True or False: A method can only return primitive data types.

A method in Java can return a variety of data types, not just primitive ones. This includes user-defined types such as objects and collections. When a method's return type is specified, it can be any valid data type in Java, including classes, interfaces, and arrays, in addition to primitive data types like int, char, and boolean.

For instance, if you define a method that returns an instance of a class, the method can then provide the caller with a fully formed object rather than a simple value. This allows for more complex data structures and functionalities, making Java a powerful object-oriented programming language.

The variety of return types enhances flexibility in programming, enabling developers to create comprehensive applications that can leverage both built-in and user-defined types effectively.
