HTML 5


What is DOM

When your browser renders a web page, it constructs a Document Object Model (DOM), a collection of objects that represent the HTML elements on the page. Every element — every , every
, every — is represented in the DOM by a different object. (There are also global objects, like window and document, that aren’t tied to specific elements.)


HTML5 defines over a dozen new input types that you can use in your forms.


< input type="search" > for search boxes : 
< input type="number" > for spinboxes
< input type="range" > for sliders
< input type="color" > for color pickers
< input type="tel" > for telephone numbers
< input type="url" > for web addresses
< input type="email "> for email addresses
< input type="date" > for calendar date pickers
< input type="month" > for months
< input type="week" > for weeks
< input type="time" > for timestamps
< input type="datetime" > for precise, absolute date+time stamps
< input type="datetime-local" > for local dates and times

Some Methods syntax needs to be remembered: protected Object readResolve() { return getInstance(); } protected void finalize() throws Throwable { try { close(); // close open files } finally { super.finalize (); // This is mandatory to write } } //normally it should be overridden to clean-up non-Java resources ie closing a file //in singleton classs public Object clone() throws CloneNotSupportedException { throw new CloneNotSupportedException(); } } –pleae note that this method is present in Object class not in Cloneable Interface as it is marker interface MultiThreading means: thread-safe = true. Overloading is providing multiple methods with the same name but different arguments (and potentially return type). Overriding is changing the behavior of a method in a subclass. Only objects are instantiated in the Java Runtime Environment (JRE) and held in a division of the program's memory allocation called the heap. S...

XML Bean

XMLBeans is an XML parser developed by BEA for WebLogic 8.1 and recently released as an open source initiative. With XMLBeans, you can access and manipulate the data contained in an XML document using Java classes. XMLBeans is different from the typical XML parser because it is designed to build applications based on known, specific schemas. At its core is a schema compiler that parses an XSD file and creates a JAR. The JAR contains a bunch of Java classes that developers can use to manipulate instance documents as if they were normal Java types. XMLBeans gives you an object-based view of the underlying XML data, without losing access to the original XML structure. In addition, it gives you an XQuery parser and XMLCursor objects that allow you to query your documents with the flexibility of a SQL database. EXAMPLE : CASE Study STEP 1: - -Open a DOS command prompt and run the 'scomp' command. If it runs without error, then congratulations, you have successfully set up XMLBea...
