Starting Java 7 courses you thru this language and an immense collection of platform APIs in accordance with the next desk of contents: bankruptcy 1: Getting began with Java bankruptcy 2: getting to know sessions and gadgets bankruptcy three: Exploring complex Language beneficial properties bankruptcy four: traveling Language APIs bankruptcy five: amassing gadgets bankruptcy 6: traveling extra software APIs bankruptcy 7: growing and Enriching Graphical consumer Interfaces bankruptcy eight: Interacting with Filesystems bankruptcy nine: Interacting with Networks and Databases bankruptcy 10: Parsing, developing, and remodeling XML files bankruptcy eleven: operating with internet companies bankruptcy 12: Java 7 Meets Android Appendix A: options to workouts Appendix B: Scripting API and Dynamically Typed Language help Appendix C: Odds and Ends Appendix D: purposes Gallery bankruptcy 1 introduces you to Java and starts off to hide the Java language by way of targeting basic options resembling reviews, identifiers, variables, expressions, and statements. bankruptcy 2 maintains to discover this language through proposing all of its positive aspects for operating with periods and items. You know about positive factors relating to classification statement and item production, encapsulation, details hiding, inheritance, polymorphism, interfaces, and rubbish assortment. bankruptcy three makes a speciality of the extra complicated language beneficial properties regarding nested periods, applications, static imports, exceptions, assertions, annotations, generics, and enums. extra chapters will introduce you to the few good points now not lined in Chapters 1 via three. bankruptcy four principally strikes clear of masking language positive aspects (although it does introduce type literals and strictfp) whereas concentrating on language-oriented APIs. You find out about Math, StrictMath, package deal, Primitive sort Wrapper periods, Reference, mirrored image, String, StringBuffer and StringBuilder, Threading, BigDecimal, and BigInteger during this bankruptcy. bankruptcy five starts off to discover Java's software APIs by way of focusing mostly at the Collections Framework. despite the fact that, it additionally discusses legacy collection-oriented APIs and the way to create your individual collections. bankruptcy 6 keeps to target application APIs via offering the concurrency utilities in addition to the items and Random periods. bankruptcy 7 strikes you clear of the command-line person interfaces that seem in prior chapters and towards graphical consumer interfaces. You first find out about the summary Window Toolkit origin, after which discover the Java beginning periods by way of Swing and Java second. Appendix C explores Accessibility and Drag and Drop. bankruptcy eight explores filesystem-oriented I/O by way of the dossier, RandomAccessFile, circulation, and writer/reader periods. New I/O is roofed in Appendix C. bankruptcy nine introduces you to Java's community APIs, corresponding to sockets. It additionally introduces you to the JDBC API for interacting with databases. bankruptcy 10 dives into Java's XML aid via first providing an creation to XML (including DTDs and schemas). It subsequent explores the SAX, DOM, StAX, XPath, and XSLT APIs. It even in brief touches at the Validation API. whereas exploring XPath, you come across namespace contexts, extension features and serve as resolvers, and variables and variable resolvers. bankruptcy eleven introduces you to Java's help for SOAP-based and RESTful net prone. as well as supplying you with the fundamentals of those internet carrier different types, bankruptcy eleven offers a few complex themes, reminiscent of operating with the SAAJ API to speak with a SOAP-based net carrier with no need to depend upon JAX-WS. you'll have fun with having discovered approximately XML in bankruptcy 10 sooner than diving into this bankruptcy. bankruptcy 12 is helping you set to take advantage of a number of the wisdom you have accumulated in past chapters via displaying you the way to exploit Java to write down an Android app's resource code. This bankruptcy introduces you to Android, discusses its structure, indicates you the way to put in precious instruments, and develops an easy app. Appendix A provides the suggestions to the programming routines that seem close to the tip of Chapters 1 via 12. Appendix B introduces you to Java's Scripting API in addition to Java 7's help for dynamically typed languages. Appendix C introduces you to extra APIs