String and StringBuilder are both classes in Java that are used to manipulate sequences of characters. However, they have fundamental differences in terms of their immutability, performance, and use cases.

### Immutability:

1. String:
- Strings in Java are immutable, meaning their values cannot be changed after they are created.
- If you want to modify a String, such as concatenating two Strings together, a new String object is created.
- This immutability ensures that once a String is created, its value cannot be altered, providing safety in various operations.

2. StringBuilder:
