The above code is displayed when I run it

Where is the definition for the Library class? It looks like it needs some files to execute properly.
Do you have instructions for how to use the Library class?

It looks like the Library class uses some non-java code. Do you have instructions on how to use the Library class?

If you don't know how to use the Library class and it's giving you a problem, I recommend that you comment it out of your code so the java part of your program will execute without problems.

Put // in the first column of the statements that use the Library class to make those statements a comment.
