10. Arrays and Strings
Arrays in Java are structures that efficiently store collections of elements of the same type, providing ease of access through indexing. Strings, being immutable sequences of characters, are vital for handling textual data. Both data types offer various operations for manipulation, such as sorting and conversion, making them essential tools in programming.
