Description

设计一个教师类Teacher,要求：
属性有编号（int no）、姓名（String name）、年龄（int age）、所属学院（String seminary），为这些属性设置相应的get和set方法。
为Teacher类重写equals方法，要求：当两个教师对象的no相同时返回true。
重写Teacher类的toString方法，通过该方法可以返回“no: **, name:**, age: **, seminary: **”形式的字符串。

Input

两个教师对象的编号，姓名，年龄，学院

Output

教师的信息
两个教师是否相等

Sample Input

1 Linda 38 SoftwareEngineering
2 Mindy 27 ComputerScience

Sample Output

no: 1, name:Linda, age: 38, seminary: SoftwareEngineering
no: 2, name:Mindy, age: 27, seminary: ComputerScience
false
