In this post, we will learn Contact Details of Hosteller Program in java Programming language.
Question:
SNMR College of Engineering and Technology wants to create an application to store their students details as well as the details of hostellers.
In case of any changes to be made to the attributes, admin can update the details like room number and phone number of the hosteler.
Develop a program to implement this scenario.
Create a public class Student with protected attributes :
int studentId
String name
int departmentId
String gender
String phone
Create a public class Hosteller with private attributes
String hostelName
int roomNumber
Make this class inherit the Student class, as it holds all the properties of Student.
Use appropriate public getters and setters for both the classes.
Write a class Main with the main function.
In Main class get the input of the hosteller using the method :
public static Hosteller getHostellerDetails().
Invoke this method from the main method and then modify the room number and phone number, if needed.
Sample Input 1:
Enter the Details:
Student Id
1
Student Name
John
Department Id
101
Gender
Male
Phone Number
9876543210
Hostel Name

Room Number
10
Modify Room Number(Y/N)
Y
New Room Number
11
Modify Phone Number(Y/N)
Y
New Phone Number
9876543121
Sample Output 1:
The Student Details
1 John 101 Male 9876543121 YMCA 11
Sample Input 2:

Modify Room Number(Y/N)
N
Modify Phone Number(Y/N)
N
Sample Output 2:
The Student Details:
2 John Paul 112 Male 9885526536 YMBA 5
