login page and -Xlint message on compilation

i have a login page which ought to call up another page once the password entered corresponds with the data on the table in the database.

I tried to compile the code in the file Enter.java and i got the following message on the command prompt:

NOTE: Enter.java uses or overrides a deprecated API.

NOTE: Recompile with -Xlint:deprecation for details.

WHAT DOES IT MEAN TO RECOMPILE WITH -Xlint?

Any idea what this is about and how to circumvent it?
