Create and import Java library in Eclipse

Question

I have seen similar questions on SO and I'm just not getting it. I have a bunch of Java classes I need to import as a library. How do I make the jar file, save it in the right place, then tell Eclipse to import the jar file?

The classes I want in my library are here: StdIn library code

and this is the java code I want to import the library into: Sattolo algorithm code

There is a further library I would need to import to make the Sattolo algorithm run, but once I get the general idea...

I am a very, very new Java coder, so please be patient with me not understanding what must seem very basic.
