Question

Accepted Answer

String is immutable, while StringBuilder is mutable. StringBuilder is faster and more memory efficient for string manipulation.

String is immutable, meaning once created, it cannot be changed. StringBuilder is mutable, allowing for efficient string manipulation.
StringBuilder is faster than String for concatenating multiple strings, as it does not create a new string object each time.
String uses more memory as it creates a new object every time it is modified, while StringBuilder modifies the existing object.
Use String for simple string operations where immutability is not an issue. Use StringBuilder for complex string manipulations to improve performance and memory usage.
String Interpolation can be efficiently done using StringBuilder for dynamic string construction.
String Manipulation like concatenation, insertion, deletion, etc. is better performed using StringBuilder for improved efficiency.
