Explanation about printStackTrace() method

I do not understand the function of the printStackTrace() method, why and when we should use it. Any explanation is very much appreciated.

Thank you!

So printing the stack trace allows you to explain where the program is currently running. Methods end up on what is known as a call stack. This will probably grow into confusion quickly, as this is way later in the track, but here is a video I made about frames, feel free to stop watching that as soon as it gets confusing ;).

So printStackTrace is used to help you and other devs locate the problem when it happens.

Does that help?

It helps quite a lot actually, thank you! I'm sure by the time I'm done with the Java Application course, I'll have a good grasp :)
