    A journey of This Book
    Chapter 1 provides an summary of the features of Java that set it except different programming languages. We clarify what the designers of the language got down to do and to what quantity they succeeded. Then, we provide a quick historical past of ways Java got here into being and the way it has evolved.

    In Chapter 2, we let you know how you can obtain and set up the JDK and this system examples for this publication. Then we advisor you thru compiling and working 3 common Java courses, a console software, a graphical software, and an applet, utilizing the obvious JDK, a Java-enabled textual content editor, and a Java IDE.

    Chapter 3 starts off the dialogue of the Java language. during this bankruptcy, we disguise the fundamentals: variables, loops, and easy features. when you are a C or C++ programmer, this is often delicate crusing as the syntax for those language gains is basically similar to in C. should you come from a non-C historical past similar to visible uncomplicated, you'll want to learn this bankruptcy carefully.

    Object-oriented programming (OOP) is now within the mainstream of programming perform, and Java is totally item orientated.

    Chapter 4 introduces encapsulation, the 1st of 2 primary development blocks of item orientation, and the Java language mechanism to enforce it, that's, sessions and strategies. as well as the foundations of the Java language, we additionally supply recommendation on sound OOP layout. eventually, we conceal the magnificent javadoc device that codecs your code reviews as a suite of hyperlinked web content. when you are conversant in C++, then you definitely can flick through this bankruptcy quick. Programmers coming from a non-object-oriented heritage should still anticipate to spend it slow gaining knowledge of OOP techniques prior to going additional with Java.

    Classes and encapsulation are just one a part of the OOP tale, and Chapter 5 introduces the opposite, particularly, inheritance. Inheritance permits you to take an current classification and adjust it in line with your wishes. this can be a basic procedure for programming in Java. The inheritance mechanism in Java is sort of just like that during C++. once more, C++ programmers can concentrate on the variations among the languages.

    Chapter 6 indicates you ways to exploit Java’s idea of an interface. Interfaces allow you to transcend the easy inheritance version of bankruptcy five. getting to know interfaces helps you to have complete entry to the ability of Java’s thoroughly object-oriented method of programming. We additionally conceal an invaluable technical function of Java referred to as internal sessions. internal sessions help in making your code cleanser and extra concise.

    In Chapter 7, we commence software programming in earnest. each Java programmer should still understand a section approximately GUI programming, and this quantity comprises the fundamentals. We exhibit how one can make home windows, tips to paint on them, how you can draw with geometric shapes, easy methods to layout textual content in a number of fonts, and the way to reveal images.

    Chapter 8 is a close dialogue of the development version of the AWT, the summary window toolkit. You’ll see the right way to write the code that responds to occasions like mouse clicks or key presses. alongside the way in which you’ll see the way to deal with easy GUI components like buttons and panels.

    Chapter 9 discusses the Swing GUI toolkit in nice element. The Swing toolkit enables you to construct a cross-platform graphical person interface. You’ll study all in regards to the different types of buttons, textual content elements, borders, sliders, record packing containers, menus, and conversation packing containers. despite the fact that, many of the extra complicated parts are mentioned in quantity II.

    Chapter 10 indicates you ways to set up your courses, both as purposes or applets. We describe the best way to package deal courses in JAR records, and the way to bring purposes over the net with the Java net begin and applet mechanisms. ultimately, we clarify how Java courses can shop and retrieve configuration details after they were deployed.

    Chapter 11 discusses exception dealing with, Java’s strong mechanism to accommodate the truth that undesirable issues can ensue to stable courses. Exceptions provide you with a good approach of isolating the conventional processing code from the mistake dealing with. in fact, even after hardening your software through dealing with all unheard of stipulations, it nonetheless may possibly fail to paintings as anticipated. within the moment 1/2 this bankruptcy, we offer you plenty of invaluable debugging suggestions. ultimately, we advisor you thru a pattern debugging session.

    Chapter 12 offers an summary of popular programming, an immense increase of Java SE 5.0. universal programming makes your courses more straightforward to learn and more secure. We convey you the way you should use robust typing and take away unpleasant and dangerous casts, and the way you could take care of the complexities that come up from the necessity to remain suitable with older models of Java.

    The subject of Chapter 13 is the collections framework of the Java platform. everytime you are looking to gather a number of gadgets and retrieve them later, you'll want to use a suite that's most suitable to your conditions, rather than simply tossing the weather into an array. This bankruptcy indicates you the way to use the traditional collections which are prebuilt to your use....

    Sample text

    You use this for a comment that will run from the // to the end of the line. '"); // is this too cute? When longer comments are needed, you can mark each line with a //. Or you can use the /* and */ comment delimiters that let you block off a longer comment. This is shown in Listing 3–1. Listing 3–1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. '"); } } Finally, a third kind of comment can be used to generate documentation automatically. This comment uses a /** to start and a */ to end. For more on this type of comment and on automatic documentation generation, see Chapter 4.

    We will have more to say about the use of braces when we talk about the various kinds of loops. For now, don’t worry about the keywords static void—just think of them as part of what you need to get a Java program to compile. By the end of Chapter 4, you will understand this incantation completely. The point to remember for now is that every Java application must have a main method that is declared in the following way: public class ClassName { public static void main(String[] args) { program statements } } C++ NOTE: As a C++ programmer, you know what a class is.

    For that reason, the initial specification of the Java virtual machine mandated that all intermediate computations must be truncated. The numeric community hated it. Not only can the truncated computations cause overflow, they are actually slower than the more precise computations because the truncation operations take time. For that reason, the Java programming language was updated to recognize the conflicting demands for optimum performance and perfect reproducibility. By default, virtual machine designers are now permitted to use extended precision for intermediate computations.
