Java Strings Explained: String vs StringBuilder vs StringBuffer 🔥 | Fast, Safe & Immutable!

Confused between String, StringBuilder, and StringBuffer in Java? 🤔

Here’s a quick and fun visual guide to remember:

String → Immutable 🪨 (Once written, can’t be changed!)

StringBuilder → Fast, single-threaded 📓 (Easy to edit, but only one user at a time)

StringBuffer → Thread-safe, multi-threaded 📝 (Multiple users can edit safely, but slightly slower)

💡 Tip: Memorize this one line – 'String = immutable, StringBuilder = fast single-threaded, StringBuffer = safe multi-threaded.'
