Thank you five years later this really did help me with my class

For people watching this video. Don't call the paint method with null in the parameter. That is wrong! When the window is created it automatically calls the paint method. Doing it the way this guy taught it will give you a nullpointereception. The tutorial is wrong. Yes it will work, but it throws an exception.

I highly appreciate this video, and other youtubers who take time out of their lives to make wonderful videos like these :)
Thanks to you, I aced my quiz! (Ok, my quiz is actually tomorrow, but I guarantee I will ace it)

The only line you need in main is Tutorial t = new Tutorial(); Putting t.paint(null); in effectively means you are trying to call the paint() method twice, as paint() is automatically called when you create the class object.

umm I get an error for importing java.awt.Graphics for some reason. Do I need to download it somewhere or what? I'm new to importing stuff and eclipse in general, but have been doing stuff in unity for 9 months.

I miswrote triangles. Am I missing something? He passed null in as a parameter for graphics, how tf did it not throw an exception, and how the actual heck did it work?

setSize(900, 800); and you'll see the rectangle

I feel like you don't know half of the things you are doing. It would be better if the explanations could be more in depth.
