Java .class file name does not match source file name

Question

I just set up JDK 7 on my PC running Windows 7 and created a hello world program called HelloWorldApp.java.

When I tried to run it, it said that it couldn't find the file. I looked in the directory and found the .class file, but it was named HelloWoldApp.class (note the missing r).

Why is this, and should I be concerned?

Did it really compiled fine? Did you at least get a compiler warning? — The Original Android

Check your source file. I bet you named the class HelloWoldApp inside.

I can't believe I didn't realize that, I'm very new to Java.

It works just fine for me.

You should probably be concerned if and only if you have double, triple, quadruple,..., and n-tuple checked that you didn't spell the name of the class incorrectly.

You may have reason to be concerned about your spelling.
