Hello there!

How would you guys track two (or multiple) average points instead of one as shown in the Shiffman video below? I have tried a lot of things but cannot seem to find the solution!

Thousand times thanks to whomever can help me!

In general you’re probably looking for arrays or ArrayLists.

Shameless self-promotion:

Thank you for your response. You have a cool website and I’m going to try to look through it. However, I realize that I can use Arrays or ArrayLists to store the multiple average points. The question is how I can start tracking multiple points? How do I tell my program that if has found one average point that is to start looking for another, in a different location even when it might be close by?
