Implementing a Stack Using an Array in Java
To implement a stack using an array in Java, you can follow these steps:
- Create a class named StackArray with the necessary methods for stack operations like push, pop, peek, isEmpty, and isFull.
- Declare an array to store the stack elements and initialize the top pointer to -1.
- Implement the push() method to add elements to the stack by incrementing the top pointer and inserting the element at that index.
- Implement the pop() method to remove elements from the stack by decrementing the top pointer and returning the element at that index.
- Implement the peek() method to view the top element of the stack without removing it.
- Implement the isEmpty() method to check if the stack is empty by examining the top pointer.
- 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.
