Implementing a Stack Using an Array in Java

Implementing a Stack Using an Array in Java

To implement a stack using an array in Java, you can follow these steps:

  1. Create a class named StackArray with the necessary methods for stack operations like push, pop, peek, isEmpty, and isFull.
  2. Declare an array to store the stack elements and initialize the top pointer to -1.
  3. Implement the push() method to add elements to the stack by incrementing the top pointer and inserting the element at that index.
  4. Implement the pop() method to remove elements from the stack by decrementing the top pointer and returning the element at that index.
  5. Implement the peek() method to view the top element of the stack without removing it.
  6. Implement the isEmpty() method to check if the stack is empty by examining the top pointer.
  7. Implement the isFull() method to check if the stack is full by comparing the top pointer with the array length.

By following these steps, you can easily implement a stack using an array in Java.
