Methods inherited from class java.security.BasicPermission:

Methods	Description
equals(Object obj)	It checks whether the two BasicPermission objects are equal or not.
getActions()	It returns the actions in String format, which is currently an empty string as there is no action for ReflectPermission.

            SecurityManager securityManager
                = System.getSecurityManager();
            if (null != securityManager) {
                securityManager.checkPermission(
                    new ReflectPermission(
                        "suppressAccessChecks"));
            }
