Send value return value

Question

Oke so I have to work in Processing for my school assignment and I have a question. This is my code:

tempArray.add(new TreeDot(randomBranchDotX(randomX),randomBranchDotY(randomY),strokeThickness));

int randomBranchDotX(int _randomX)
{   
 ArrayList tempArray = (ArrayList) branchList.get(i);
 TreeDot temp = (TreeDot) tempArray.get(tempArray.size() -1);
}

I am returning _randomX but is it als possible to send it so i can use it as the array index and then return _randomX. I hope my question is clear because I had trouble explaining it. Thank you in advance!

You can pass as many parameters/arguments into your function as you like and use them as such:

int randomBranchDotX(int _randomX, int i)
{   
  ArrayList tempArray = (ArrayList) branchList.get(i);
  TreeDot temp = (TreeDot) tempArray.get(tempArray.size() -1);
  return _randomX;
}

Use of this function will require two input paramaters for example:

randomBranchDotX(randomX, avaluefori)

Although, based on your example, you're calling randomBranchDotX in a way where the return value isn't utilised....

EDIT: I wrote it wrong lol, you are using the return value, just that your initial code didnt return a value is what I was meant to say. Sorry for the confusion.
