So I'm fairly new to object orientated Java programming and our teacher wants us to creat a rectangle, and any other 5+ Sided shape and my rectangle and that shape are very messed up.. I'm not sure what order to put my points in, so if someone can help that would be great. The rectangles code and how it looks are here:

And the other 5+ sided (real known shape)

thank you for any help!

In general, you should define a polygon by defining the points clockwise or counterclockwise. According to the API, a line segment will form between the last point and the first, so you have to take that into account.

Alright. I kind of get that, anyway you know what I can do to my code to make it work correct. I'll change my points to clockwise.

Make the last y-coordinate be yPosition.

I inputted the data into a very old program of mine and the following came out that SHOULD make it work:

50 0
75 -15
100 0
100 8
75 15
50 8

Unfortunately, converting that back to code would take quite a bit of time.

Again, I'm not certain if the output is correct since I haven't tested it for a while, but the general goal is to form a "convex hull" in the way you form your polygon. Otherwise, it might have difficulty forming the correct polygon.
