HOW TO USE STACK IN VB.NET

Stack is one of another easy to use VB.NET Collections . Stack follows the push-pop operations, that is we can Push Items into Stack and Pop it later also it follows the Last In First Out (LIFO) system. That is we can push the items into a stack and get it in reverse order. Stack returns the last item first.

Commonly used methods :

Push : Add (Push) an item in the stack datastructure

Syntax : Stack.Push(Object)

Object : The item to be inserted.

Pop : Pop return the item last Item to insert in stack

Syntax : Stack.Pop()

Return : The last object in the Stack

Contains : Check the object contains in the stack

Syntax : Stack.Contains(Object)

Object : The specified Object to be seach

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, 
 ByVal e As System.EventArgs) Handles Button1.Click
        Dim stackTable As New Stack
        stackTable.Push("Sun")
        stackTable.Push("Mon")
        stackTable.Push("Tue")
        stackTable.Push("Wed")
        stackTable.Push("Thu")
        stackTable.Push("Fri")
        stackTable.Push("Sat")
        If stackTable.Contains("Wed") Then
            MsgBox(stackTable.Pop())
        Else
            MsgBox("not exist")
        End If
    End Sub
End Class

When you execute this program add seven items in the stack . Then its checks the item "Wed" exist in the Stack. If the item exist in the Stack , it Pop the last item from Stack , else it shows the msg "Not Exist"
