Java enum - enum constructor, method, inheritance - HowToDoInJava
The steps involved are Create a Sax parser and parse the xml In the event handler create the employee object Print out the data Basically the class extends DefaultHandler to listen for call back events. And we register this handler with the Sax parser to notify us of call back events.
We are only interested in start event, end event and character event. In end event if the node is employee then we know we are at the end of the employee node and we add the Employee object to the list.
In character event we store the data in a temp string variable. But generating a XML file from scratch is a different story, for instance you might like to generate a xml file for the data extracted from a database.

The output will be book. In JDK 1. OutputFormat com. XMLSerializer org. OutputFormat We are using Xerces 2. Also please remember it is not advisable to use parser implementation specific classes like OutputFormat and XMLSerializer as they are only available in Xerces and if you switch to another parser in the future you may have to rewrite.
See below for steps to make your code JAXP compliant.
Getting started with new I/O (NIO)
Xerces parser is bundled with the JDK 1. So you need not download the parser separately. Crimson parser is bundled by default with JDK 1. To override this parser we need to run our example with -Djava. The JDK 1. With the significant changes made to the new release of Java Development Kit JDK , this book will act as tutorial for programmers who need to make use of he new features now. Each new or updated package or feature is given a theoretical introduction, including a discussion of the role of the package or feature within the larger Java platform.
Every technique described is With the significant changes made to the new release of Java Development Kit JDK , this book will act as tutorial for programmers who need to make use of he new features now. Every technique described is accompanied by a sample program that provides a complete implementation and can be used as a starting point for creating new code. For packages that have been overhauled, a discussion of the relevant changes is provided in the context of what the Java programmer already knows about older versions of the package and special attention is given to anything that breaks backward compatibility.

Run Eclipse by launching eclipse. Eclipse uses a built-in Java compiler.
If you find this topic of interest, you may find the following course to be useful:
The compiler supports Java 1. The level actually followed by the compiler depends on the project settings. You can configure the Java level per project or set it as a default at a global level. Launch Eclipse. Enter Test as the project name. Note that system using the default compiler compliance level of JDK 1.
We are now ready to develop code in JDK 1.
In the new project, create a package called com. In that package, create a class called Test. The code should execute fine.
