Make an array of methods to call

Question

I have some classes on my code and based on the click of the listview i want to run the selected class. What I mean is that if a user clicks on position 0 I want to run method GoToTown(). I have more than 40 methods so if I do it with if / elseif it would be really bad. I have a custom adapter for the listview so probably I could use it somehow?

Is there some way I could pass an array to do it?

You should include some code in your question to demonstrate what you want to do — OneCricketeer, Mar 06 '16 at 16:53
I'm sorry you are right Methods. (I'm just kind of new in development) — marduc812, Mar 06 '16 at 16:56

@marduc812 yes, you can also check this pattern: https://en.wikipedia.org/wiki/Command_pattern — dieter, Mar 06 '16 at 17:03

Instead of using 40 different methods, use only 1 (the one which should get the listview result and call one of the 40 methods). And then you should have a switch inside it:

// "number" is the number if the item clicked in the list
switch (number) {
case 0: // First item was clicked, counting starts from 0
    // Put some code here
    break;
case 1: // Second item...
    // Other code
    break;
// Etc.
default: // You did not define a "case" for a number, default gets executed
    // Code here
}
