Methods

A method contains executable code which may be invoked. Methods are inherited and in non-reflective code behaviors such as overloading, overriding, and hiding are enforced by the compiler. In contrast, reflective code makes it possible for method selection to be restricted to a specific class without considering its superclasses. Superclass methods may be accessed but it is possible to determine their declaring class; this is impossible to discover programmatically without reflection and is the source of many subtle bugs.

The java.lang.reflect.Method class provides APIs to access information about a method's modifiers, return type, parameters, annotations, and thrown exceptions. It also be used to invoke methods. These topics are covered by the following sections:
