What does this line of code mean?

[Frankie Law]

I downloaded a game project online so I can see how other people code.
I decompiled a .class file and I found this line of code inside.  What does it mean?

InputStream var1 = (class$mikera$tyrant$Game == null?(class$mikera$tyrant$Game = class$("mikera.tyrant.Game")):class$mikera$tyrant$Game).getResourceAsStream("/version.txt");

I don't think you would get a reply for a random decompiled code. We folks might want to first understand if whatever you did is legal and ethical.
You might want to put some references here,  like say, it is open source and the company who wrote the game are okay for users to download the code, decompile it and understand it.
That said, if it is was truly open source, they would publish a git or src code in one of the sites.

Source code for this is available on GitHub.

OP: Please go through the source and see if you can find the original for that code. It is formatted even worse than code in an OCJP book and very difficult to read.
