How to call one function among many other functions randomly in Java ?

Answer 1

If the functions/methods were in different objects that inherited from the same class and you were allowed to use/override the same method name in the objects, you could probably store the objects in a collection like an array, get a random array index number and call the corresponding object's method, thereby calling a random/different method each time.

Answer 2

what do you exactly mean? you can call a function by jusr writing the functions name with (); e.g. myfunction();
