在作业1的Employee和EmployeeDemo两个类基础上修改
1,重写Employee类的toString方法,返回Employee类的相关信息的字符串形式
重写Employee类的equals方法,如果两个Employee实例的名字和所属部门相同,返回true;
并在EmployeeDemo类里面验证上述两个方法
2,定义Clerk、Salesman、Engineer三个类,分别继承自Employee
为Salesman增加一个年销售额属性
为Engineer增加一个年消化人月数属性
3,将下面的描述反映到程序里
普通员工年终奖金分配方案为月薪×2
Salesman:销售额×2%+月薪×1.8
Engineer:年消化人月数×300+月薪×2.5
Clerk:月薪×2.5-1 of the Employee in the operation and EmployeeDemo two classes based on the modification 1, rewrite the Employee class toString method to return to Employee class-related information to rewrite the string form of Employee class equals method, if the two examples of Employee s name and their the same sector, return true and EmployeeDemo the above-mentioned two types of authentication methods inside 2, the definition of Clerk, Salesman, Engineer of three categories, respectively, inherited from the Employee as a Salesman for an additional annual sales for an additional attribute for the Engineer who was the number

简介
JavaEE在开发的时候,如果是系统内部常量,一般提倡用枚举常量类,写在单独的类中,但是经常要修改的变量,比如数据源配置,如果存在数据库中,有种浪费。但是存在TXT中扩展性不好,就笔者观察,一般的程序员都喜欢把经常修改的常量存在xml文件或者properties文件。
存在xml文件最大的好处是扩展性很好,一般用sax或者dom这两个方向的框架,比如DOM4J,JDOM等。Sun推出的JAXM(Java API for XML Messaging)也是用的DOM4J。由于SAX的处理方式类似流媒体,是逐行的,不需要全部加载。而DOM是全部加载在内存,生成树。因而SAX的读取比DOM性能好,但是修改的话DOM略胜一筹。properties文件的扩展性不如xml,但是有很多xml没法实现的优势,比如加密之类的~

笔者根据自己开发中感受,写了一个工具包,用来体现读取xml或者properties的流程,大家在使用的时候记得修改文件路径。一共包含五个文件.本demo主要是用来模拟读取数据库的账户和密码的,读者可以在此基础上扩展。-Brief introduction
JavaEE development at the time, if the system constants are generally used to promote constant enumeration type, write in a separate category, but often want to modify the variables, such as the data source configuration, if the database exist, in one waste. But the existence of bad TXT extension on my observation, the programmers in general are often modified to enjoy the constant existence xml documents or document properties.
Xml files exist to expand the biggest benef
