Java volume I Fundamentals by Horstmann Cornell Core download free book online for IT

In late 1995, the Java programming language buret onto the Internet scene and gained instant celebrity status. The promise of Java technology was that it would become the universal glue that connects users with information, whether that information comes from web servers, databases, information providers, or any other imaginable source. Indeed, Java is in a unique position to fulfill this promise. It is an extremely solidly engi- neered language that has gained acceptance by all major vendors, except for Microsoft. Its built-in security and safety features are reassuring both to programmers and to the users of Java programs. Java even has built-in support that makes advanced program- ming tasks, such as network programming, database connectivity, and multithreading, straightforward. Since 1995, Sun Microsystems has released seven major revisions of the Java Develop- ment Kit. Over the course of the last eleven years, the Application Programming Inter- face (API) has grown from about 200 to over 3,000 classes. The API now spans such perse areas as user interface constaiction, database management, internationaliza- tion, security, and XML processing. The book you have in your hands is the first volume of the eighth edition of Core JavaTM. With the publishing of each edition, the book followed the release of the Java Development Kit as quickly as possible, and each time, we rewrote the book to take advantage of the newest Java features. This edition has been updated to reflect the features of Java Standard Edition (SE) 6. As with the previous editions of this book, we still target serious programmers who want to put jam to work on real projects. We think of you, our reader, as a programmer with a solid back- ground in a programming language other than Java, and we assume that you don’t like books filled with toy examples (such as toasters, zoo animals, or „nervous text”). You won’t find any xix of these in this book. Our goal is to enable you to fully understand the Java language and library, not to give you an illusion of understanding. In this book you will find lots of sample code that demonstrates almost every’ language and library feature that we discuss. We keep the sample programs purposefully simple to focus on the major points, but, for the most part, they aren’t fake and they don’t cut corners. They should make good starting points for your own code. We assume you are willing, even eager, to learn about all the advanced features that Java puts at your disposal. For example, we give you a detailed treatment of:

• Object-oriented programming

• Reflection and proxies

• Interfaces and inner classes

• The event listener model

• Graphical user interface design with the Swing UI toolkit

• Exception handling

• Generic programming

• The collections framework

• Concurrency
