Let C be the class or interface represented by this   {@code Class} object:<ol> <li> A union of methods is composed of: <ol type="a"> <li> C's declared public instance and static methods as returned by {@link #getDeclaredMethods()} and filtered to include only publicmethods.</li> <li> If C is a class other than  {@code Object}, then include the result of invoking this algorithm recursively on the superclass of C.</li> <li> Include the results of invoking this algorithm recursively on all direct superinterfaces of C, but include only instance methods.</li> </ol></li> <li> Union from step 1 is partitioned into subsets of methods with same signature (name, parameter types) and return type.</li> <li> Within each such subset only the most specific methods are selected. Let method M be a method from a set of methods with same signature and return type. M is most specific if there is no such method N != M from the same set, such that N is more specific than M. N is more specific than M if: <ol type="a"> <li> N is declared by a class and M is declared by an interface; or</li> <li> N and M are both declared by classes or both by interfaces and N's declaring type is the same as or a subtype of M's declaring type (clearly, if M's and N's declaring types are the same type, then M and N are the same method).</li> </ol></li> <li> The result of this algorithm is the union of all selected methods from step 3.</li> </ol>
 * @apiNote There may be more than one method with a particular nameand parameter types in a class because while the Java language forbids a class to declare multiple methods with the same signature but different return types, the Java virtual machine does not.  This increased flexibility in the virtual machine can be used to implement various language features.  For example, covariant returns can be implemented with  {@linkplain java.lang.reflect.Method#isBridge bridge methods}; the bridge method and the overriding method would have the same signature but different return types.
