Starting Java 7 courses you thru this language and a big collection of platform APIs in accordance with the subsequent desk of contents: bankruptcy  1: Getting all started with Java bankruptcy  2: researching periods and gadgets bankruptcy  three: Exploring complex Language good points bankruptcy  four: traveling Language APIs bankruptcy  five: amassing items bankruptcy  6: traveling extra software APIs bankruptcy  7: developing and Enriching Graphical person Interfaces bankruptcy  eight: Interacting with Filesystems bankruptcy  nine: Interacting with Networks and Databases bankruptcy 10: Parsing, growing, and remodeling XML files bankruptcy eleven: operating with net prone 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: functions Gallery bankruptcy 1 introduces you to Java and starts off to hide the Java language by means of concentrating on primary strategies corresponding to reviews, identifiers, variables, expressions, and statements. bankruptcy 2 maintains to discover this language by way of proposing all of its positive aspects for operating with periods and items. You know about beneficial properties on the topic of category statement and item production, encapsulation, details hiding, inheritance, polymorphism, interfaces, and rubbish assortment. bankruptcy three specializes in the extra complex language good points with regards to nested sessions, programs, static imports, exceptions, assertions, annotations, generics, and enums. extra chapters will introduce you to the few positive aspects now not coated in Chapters 1 via three.   bankruptcy four mostly strikes clear of overlaying language positive aspects (although it does introduce category literals and strictfp) whereas targeting language-oriented APIs. You know about Math, StrictMath, package deal, Primitive kind Wrapper sessions, Reference, mirrored image, String, StringBuffer and StringBuilder, Threading, BigDecimal, and BigInteger during this bankruptcy.   bankruptcy five starts off to discover Java's application APIs through focusing mostly at the Collections Framework. despite the fact that, it additionally discusses legacy collection-oriented APIs and the way to create your personal collections.   bankruptcy 6 maintains to target application APIs through offering the concurrency utilities in addition to the gadgets and Random sessions.   bankruptcy 7 strikes you clear of the command-line person interfaces that seem in prior chapters and towards graphical person interfaces. You first know about the summary Window Toolkit starting place, after which discover the Java origin periods when it comes to Swing and Java second. Appendix C explores Accessibility and Drag and Drop. bankruptcy eight explores filesystem-oriented I/O when it comes to 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 help by way of first featuring an advent to XML (including DTDs and schemas). It subsequent explores the SAX, DOM, StAX, XPath, and XSLT APIs. It even in short touches at the Validation API. whereas exploring XPath, you stumble upon namespace contexts, extension capabilities and serve as resolvers, and variables and variable resolvers. bankruptcy eleven introduces you to Java's help for SOAP-based and RESTful net providers. as well as supplying you with the fundamentals of those internet provider different types, bankruptcy eleven offers a few complex subject matters, akin to operating with the SAAJ API to speak with a SOAP-based internet carrier with no need to depend on JAX-WS. you'll take pleasure in having discovered approximately XML in bankruptcy 10 sooner than diving into this bankruptcy.   bankruptcy 12 is helping you set to exploit the various wisdom you could have accrued in earlier chapters through exhibiting you ways to exploit Java to jot down an Android app's resource code. This bankruptcy introduces you to Android, discusses its structure, indicates you ways to put in useful 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 aid for dynamically typed languages. Appendix C introduces you to extra APIs and structure themes: Accessibility, ByteArrayOutputStream and ByteArrayInputStream, classloaders, Console, machine, Drag and Drop, Dynamic structure, Extension Mechanism and ServiceLoader, dossier Partition-Space, dossier Permissions, Formatter, snapshot I/O, Internationalization, Java local Interface, NetworkInterface and InterfaceAddress, New I/O (including NIO.2), PipedOutputStream and PipedInputStream, personal tastes, Scanner, safety, clever Card, Splash monitor, movement Tokenizer, StringTokenizer, SwingWorker, process Tray, Timer and TimerTask, instruments and the Compiler API, Translucent and formed Window, and XML electronic Signature. Appendix D offers a gallery of important functions that show numerous facets of Java. regrettably, there are limits to how a lot wisdom might be filled right into a print publication. for that reason, Appendixes A, B, C, and D aren't integrated during this book's pages. as a substitute, 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 ( Appendixes C and D are bundled with their respective code documents on my site at Appendixes C and D are "living records" in that i will 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 technique Invocation and Corba, robotic, Runtime and strategy, Swing Timer, and plenty of different APIs/architecture subject matters (including a whole journey of Swing components). after all, it's going to take time to jot down approximately those subject matters so do not anticipate them all to seem right now -- they are going to slowly emerge in coming months (although smaller themes akin to robotic will emerge a lot faster). What you’ll study the complete Java language, together with Java 7-specific beneficial properties similar 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 corresponding to the Fork/Join Framework, items, JLayer, and NIO.2  a variety of Java 7 instruments, beginning with the javac compiler and java software launcher the right way to create person interfaces, operating with internet providers, and an entire lot extra the fundamentals of having all started with Android app development   Who this booklet is forThis publication pursuits the subsequent teams of builders: novices, expert (to some extent) in different programming languages yet without past publicity to Java Intermediate Java builders, expert within the basics of Java sooner than Java 7 and looking out to extend their realizing of Java 7 language/API alterations All builders taking a look past average 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 getting to know periods and items Exploring complex Language beneficial properties traveling Language and application APIs amassing items traveling extra software APIs growing and Enriching Graphical person Interfaces Interacting with Filesystems Interacting with Networks and Databases Parsing, growing, and remodeling XML records operating with net prone Java 7 Meets Android

Sample text

Listing 1-1. "); ŠŠŠ} } Listing 1-1 declares a class named HelloWorld that provides a framework for this simple application. It also declares a method named main within this class. When you run this application, and you will learn how to do so shortly, it is this entry-point method that is called and its instructions that are executed. The main() method includes a header that identifies this method and a block of code located between an open brace character ({) and a close brace character (}). As well as naming this method, the header provides the following information: public: This reserved word makes main() visible to the startup code that calls this method.

For example, when declaring a variable, don舗t insert a meaningless comment such as // this variable is an integer. Multiline Comments A multiline comment occupies one or more lines of source code. This comment begins with the /* character sequence, continues with explanatory text, and ends with the */ character sequence. Everything from /* through */ is ignored by the compiler. The following example demonstrates a multiline comment: static boolean isLeapYear(int year) { ŠŠŠ/* ŠŠŠŠŠŠA year is a leap year if it is divisible by 400, or divisible by 4 but ŠŠŠŠŠŠnot also divisible by 100.
