Question

--------------Answer question below:--------------

In Java:

Given a Student class, create a class with following characteristics:

The class name should be ClassRoom.
Private variable students array to maintain the list of Student objects.
Function addStudent with input parameter name (string) and rollNo(int) adds a new student in “students” list.
Method getAllStudents should return all the students in ClassRoom.

Input
Jack

Jones

Marry

where,

First & Second line represent a student’s name and roll number. And so on.

Output

1 - Jack

2 - Jones

3 - Marry

Assume that,

Maximum “students” count can be 10.
