Typoon Ondoy
On September 26,2009, Typhoon Ondoy brought a month's worth of rainfall to Metro Manila
and nearby areas in just a few hours, causing severe flooding which resulted int eh loss
of many lives and the displacement of hundreds of thousands of people. Areas under
Storm Signal No.2 included:Aurora,Quirino,Nueva Vizcaya, Nueva Ecija,Pangasinan, Tralac,
Zambales,Pampanga, bulacan, Rizal,Northern Quezon, and Polillo Island.The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAG-ASA)
has come up with a measure to classify typhoons based on wind speed (in kph):
Tropical depression have wind speeds of 30 to 46 kph (inclusive)
Tropical storms have wind speeds between 47 kph and 89 kph (inclusive)
Typhoons have wind speeds between 90 kph and 183 kph (inclusive)
Super Typhoons have wind speeds greater than 183 kph

Java Tuts site for Beginners to become Experts!

from the source(creators of java)
  http://java.sun.com/docs/books/tutorial/
others:
http://home.cogeco.ca/~ve3ll/jatutor0.htm

But its better if you read books about java.
Authors like Gosling are the best!
Or don't hesitate to approach me through the net
or meet me in person so that i could simplify further what the sites or books are talking about. I love teaching because it also enhances my expertise in java programming
