VB.Net program to create an object of class inside another class

Write a VB.Net program to create an object of class inside another class

Here, we are going to create a Marks class and then create the Marks class object into a Student class.

Program :

Below is the source code for creating a class object within another class. The program given is compiled and successfully executed.

'VB.Net program to create an object of class inside another class.

Class Marks
    Private marks As Integer
    Sub SetMarks(ByVal m As Integer)
        marks = m
    End Sub
    Sub PrintMarks()
        Console.WriteLine(vbTab & "marks    : " & marks)
    End Sub
End Class
Class Student
    Private roll_no As Integer
    Private name As String
    Private fees As Integer
    Private address As String
    Public mark As New Marks
    Sub ReadInfo()
        Console.Write("Enter roll number: ")
        roll_no = Integer.Parse(Console.ReadLine())
        Console.Write("Enter student name: ")
        name = Console.ReadLine()
        Console.Write("Enter student fees: ")
        fees = Integer.Parse(Console.ReadLine())
        Console.Write("Enter student address: ")
        address = Console.ReadLine()
        Console.Write("Enter student marks: ")
    End Sub
    Sub PrintInfo()
        Console.WriteLine("Student Information")
        Console.WriteLine(vbTab & "Roll Number: " & roll_no)
        Console.WriteLine(vbTab & "Roll Name  : " & name)
        Console.WriteLine(vbTab & "Fees       : " & fees)
        Console.WriteLine(vbTab & "address    : " & address)
    End Sub
End Class
Module Module1
    Sub Main()
        Dim S As New Student
    End Sub
End Module
Enter roll number: 10
Enter student name: Shweta pal
Enter student fees: 15000
Enter student address: Noida
Enter student marks: 350
Student Information
Roll Number: 10
Roll Name : shweta pal
Fees : 15000
address : Noida
marks : 350

We created a Module1 module in the program above that includes the Main() function. Here, inside the Student Class, we created a Marks class and then created the Marks class object. The Student Class also includes 4 roll-no data members, name, fees, address. We built two ReadInfo() and PrintInfo() methods in the student class ().

To read the student information from the user, the ReadInfo() method is used. The PrintInfo() method is used on the console screen to print student details.

The Marks class includes two SetMarks() and PrintMarks() methods to set and print the values for marks.

The Main() method is the entry point for the program, where we created the User class object then called ReadInfo() and PrintInfo() using the student information object to read and print.
