Starting Java 7 publications you thru this language and a major collection of platform APIs in line with the subsequent desk of contents: bankruptcy  1: Getting began with Java bankruptcy  2: learning periods and items bankruptcy  three: Exploring complex Language positive aspects bankruptcy  four: traveling Language APIs bankruptcy  five: accumulating gadgets bankruptcy  6: traveling extra application APIs bankruptcy  7: growing and Enriching Graphical person Interfaces bankruptcy  eight: Interacting with Filesystems bankruptcy  nine: Interacting with Networks and Databases bankruptcy 10: Parsing, developing, and reworking XML records bankruptcy eleven: operating with internet providers bankruptcy 12: Java 7 Meets Android Appendix A: suggestions 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 to hide the Java language by way of concentrating on basic strategies comparable to reviews, identifiers, variables, expressions, and statements. bankruptcy 2 maintains to discover this language by means of featuring all of its positive aspects for operating with periods and items. You find out about gains on the topic of classification announcement and item production, encapsulation, info hiding, inheritance, polymorphism, interfaces, and rubbish assortment. bankruptcy three specializes in the extra complex language positive aspects with regards to nested sessions, applications, static imports, exceptions, assertions, annotations, generics, and enums. extra chapters will introduce you to the few good points no longer coated in Chapters 1 via three.   bankruptcy four mostly strikes clear of masking language beneficial properties (although it does introduce classification literals and strictfp) whereas targeting language-oriented APIs. You know about Math, StrictMath, package deal, Primitive kind Wrapper periods, Reference, mirrored image, String, StringBuffer and StringBuilder, Threading, BigDecimal, and BigInteger during this bankruptcy.   bankruptcy five starts to discover Java's software APIs by means 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 software APIs through featuring the concurrency utilities in addition to the items and Random periods.   bankruptcy 7 strikes you clear of the command-line consumer interfaces that seem in prior chapters and towards graphical consumer interfaces. You first find out about the summary Window Toolkit starting place, after which discover the Java origin sessions when it comes to 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, movement, and writer/reader sessions. New I/O is roofed in Appendix C. bankruptcy nine introduces you to Java's community APIs, equivalent to sockets. It additionally introduces you to the JDBC API for interacting with databases. bankruptcy 10 dives into Java's XML aid via first proposing an creation 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 come upon namespace contexts, extension features and serve as resolvers, and variables and variable resolvers. bankruptcy eleven introduces you to Java's aid for SOAP-based and RESTful net providers. as well as supplying you with the fundamentals of those net carrier different types, bankruptcy eleven offers a few complicated themes, reminiscent of operating with the SAAJ API to speak with a SOAP-based net provider with no need to depend upon JAX-WS. you are going to get pleasure from having realized approximately XML in bankruptcy 10 prior to diving into this bankruptcy.   bankruptcy 12 is helping you set to take advantage of many of the wisdom you've gotten collected in prior chapters by way of displaying you ways to exploit Java to put in writing an Android app's resource code. This bankruptcy introduces you to Android, discusses its structure, exhibits you the way to put in beneficial instruments, and develops an easy app. Appendix A provides the ideas to the programming workouts that seem close to the top 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 themes: Accessibility, ByteArrayOutputStream and ByteArrayInputStream, classloaders, Console, machine, Drag and Drop, Dynamic structure, Extension Mechanism and ServiceLoader, dossier Partition-Space, dossier Permissions, Formatter, photograph 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, circulate Tokenizer, StringTokenizer, SwingWorker, method Tray, Timer and TimerTask, instruments and the Compiler API, Translucent and formed Window, and XML electronic Signature. Appendix D offers a gallery of important purposes that show numerous elements of Java. regrettably, there are limits to how a lot wisdom should be filled right into a print publication. therefore, Appendixes A, B, C, and D should not incorporated during this book's pages. in its place, those appendixes are freely dispensed as PDF records. Appendixes A and B are bundled with the book's linked code dossier on the Apress web 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 technique Invocation and Corba, robotic, Runtime and strategy, Swing Timer, and lots of different APIs/architecture themes (including an entire travel of Swing components). in fact, it's going to take time to put in writing approximately those themes so do not anticipate them all to seem instantly -- they're going to slowly emerge in coming months (although smaller issues reminiscent of robotic will emerge a lot faster). What you’ll study the full Java language, together with Java 7-specific good points comparable to turn on string, try-with-resources, ultimate rethrow, multicatch, and SafeVarargs a tremendous 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 program launcher how you can create person interfaces, operating with net companies, and a complete lot extra the fundamentals of having all started with Android app development   Who this e-book is forThis e-book goals the next teams of builders: beginners, expert (to a point) in different programming languages yet without earlier publicity to Java Intermediate Java builders, expert within the basics of Java sooner than Java 7 and looking out to extend their knowing of Java 7 language/API alterations All builders having a look past regular 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 all started with Java learning sessions and items Exploring complex Language gains traveling Language and application APIs accumulating items traveling extra application APIs developing and Enriching Graphical person Interfaces Interacting with Filesystems Interacting with Networks and Databases Parsing, growing, and remodeling XML records operating with internet providers Java 7 Meets Android

Example text

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. ŠŠŠ*/ ŠŠŠif (year%400 == 0) ŠŠŠŠŠŠreturn true; ŠŠŠelse ŠŠŠif (year%100 == 0) ŠŠŠŠŠŠreturn false; ŠŠŠelse ŠŠŠif (year%4 == 0) ŠŠŠŠŠŠreturn true; ŠŠŠelse ŠŠŠŠŠŠreturn false; } This example introduces a method for determining whether or not a year is a leap year.

Figure 1-5. The binary representation of two byte integer values begins with a sign bit. The minimum and maximum values of the floating-point and double precision floating-point types refer to IEEE 754, which is a standard for representing floating-point values in memory. org/wiki/IEEE_754) to learn more about this standard. Note Developers who argue that Java should only support objects are not happy about the inclusion of primitive types in the language. However, Java was designed to include primitive types to overcome the speed and memory limitations of early 1990s-era devices, to which Java was originally targeted.

Although I won9t write the aforementioned six free chapters as described in Learn Java for Android Development (I can9t keep the entire promise anyway because I9ve integrated Chapters 12, 13, and 14 into Beginning Java 7 as Chapters 9 and 10), the other three chapters (11, 15, and 16) are merged into Appendix C, which is free. As time passes, additional chapters will appear in that appendix; and so I will finally keep my promise, but in a different way. Note I don9t discuss code conventions for writing source code in this book.
