You see how similar these two lines are? As a trained Java programmer, because of the capitalization I immediately think these are both static method calls, one on a class named "Names", and one on a class named "Collections". The fact that there is a class named "Names", and it doesn't actually have a method named "close()" is a source of great cognitive dissonance. It's a time waster, now, because I have to figure out what the heck is going on. If the variable name started with a lower-case letter, then I'd know it was a variable, and I'd first find out what type it was before trying to find any information about close().
Also, you're using the name "Names" twice, for two completely different things. One is the static class Names, and the other is for a local variable of type TextFileIn. This would be very confusing even if you weren't violating the name convention that Bear and Ernest are talking about. You should have different names for different things.
