The revised edition of the classic Core Java™, Volume II—Advanced Features, covers advanced user-interface programming and the enterprise features of the Java SE 6 platform. Like Volume I (which covers the core language and library features), this volume has been updated for Java SE 6 and new coverage is highlighted throughout. All sample programs have been carefully crafted to illustrate the latest programming techniques, displaying best-practices solutions to the types of real-world problems professional developers encounter.<br> Volume II includes new sections on the StAX API, JDBC 4, compiler API, scripting framework, splash screen and tray APIs, and many other Java SE 6 enhancements. In this book, the authors focus on the more advanced features of the Java language, including complete coverage of <br> Streams and Files <br> Networking <br> Database programming <br> XML <br> JNDI and LDAP <br> Internationalization <br> Advanced GUI components <br>

Nothing is as constant as change, and this is as true in enterprise computing as anywhere else. With the recent release of Java 2 Enterprise Edition 1.4, developers are being called on to add even greater, more complex levels of interconnectivity to their applications.<br> To do this, Java developers today need a clear understanding of how to apply the new APIs, use the latest open source Java tools, and learn the capabilities and pitfalls in Java 2 Enterprise Edition 1.4 -- so they can plan a technology and implementation strategy for new enterprise projects.

Java基础部分：基础部分的顺序：基本语法，类相关的语法，内部类的语法，继承相关的语法，异常的语法，线程的语法，集合的语法，io 的语法，虚拟机方面的语法，其他。有些题来自网上搜集整理，有些题来自传智播客学员面试后的反馈，说真的，少数一些网上的面试题，我真怀疑其是否还有存在价值！

Java Platform Enterprise Edition, v 5.0 API Specifications。 Activation Framework 所知的 JavaBean 组件实现此接口，以找出请求这些组件执行的命令动词，并获取表示这些组件要操作的数据的 DataHandler。不实现此接口的 JavaBean 也同样可以使用。这类命令可以使用 Externalizable 接口或特定于应用程序的方法来获取数据。用请求处理的动词和描述将要操作的数据的 DataHandler 来初始化 Command。注：调用者为 DataHandler 传递 null 值是可以接受的。

1还是做了一些更改，包括API的实现。关于V2.3.1版本的元数据提取可以参考我之前写的文章： Java读取图片EXIF信息 。 接下来看看如何使用Metadata-extractor类库来读取图
