A subset is a section of the collection that finds everything that starts with the first parameter and up until the second one. So here we are using Character.MAX_VALUE anything between A to Z (more or less there are more characters up in there, like smiley faces and icons).

That make sense?

Sorry @Craig Dennis but I dont get it...

So what is the second parameter? Since the Character.MAX_VALUE = '?' then our second parameter is "Java?" ?
