Описание: Chapter One considers some of the classes of the java.io package. Java defines input and output (I/O) in terms of classes known as streams. Streams provide system input and output in a way that isolates the developer from the details about how an operating system provides access to system resources for the purposes of I/O. Streams are not required for input and output when a graphical user interface (GUI) is used to capture and display information in an application. Graphical user interface design is examined in Chapter Three.

Chapter Two examines some of the classes of the Java Collections Framework in order to explore more flexible data structures than the humble array.

Constructing a user interface (UI) is one of the most rewarding features of application development using Java; it is highly creative and gives the developer the opportunity to work very closely with users to develop the UI that suits their needs. In this chapter, we will find out how user interfaces are constructed.

The use of the Thread class is often regarded as a relatively advanced topic for a beginners’ guide to Java. However the reader may recall, from Chapter Three, that a Swing GUI executes in its own thread of execution. This is an outcome of the fact that the Java Virtual Machine allows an application to have multiple threads of execution running concurrently. Despite the relative advanced nature of threads (of execution), it is clear from a study of Chapter Three that the reader should be aware of the fundamental concepts associated with threads in Java applications. Chapter Four briefly examines how more than one task can be carried out concurrently in Java programmes by means of threads.Дооформил B62
