C PROGRAMMING FOR ABSOLUTE BEGINNERS PDF

Let’s face it. C++, ASP, and Java can be a little intimidating. But now they don’t have to be. The for the absolute beginner series gives you a fun, non-intimidating introduction to the world of programming. Each book in this series teaches a specific programming lang[r]

Summary
This chapter is arguably one of the most important chapters to understand. Java is an object-oriented programming language, and every Java program you write reflects this fact. In this chapter, you learned how to define a class. You learned about instance and class variables and m[r]

}
The Card class represents playing cards in terms of an actual value and a face value. The actual value, stored in actualValue , is intended to be some point value associated with the game the Card is used in. Its value is not restricted. The face value, stored in the faceValue variable, is t[r]

The Canvas Component
A Canvas is a blank rectangular area primarily used for displaying graphics or for capturing user events. The CanvasTest application creates four Canvas objects and displays them in the frame. One important thing to note is that CanvasTest extends Canvas . It ov[r]

The GridBagLayoutTest application lays out more components and uses more GridBagConstraints fields to lay them all out. There are eight Button objects— b1 , b2 , b3 , b4 , b5 , b6 , b7 , and b8 —and one TextArea object— ta . In this application, I add b1 without changing any of the constr[r]

Next, you declare jill and happily set its instance variables to values that differ from jack ’s, comfortable with the fact that jack remains unaffected. That is, until you mess with jill ’s vacation days. jill.vacationDays is jack.vacation- Days is Employee.vacationDays . Changing the state[r]

Counting Backwards
So far, every for loop you’ve encountered counts forwards, but you can also write a for loop in such a way that it counts backwards. You might want to do this in your Java programs in order to perform quicker array searches. For example, if you had an ar[r]

means that the lower limit, 0.0, is included as a possible value, whereas exclusive
means that 1.0, as the upper limit, is only a cap and is not a possible value. Another way to state this is that the range of possible values are all the values that are greater than or equal to 0.0 and less than[r]

and less than 0.3751 . Of course, the acceptable range will vary depending on how accurate the value must be.
You can also test for inequality by using the not-equal-to operator ( != ). This oper- ation will return true if the operands on either side are not equal to each other. It is the[r]

Depending on what the symbol is, it will draw a shape, a string, or an image in the cell. Also, to make it easier for the users to distinguish the cells they are currently working with, a red border appears around the cell when the cell is active but doesn’t have a match yet. If the cell has[r]

Drawing Ovals
Drawing ovals is similar to drawing rectangles. In fact the arguments to the methods that render the ovals specify the rectangular bounds of the oval. There are two methods for rendering ovals. The drawOval(int x, int y, int width, int height) method draws the outline of an[r]

The Project: The Block Game
The Block Game is similar in concept to the well-known Tetris game, owned by the Tetris Company, and originally developed by Alexey Pajitnov. The Block Game project in this book is for learning purposes only and can’t truly compare to the actual Tetris game.

How Do Applets Work?
To create an applet, you have to subclass the Applet class. The Applet class is found in the java.applet package, which is quite small—just the Applet class and a few interfaces. Applets have a method called init() . Typically, operations that you perform in a construct[r]

With the Internet as widely used as it is today, one of the more exciting features of Java is its use as a tool for Internet development. You can embed Java right into a Web docu- ment by writing an applet and adding some HTML to include that applet. In this chapter, you learn all about app[r]

questions is the array that holds the questions that this applet will ask. answers is an array of characters that represents the answers to these questions. The sub- script of the questions array corresponds to the subscript of the answers array so that the answer to questions[2] , for ex[r]

This chapter concentrates on a computer’s short-term, or volatile, memory. Volatile memory loses its data when power is removed from the computer. It’s commonly referred to as RAM (random access memory).
RAM is comprised of fixed-size cells with each cell number referenced through an address. Pr[r]

The Concentration Game uses many of the techniques you learned about in this chapter. Essentially, the Concentration Game generates random numbers and displays them for a short period of time for the user to memorize. During the time the random numbers are displayed, the player[r]

You probably already see the benefit of using indentation for readability as the preceding pseudo code is difficult to read and follow. Without indentation in your pseudo code or actual program code, it is extremely difficult to pinpoint nested conditions.