and structure subject matters: Accessibility, ByteArrayOutputStream and ByteArrayInputStream, classloaders, Console, computing device, Drag and Drop, Dynamic format, Extension Mechanism and ServiceLoader, dossier Partition-Space, dossier Permissions, Formatter, photo I/O, Internationalization, Java local Interface, NetworkInterface and InterfaceAddress, New I/O (including NIO.2), PipedOutputStream and PipedInputStream, personal tastes, Scanner, protection, clever Card, Splash monitor, flow Tokenizer, StringTokenizer, SwingWorker, procedure Tray, Timer and TimerTask, instruments and the Compiler API, Translucent and formed Window, and XML electronic Signature. Appendix D provides a gallery of important purposes that show quite a few points of Java. regrettably, there are limits to how a lot wisdom might be stuffed right into a print e-book. therefore, Appendixes A, B, C, and D aren't integrated during this book's pages. in its place, those appendixes are freely disbursed as PDF documents. Appendixes A and B are bundled with the book's linked code dossier on the Apress site (http://www.apress.com). Appendixes C and D are bundled with their respective code documents on my TutorTutor.ca site at http://tutortutor.ca/cgi-bin/makepage.cgi?/books/bj7. Appendixes C and D are "living files" in that i'm going to sometimes upload new fabric to them. for instance, I plan to extend Appendix C via additionally overlaying Java Naming and listing Interface, Java Sound, distant process Invocation and Corba, robotic, Runtime and technique, Swing Timer, and lots of different APIs/architecture issues (including a whole journey of Swing components). in fact, it is going to take time to write down approximately those themes so do not count on them all to seem straight away -- they're going to slowly emerge in coming months (although smaller subject matters resembling robotic will emerge a lot faster). What you’ll research the full Java language, together with Java 7-specific beneficial properties comparable to activate string, try-with-resources, ultimate rethrow, multicatch, and SafeVarargs an enormous collection of Java 7 APIs, starting with these APIs orientated towards the language itself, and together with Java 7-specific APIs similar to the Fork/Join Framework, gadgets, JLayer, and NIO.2 quite a few Java 7 instruments, beginning with the javac compiler and java software launcher easy methods to create consumer interfaces, operating with internet companies, and an entire lot extra the fundamentals of having begun with Android app development Who this publication is forThis e-book ambitions the next teams of builders: beginners, expert (to some extent) in different programming languages yet with out earlier publicity to Java Intermediate Java builders, expert within the basics of Java ahead of Java 7 and looking out to extend their figuring out of Java 7 language/API alterations All builders taking a look past common Java, who are looking to leverage Java 7 to create cellular apps through Android Even complex Java builders may possibly discover a few goods of curiosity desk of Contents Getting begun with Java learning periods and items Exploring complex Language good points traveling Language and software APIs gathering gadgets traveling extra application APIs growing and Enriching Graphical person Interfaces Interacting with Filesystems Interacting with Networks and Databases Parsing, growing, and reworking XML records operating with net companies Java 7 Meets Android

Beginning Java 7 would have taken many more months to complete if I didn9t leverage its predecessor. ) Don9t get the idea that Beginning Java 7 is a rehash of Learn Java for Android Development舑it9s not. In those portions of Beginning Java 7 where I9ve stolen heavily from its predecessor, there typically are numerous changes and additions. For example, I9ve rewritten parts of the exceptions and generics content that appear in Chapter 3; I did so to introduce new Java 7 features and to provide better coverage of difficult topics.
The Java ME (Mobile Edition) SDK is used to create applications known as MIDlets and Xlets. MIDlets target mobile devices, which have small graphical displays, simple numeric keypad interfaces, and limited HTTP-based network access. Xlets typically target television-oriented devices such as Blu-ray Disc players. The Java ME SDK requires that the JDK also be installed. I don舗t discuss MIDlets or Xlets. The Java EE (Enterprise Edition) SDK is used to create component-based enterprise applications.
