的Public的方法。计算圆柱体体积的方法
（4）建若干个Cylinder对象，输出： 轴心坐标 ，半径，高以及体积的值。
要求：１．子类的构造方法调用父类的构造方法，对父类中的成员变量初始化。
２．写的类包含无参数和 有参数的构造方法。构造方法用与成员变量的初始化
希望大家帮助哈，我一般都是在线等待的．．．．
