The 3rd edition of the well known reference, Java in a short, covering important API of Java 1.2, including networking, security, input and output, and basic language and utility classes. Because the size of the Java 1.2 API, graphics and graphical user interface classes are now examined in the volume called Java Foundation Classes in a short, and server-side and enterprise programming are detailed in Java Enterprise in a short. This book intends to document quite a bit of Java, and easily managed with a wide range of Java programming in Part I, and API cataloging broken down by package in Part II. Sections for each class can be very informative, as in the discussion in chapter java.net Socket class, which includes how to instantiate a Socket object, getting I / O stream of objects that are instantiated, and how to change the behavior of the socket Keogh. - John Topics covered: Part I, "Introducing Java," provides extensive coverage of Java programming topics, including data types, syntax, classes, and objects; Java file structure inner classes, interfaces, packages, create and initialize objects, destroying objects and settlement ; input / output, cryptography, networking, security, threads, JavaBeans, javadoc, and the tools that come with Java 1.2 SDK. Part II, "Java API Quick Reference," includes chapters on the following Java packages: java.beans, java.beans.beancontext, java.io, java.lang, java.lang.ref, java.lang.reflect, java mathematics,. java.net, java.security, java.security.acl, java.security.cert, java.security.interfaces, java.security.spec, java.text, java.util, java.util.jar, java util.zip ,. javax.crypto, javax.crypto.interfaces, javax.crypto.spec, and the last chapter, which provides indices for classes, methods, and fields.
