9. String Handling
Strings are sequences of characters that serve as a primary datatype in programming, particularly in Java. They enable the storage and manipulation of textual data, with a variety of operations such as length calculation, character access, and concatenation. Understanding string handling is essential for effective user input processing, message display, and data representation in applications.
