Getting an error when running my program but it compiles.

Question

Hey guys, I'm having a problem running the program. Everything compiles correctly, but then I get the error code linked below. Everything I think is correct here. Any ideas? I posted CinReader as well in case you wanted to try compiling and running it yourself.
Thanks

Ok, here's what I did using the JSE 8.1 IDE.
1) I copied your code into a .java file named "TextShuffleGame".
It generated about half a dozon errors.
There are three classes in the program:
TextShuffleLevel
TextShuffleGame
CinReader
Each of these classes is declared "public" and I got the same error message on each one:
"class ... is public, should be declared in a file name ... .java"
so, I...
2) tried changing them to "private".
It then said: "modifier private not allowed here".
so, I...
3) deleted the modifiers for these three classes and left them as just class. No errors.
The next two errors had to do with the two import statements:
"import java.io.*;" and "import java.util.*;".
It said: "'class' or 'identifier' expected" for both. So, I...
4) moved them to the top of the source file.
Didn't help at first. So, I...
5) fiddle around with them a bit.
I tried "java.io;" and "java.util;" and then "java.*;" by itself. Still got errors. So, I put them back as you had them and for some mysterious reason, my editor decided they were fine. oO
This also corrected the last errors in the "CinReader" class. Here is the error-free code I now have in my "TextShuffleGame.java" file:
