String is immutable, while StringBuilder is mutable and more efficient for concatenating strings.

• String is immutable, meaning its value cannot be changed once it is created.

• StringBuilder is mutable, allowing for modifications to the string without creating a new object.

• StringBuilder is more efficient for concatenating multiple strings as it does not create new objects each time.

• Example: String str = "Hello"; StringBuil
