Question

Good day.

I have a class that I’m going to use to generate math exercises for training purposes. The class is made of a series of method, each one of them generates one type of exercises.

I’d like then to make a method that generates one random exercise of a random type. To do this I thought to store the methods name in an array an call a random entry.

So far so good.

Since in the future I’m going to add methods to generate new exercise types, I’d like to know if there is a way to generate dynamically the array of the methods: once the class is loaded, the constructor will check the methods available and store their name in an array.

Is that possible? And, if so, how?

Answer 1

Instead of storing the names you can store Method proxies

Method[] methods = getClass().getDeclaredMethods();

You need to go through these are ignore any method you add which are not tests.
