Question

I have function A, function B, and function C

I am trying to call one of these function randomly (A or B or C) from Main.

How can i go about doing it?

Can i put the functions in an arraylist called FunctionList

Then do the following?

int x = (int)(Math.random() * Functionlist.size());
FunctionCall = FunctionList.get(x) 

Answer 1

If the number of functions is small, the easiest way would be a switch,

switch((int)(Math.random()*NUM_FUNCTIONS) {
    case 0:
        functionA();
        break;
    case 1:
        functionB();
        break;
  //  ...
}
