Introduction: Core Java Programs Pdf

What’s It All About?
Beginning Core Java Programs Pdf, You’ve probably used a computer to do word processing. Type a letter, print it out and then send the printout to someone you love. If you have easy access to a computer, then you’ve probably surfed the Web. Visit a page, click a link, and see another page. It’s easy, right?
Well, it’s easy only because someone told the computer exactly what to do. If you take a computer right from the factory and give no instructions to this computer, the computer can’t do word processing, the computer can’t surf the Web, it can’t do anything. All a computer can do is follow the instructions that people give to it.
Now imagine that you’re using Microsoft Word to write the great American novel, and you come to the end of a line. (You’re not at the end of a sentence, just the end of a line.) As you type the next word, the computer’s cursor jumps automatically to the next line of type. What’s going on here?

A Few Lines in a Computer Program

if (columnNumber > 60) {
wrapToNextLine();
}
else {
continueSameLine();
}

If the column number is greater than 60,
then go to the next line.
Otherwise (if the column number isn’t greater than 60),
then stay on the same line.
