Explanation:

Free functions or non-member functions in C++ do not require a class to be instantiated prior to their invocation.

Java provides a similar concept in terms of static methods. Static methods can be invoked without instantiating the object by prefixing the class name before the method name. For example:

Math.max()

Integer.parseInt()

String.valueOf()

Class.forName()
