AIM:
To write a java program to get the details of students and staff using inheritance and method overriding.
PROCEDURE:
1)Start the program.
2)Define the class personal and declare the necessary variables.
3)Define function, getdata() to get the details.
4)Define function, display() to print the details.
5)Declare the class marks and staff and get the details of marks, staff.
6)Overload the methods getdata() and display().
7)Declare the main class.
8)To enter the choice in main class using switch condition.
9)To get the input and display the details.
10)Save and execute the program.
11)Exit the program.
