What's the difference between ClassLoader.getSystemResourceAsStream and ClassLoader.getResourceAsStream ??

getSystemResource() will only consult the "system ClassLoader", while getResource() will consult the ClassLoader the method is called on. The system ClassLoader is the "built-in" one, the one that loads classes from the CLASSPATH when an application starts up.
No Java programmer should miss reading Ted Neward's two excellent articles on ClassLoaders here and here.

So then all of my classes that I created in a single application should have the same classloader?

"Should" meaning "will, generally" or "should" meaning "it is good practice to?" The former, yes. The latter, not especially. If you need multiple ClassLoaders, then they're a good thing. If you don't, then you don't, and that's fine too.
Anyway, the answer to your question is that they will, in general, if you don't do anything special -- i.e., if you don't create your own class loader.
