Divelog errors

Question

Hi everyone.
I am trying to compile the Divelog.java file but seem to get the following two errors.
C:\>javac c:\divelog\Divelog.java
c:\divelog\Divelog.java:7: class DiveLog is public, should be declared in a file named DiveLog.java
public class DiveLog extends JFrame
^
c:\divelog\Divelog.java:63: cannot resolve symbol
symbol : class WebSite
location: class divelog.DiveLog
tabbedPane.addTab("Favorite Web Site", null, new WebSite(), "Click here to see a web site" );
^
2 errors
I have installed j2se in the following directory c:\j2sdk1.4.2
The Divelog files are located in the following directory c:\divelog\
(so for example my Divelog.java file is located in c:\divelog\Divelog.java
Please could anyone help me with this problem, all the dive log files are correct, as i have checked several times.
Any help would be very much so aprreciated
