Mastering Queues in Java Mastering Queues in Java: A Step-by-Step Implementation (Array Based) In this tutorial, we’ll implement an Array-Based Queue in Java. The code includes detailed comments to explain what each part does. Queue Class // Queue class manages all operations using an array public class Queue { private int[] queueArray; // Array to hold queue elements private int front; // Index of the front element private int rear; // Index of the rear element private int capacity; // Maximum size of the queue private int currentSize; // Current number of elements // Constructor initializes the queue with given capacity public Queue(int capacity) { this.capacity = capacity; this.queueArray = new int[capacity]; this.front = 0; this.rear = -1; this.currentSize = 0; } // Check if the queue is empty public boolean isEmpty() { return this.curren...

Mastering Stacks in Java Mastering Stacks in Java: A Step-by-Step Implementation (Array Based) In this tutorial, we’ll implement an Array-Based Stack in Java. The code includes detailed comments to explain what each part does. Stack Class // Stack class manages all operations using an array public class Stack { private int[] stackArray; // Array to hold stack elements private int top; // Index of the top element private int capacity; // Maximum size of the stack // Constructor initializes the stack with given capacity public Stack(int capacity) { this.capacity = capacity; this.stackArray = new int[capacity]; this.top = -1; // Indicates empty stack } // Check if the stack is empty public boolean isEmpty() { return this.top == -1; } // Check if the stack is full public boolean isFull() { return this.top == this.capacity - 1; } // Push an element onto...
