"Hi, Amigo!"

"I can teach you my special skill: avoiding unnecessary work."

"Hmm. I like how this is starting."

"Remember, it's impossible to know everything. And it's not necessary. But, if you can quickly find the information you need, then you're golden."

"Java is growing so quickly, because Java programmers use each other's work. The Internet has millions of Java libraries that are well written, debugged, documented, and license free. Use them."

"There are hundreds of websites for programmers, where more experienced programmers help beginners and those who are less experienced. Use them."

"Anything you may want to write, somebody else has already written. Well, maybe not everything, but 90-95 percent, for sure."

"Whoa."

"I want you to always remember two things:"

1. Programming started over 50 years ago. Java is almost 20 years old.

99% of the code you need has already been written.

2. Before you write anything from scratch, search the Internet. Most likely, someone has needed it before and already solved the problem.

"So, we're going to learn how to 'google', i.e. search the Internet. As you might have guessed, 'googling' involves using the Google search engine."

"Other search engines will work too. But because programming is evolving most rapidly in Silicon Valley, Google will be our tool of choice."

"I will give you tasks where you need to find something using Google, so you'll have to learn how to search for things."

"But for now, we'll just start with some examples."
