Java - Strings and String Handling

Which statement best describes when to use StringBuilder instead of String in Java?

AUse <code>StringBuilder</code> when you need to change text many times efficiently.

BUse <code>StringBuilder</code> for fixed text that never changes.

CUse <code>String</code> when you want faster text modifications.

DUse <code>String</code> to save memory when changing text repeatedly.

Step-by-Step Solution

Solution:

Step 1: Understand the nature of String and StringBuilder
String objects are immutable, meaning they cannot be changed once created. Changing text creates new objects, which is slow and uses more memory.
Step 2: Identify when StringBuilder is better
StringBuilder allows changing text without creating new objects, making it efficient for many modifications.
Final Answer:
Use StringBuilder when you need to change text many times efficiently. -> Option A
Quick Check:
Many changes = StringBuilder [OK]

Quick Trick: Use StringBuilder for many text changes, String for fixed text [OK]
