Implementing a Queue Using Stacks in Java

Understanding how different data structures interact is a cornerstone of robust software engineering and a frequent topic in technical interviews. This text-based course guides you through the logic and implementation of constructing a fully functional Queue using only two Stacks in Java. You will transition from basic theory to writing optimized, clean code that handles real-world data flow. What you'll learn: Understand the core differences between First-In-First-Out (FIFO) and Last-In-First-Out (LIFO) structures; Implement efficient enqueue and dequeue operations using Java's built-in Stack class; Analyze the time and space complexity of your implementation using Big O notation; Write clean, modern Java code with proper type safety and generics; Handle edge cases such as empty states and potential underflow errors. You will start with foundational definitions of stacks and queues, explore the step-by-step algorithms for element transfer, and finally write and analyze the complete Java implementation. This course is designed for beginner Java programmers and computer science students looking to strengthen their data structure fundamentals; no prior experience with custom structure implementation is required.
