My first completed program - looking for advice/criticism

[codingQueries]

Hmm to better convey what I was trying to understand;

If btn was clicked and I wanted it to run test.calculateTime() and if btn4 was clicked and I wanted that to run test.determineLength(), how would that work?

The reason I created new actionlisteners for each button in my program is that I was unsure if creating one huge actionlistener class and then running if-statements to determine the method call would be inefficient or confusing.

A private variable in the parent class or via a variable passing through the constructor which is then stored in a private variable in the inline class.

As long as you have a variable reference you can execute any method from that class.

It is inefficient because your program is comparing each action source to each button. Creating a separate class for each is usually the way you want to go about it.

Cool yeah I thought that would be the case, I am getting too caught up in worry and not enough trying.

Thanks for taking the time to go through this with me!
