I have used getMethods but I end up getting a lot of methods from the Object and Class superclasses with parameters.įor example the following code that I have written: import .* īufferedReader reader = new BufferedReader(new InputStreamReader(System. Reflection gives developers the flexibility to inspect and determine API characteristics at runtime, instead of compile time. The problem I am having has to do with the following sentence: "list of the public methods that do not specify a parameter". Public variables with their values and allow the user to choose a Afterwards, the program should again show the Program should let the user choose a method and execute that method on Names and values of the public variables of the created object, andĪlso a list of the public methods that do not specify a parameter.

It allows us to inspect the elements of a class such as fields, methods or even inner classes, all at runtime. We assume that the class hasĪ constructor without any parameters.

Both methods accept a String argument and return a String as the result. It has two static methods, one public and one private. That class and creates an instance of it.
