Are you still using String for frequent modifications? 🤔 It’s time to switch to StringBuilder for better performance and efficiency! In this video, we deep dive into:

🔹 charAt(index) – Retrieve a specific character from the StringBuilder, just like an array index. Perfect for checking or processing individual characters!

🔹 setCharAt(index, char) – Need to modify a character at a specific position? This method allows you to replace a character efficiently without creating a new object.

🔹 length() – Quickly determine the number of characters stored in your StringBuilder. Unlike Strings, it dynamically adjusts as you modify content!

🔹 insert(index, value) – Want to add new characters or strings at a specific position? This method lets you insert text anywhere within the existing content.

🔹 append(value) – The most used method! Effortlessly add text, numbers, or other data types at the end of your StringBuilder, making concatenation ultra-fast compared to regular Strings.

🔥 Bonus: Ever wondered why StringBuilder is faster than String? I explain the storage algorithm differences between String vs. StringBuilder, helping you understand why StringBuilder is the preferred choice for dynamic string modifications!
