Java String Handling for Developer Interviews

String manipulation is one of the most frequently tested topics in technical interviews, yet many developers struggle with the underlying memory mechanics and performance implications. This course helps you build a rock-solid understanding of how Java handles text under the hood so you can solve coding challenges with optimal efficiency. You will transition from basic string operations to writing high-performance, memory-aware Java code. What you will learn: Understand the core differences between String, StringBuilder, and StringBuffer; Master the mechanics of the String Constant Pool and heap memory allocation; Practice solving common interview coding challenges involving anagrams, palindromes, and string parsing; Apply modern Java features like text blocks and pattern matching for cleaner code; Analyze the time and space complexity of different string manipulation algorithms. The course begins with foundational concepts, memory architecture, and basic operations before moving into advanced optimization techniques and actual interview scenarios. This course is designed for beginner to intermediate Java developers preparing for technical interviews, with no advanced prerequisites required.
