The cover theme for the DEITEL

HOW TO PROGRAM SERIES emphasizes social consciousness issues such as
going green, clean energy, recycling, sustainability and more. Within the text, in addition to conventional program-
ming exercises, we’ve included our Making a Difference exercise set to raise awareness of issues such as global
warming, population growth, affordable healthcare, accessibility, privacy of electronic records and more. In this
book, you’ll use Java to program applications that relate to these issues. We hope that what you learn in
Java How to Program, 9/e will help you to make a difference.
Night at the Niagara Falls—Ontario and New York
The Niagara Falls waterfalls straddle the border between Ontario, Canada and upstate
New York in the United States. Horseshoe Falls is located on the Canadian side, and
American Falls and Bridal Veil Falls are on the U.S. side.
The Niagara Falls are an awe-inspiring, world-class tourist attraction, and a
significant source of hydroelectric power. On average, nearly four million cubic feet
of water falls over the crest line each minute. The U.S. and Canada harness the natu-
ral energy from Niagara Falls to generate clean, inexpensive electricity. The first
hydroelectric generating station on the Niagara River was built in 1881. Its electricity
powered local mills and street lights. The Niagara Redevelopment Act, passed by
the U.S. Congress in 1957, gave the New York Power Authority the right to develop
the U.S. Niagara River hydroelectric power plants. The Niagara Falls hydroelectric project began operating in 1961.
Up to 375,000 gallons of water per second is diverted from the river through conduits to the power plants. The
water spins turbines that power generators that convert the mechanical energy into electrical energy. Today,
the project generates 2.4 million kilowatts, which can power 24 million 100-watt light bulbs simultaneously. For
