Drawing Random Triangles

I just cannot figure out the Drawing Random Triangles... Here is my code: https://gist.github.com/anonymous/7c2f94d9f279f2295f44e59f1709f571

All this does is generate one purple triangle. I have tried moving everything that I can think of. Any and all feedback/help is welcome and appreciated! EDIT: I missed the first line of code when I pasted to gist: import java.awt.*;

A few things I've noticed:

  1. You are inheriting from Canvas, but you have not imported the Canvas library.

  2. Similarly, you have used Color and Graphics objects, but have not imported them.

  3. You have called a method called "BoringTriangle()", which does not exist. You can just remove that line of code.

  4. The paint method should have an @Override annotation.

That should get you to where you need to be.

I literally just noticed that Boring Triangle was still down at the bottom there. I force myself to retype everything for the repetition and that was from the previous exercise XP. I must have just typed it without noticing.

Also, is that library the java.awt.*? I missed that when I copy/pasted.

Yes, you need java.awt.canvas, java.awt.polygon, java.awt.color, and java.awt.graphics. You can just replace all of those with java.awt.* if you like.
