ReflectPermission class extends BasicPermission class. It is a “named” permission i.e it contains a name but no action. It may implement actions on top of BasicPermission, if desired. It is used to get information about the behaviour of Constructors.

Constructors Description
ReflectPermission(String name) It is used to create a ReflectPermission with the specified name.
ReflectPermission(String name, String action) It is used to create a ReflectPermission with the specified name and action.

Methods inherited from class java.security.BasicPermission:

Methods Description
equals(Object obj) It checks whether the two BasicPermission objects are equal or not.
