ESSENTIAL JAVA FOR SCIENTISTS AND ENGINEERS (Enhanced Edition‪)‬

Computers have become an essential part of our everyday lives. Even if you don't use a computer for
writing letters, browsing the Internet, or playing games, you are using computers every time you draw
money from an ATM, use your cell phone, or phone automatic directory enquiries. A computer on its
own has no intelligence. All that a computer can do is follow a detailed set of instructions, so it has to be
programmed with these instructions for it to be useful. That's where the task of the programmer lies: in
writing programs to make computers useful to people. Every bit of software, from your wordprocessor,
to your web browser, was written by a programmer (or more likely, a team of programmers).
