A stack is a simple data structure for storing data. In stack, the order in which the data arrives is important. A pile of books is a good example of stack. A stack is an ordered list in which insertion and deletion are done at one end, where end is called top. The last element inserted is the first one to be deleted. Hence, it is called Last in First Out (LIFO) or First in Last Out (FILO) list

In this post, we'll see the other way of implementing Stack is by Linked List. This is continuation of the previous post about Array implementation of Stack.

In this implementation, push operation is implemented by inserting element at the beginning of the list. Pop operation is implemented by deleting the node from the beginning.

Even you can throw exception instead of printing message in case of pop operation when stack is empty.

**Generic Implementation of Stack as Linked List****ListNode****Generic Stack****Demo**Performance and Limitations

**Performance**: Let n be the number of elements in the stack.- Space Complexity for n push operations : O(n)
- Time Complexity of push : O(1)
- Time Complexity of pop : O(1)
- Time Complexity of isEmpty : O(1)
- Time Complexity of isStackFull : O(1)
- Time Complexity of deleteStack : O(1)

**Limitations**: The size of the stack must be defined in prior and cannot be changed.Download code : ListNode LinkedStack LinkedStackDemo GenericListNode GenericLinkedStack GenericStackDemo

good explanation...But i am not able to copy the code in your post. I think you have used the image for the program. Could you please post the code instead of image..
