Test . inheritance

Q1. Test01.java 상속 관계로 구현하시오.

Student.java				- 필드 : String name, int age, String School
							- 메소드 : Constructor, output()
Worker.java					- 필드 : String name, int age, String job
							- 메소드 : Constructor, output()
→ 부모클래스는 알아서 만들어보자!(Human)

Q2. Test02.java 상속 관계로 구현하시오.
Notebook.java				- 필드 : String model, int price, int battery
							- 메소드 : Constructor, output()	
Tablet.java					- 필드 : String model, int price, int battery, String pen
							- 메소드 : Constructor, output()
→ 부모클래스는 알아서 만들어보자!(Computer)						

Q3. Test03.java 상속 관계로 구현하시오.
SalaryWorker.java			- 필드 : String name, String dept, int salary
							- 메소드 : Constructor, int pay(), output()	
SalesWorker.java			- 필드 : String name, String dept, int salary , double salesIncentive
							- 메소드 : Constructor, int pay(), output(), int salesPay()
PartTimeWorker.java			- 필드 : String name, String dept, int workTime, int payPerHour
							- 메소드 : Constructor, int pay(), output()
→ 부모클래스는 알아서 만들어보자!(Employee)
