ObjClassFieldsReflection.AccessFieldsUsingReflection(new Actor()) getFields() returns an array containing Field objects reflecting all the accessible public fields of the class or interface represented by this Class object.The. Reflection allows programmatic access to information about the fields, methods and constructors of loaded classes, and the use of reflected fields, methods, and constructors to operate on their underlying. or if you want to get all fields with all visibility, we can.
