Q:

Cannot compile a Java program command-line

I tried the following in cl:
javac Main.java
The shell gives an error that "javac" is not a recognized command.  I know for a fact I have the Java Platform installed.  What could be wrong?
(I use "cd" to set the directory first)

A:

javac is most likely not on the PATH, and you must give the full path in your command.
