The "java" command takes a class as an argument, not a file. Class names are
similar to file names, but without the ".class" part, so you should type:

   java ap1

There are coding conventions for Java that one should begin class or other
interface names with an upper-case letter, and (most) variable and method
names with a lower-case letter. Use single or compound words for names, such
as "class SomethingNifty"; each compound word part other than the first begins
with an upper-case letter for both classes and variables or methods. So you
should get in the habit, using your example, of naming a class like:

   public class Ap1

and you would invoke it with

   java Ap1

Later you will learn about packages, which would give you a command like:

   java com.lewscanon.SomethingNifty

Read the material at <http://java.sun.com/>, especially the tutorials.

Please follow up at comp.lang.java.help . Another good newsgroup is
comp.lang.java.programmer but it is somewhat more advanced.

Although the command to invoke a Java program is "java", the name of the
language is "Java". The language itself is very picky about upper- and
lower-case spelling, so it's a good idea to get in the habit of rigor about
letter case generally.
