![]() ![]() The above is true even if trying to access the variable from a subclass. Using Java Reflection we can inspect a class, interface, enum, get their structure, methods and fields information at runtime even though that class is not. Field field Class.forName (''). The reflection API is build around the operator on jobjRef-class objects that allows to access Java attributes and call object methods. If the method is static, there is no object, so we set the first. IllegalAccessException if this Method object is enforcing Java language access control and the underlying method is inaccessible. ![]() This method look for the field in the specified class reference and then in the super interfaces and then in the super classes. The first argument to invoke( ) is the object on which we would like to invoke the method. In the below example, we will access private fields, methods and constructors of Dumm圜lass in another class “ ReflectionExample3“. This is true for static variables as well. Reflection API also provides method to get specific public field of a class through getField () method. By default private fields, methods and constructors are not accessible but using java reflection API setAccessible(true) on the instance of Field, Method and Constructor, we can access those. The Java Reflection API has always had a huge encapsulation hole in the form of a method called setAccessible (). ![]()
