淮海工学院java实验二

淮海工学院计算机工程学院实验报告书课程名：《面向对象程序设计A》题目：实验二Java面向对象编程初步(2)______ 班级：____软嵌151学号：2015123352姓名：韩吉_一.实验目的(1)通过实验，进一步掌握类的定义，尤其是类中方法（包含构造方法）的定义。

掌握对象的创建方法及对象成员变量和方法的调用；(2)通过编写图形界面的程序，完成对象的创建和调用;(3)能够通过类图来描述程序中类的结构。

二. 实验内容及要求(1)定义教师类Teacher，包含属性工号，姓名，性别，所在部门，职称，职位，专业，学历；定义若干个构造方法，完成对象的各种初始化需要；定义若干个分别能够获取和修改成员变量的方法，如获取工号/修改工号;获取学历/修改学历等；定义toString()方法，能够输出教师的所有相关信息。

(40分)(2)编写字符界面的程序，能够创建若干个教师对象，并输出教师的相关信息；(20分)(3)要求在报告中能够画出类图来描述类的结构(15分)(4)编写图形界面的程序，能够创建若干个教师对象，并输出教师的相关信息。

(25分)可以参照实验指导书中第二个实验的最后一个程序示例。
