Applications of Stack

Stack Data Structure in Java

The Stack can be visualized as the collection of elements arranged one on top of the other. It can typically support the two primary operations are pushing(adding) the elements onto the stack and popping(removing) elements from the stack....

Implementation of Stack:

Stack can be implemented using the various underlying the data structures such as the arrays or linked lists....

Operations in Stack

There are only few counted operations can be performed in Stack Data Structure in Java as mentioned below:...

Algorithm for the Operations

Operation Algorithm Complexity 1. Push Operation Check if stack is full using isFull() method.If stack is full then print an error message(“Stack Overflow”) and return.Increment the ‘top’ to move to next empty position in the stack.Insert the new element value into stackArray.Print the message indicating the element has been pushed onto the stack.Time Complexity: O(1)Space Complexity: O(1) 2. Pop Operation Check whether if the stack is empty using isEmpty() method.If stack is empty, print the error message (“Stack underflow”) and return -1.Retrieve the top element from the stackArray.Decremen the top to remove the top element from stack.Return the popped element in stack.Time Complexity: O(1)Space Complexity: O(1) 3. Peek Operation Check If stack is empty using isEmpty() method.If stack is empty,print the error message(“Stack is empty”) and return -1.Return the top element from stackArray without removing it.Time Complexity: O(1)Space Complexity: O(1) 4. IsEmpty Operation It returns true if stack is empty that indicates top variable is -1 that means no elements in stack, otherwise false.Time Complexity: O(1)Space Complexity: O(1) 5. isFull Operation It can returns true if stack is full i..e if top variable has reached the maximum capacity of stack(maxSize-1). Other =wise it returns false.Time Complexity: O(1)Space Complexity: O(1)...

Step by Step Implementation of Stack Data Structure

Define the class for the StackWe can declare the necessary instance variables such as the size of stack, an array can store the elements and the variable to track the top of element of the stack.Implement the constructor to initialize the stack with the given size.Implement the methods to perform the stack operations such as push, pop, peek, isEmpty and isFull.Write the algorithms for the each operation and taking care to handle the edge cases such as overflow or underflow.Print the results of the operation based on the requirements of the stack....
