Java APIs

I am new to java and whenever I try to compile this is the error I get:

Error : Invalid path, \bin\javac.exe -classpath" C:\Documents and Settings\comp\Desktop" -d "C:\Documents and Settings\comp\Desktop" "C:\Documents and Settings\comp\Desktop\Wendy.java"

This is a file I directly copied off the internet that refers class Wendy and is called Wendy.java I am using jcreator as my compiler.

How can I actually compile the file???
