Other Java Random Maze Generator

[StrangePickle 234 iPhone 11 16.7]

Hello guys!

It has been a while since I posted a topic, and I have become inactive.

I would just like to share part of my final project in my AP Computer Science class.

My teacher told my class to create any game we wanted using java eclipse and only the console.

So I created a randomly generated maze, it is not complete yet, I still have to add some functions n crap.

But basically you start off with 200 points and lose 5 points every step you take, type "u" to go up, "d" to go down, "r" to go right, and "l" to go left. (Pretty basic)

If you run the script in eclipse it is self explanatory. I put so many notes in the script so if you want to follow/learn the code you can try to.

Welp here it is:
