Write a generic program to implement student information system. User could be shown following menu. Press 5 to quit 1 - To add a new student 2 - Find a student by student Id 3 - Delete a student by student Id 4 - List all students On selecting 1, user should be asked for all the attribute values of the student On selecting 2, user should be asked for the student Id. Search should be performed accordingly. On selecting 3, user should be asked for the student Id. Delete should be performed accordingly. On selecting 4, user should be shown all the students with the details. Use the startup code to do the following 1. Convert the classes and methods to generic where it is necessary [04 Marks] 2. Wirte the code for the class MyArrayImpl [14 Marks) 3. Write the code for the class SIS [10 Marks) 4. Write the code for Student class [02 Marks] 5. Write the code for SISTest class [08 Marks] 6.
