ArrayList of Points

Objetive

Create a structure named "Point3D" to represent a point in 3D space with coordinates X, Y, and Z.

Create a program that has a menu where the user can:

Add data for one point
Display all the entered points
Exit the program
The program should use ArrayLists instead of arrays.

Code

Imports System
Imports System.Collections
Namespace Point3D
    Class Program
        Structure Point3D
            Private x, y, z  As Double
        End Structure

        Private Shared Sub Main(ByVal args As String())
            Dim [exit] As Boolean = False
            Dim list As ArrayList = New ArrayList()
            Dim points As Point3D = New Point3D()
            Dim answer As String

            Do
                Console.WriteLine("1. Add data for one point")
                Console.WriteLine("2. Display all the entered points")
                Console.WriteLine("x. Display all the entered points")
                Console.WriteLine()
                Console.Write("Enter a option: ")
                answer = Console.ReadLine()

                If answer.ToLower() = "x" Then
                    [exit] = True
                ElseIf answer = "1" Then
                    Console.Write("Point x: ")
                    list.Add(Convert.ToInt32(Console.ReadLine()))
                    Console.Write("Point y: ")
                    list.Add(Convert.ToInt32(Console.ReadLine()))
                    Console.Write("Point z: ")
                    list.Add(Convert.ToInt32(Console.ReadLine()))
                End If
            Loop While Not [exit]
        End Sub
    End Class
End Namespace
