Java Program to Evaluate Postfix Expression Using Stack

Introduction Postfix notation, also known as Reverse Polish Notation (RPN), is a mathematical notation in which operators follow their operands. In this notation, there are no parentheses required to denote the precedence of operators, and the evaluation of the expression is straightforward when using a stack. This guide will walk you through writing a Java …

Java Program to Implement a Queue Using Linked List

Introduction A queue is a linear data structure that follows the First In, First Out (FIFO) principle, where elements are added (enqueued) to the rear of the queue and removed (dequeued) from the front. Unlike an array-based implementation, a linked list-based queue dynamically adjusts its size as elements are added or removed. This guide will …

Java Program to Implement a Queue Using Array

Introduction A queue is a linear data structure that follows the First In, First Out (FIFO) principle, where elements are added (enqueued) to the rear and removed (dequeued) from the front. This guide will walk you through writing a Java program that implements a queue using an array. The queue operations include enqueue, dequeue, peek, …

Java Program to Implement a Stack Using Linked List

Introduction A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. Unlike arrays, which have a fixed size, a linked list-based stack dynamically grows and shrinks as elements are added or removed. This guide will walk you through writing a Java program that implements a stack using a singly …

Java Program to Check if a Linked List is a Palindrome

Introduction A palindrome is a sequence of elements that reads the same forwards and backwards. Checking if a linked list is a palindrome involves determining if the elements in the list are symmetrical around its center. This guide will walk you through writing a Java program that checks if a singly linked list is a …

Java Program to Insert a Node at the Beginning of a Linked List

Introduction Inserting a node at the beginning of a linked list involves adding a new node before the current head node, then updating the head to point to the new node. This operation is commonly used when you need to prepend data to the list. This guide will walk you through writing a Java program …

Java Program to Delete a Node from a Linked List

Introduction Deleting a node from a linked list is a fundamental operation that involves removing a specific node and adjusting the pointers of the surrounding nodes to maintain the list’s structure. This guide will walk you through writing a Java program that deletes a node from a singly linked list. Problem Statement Create a Java …
