Multithreading refers to two or more tasks executing concurrently within a single program. A thread is an independent path of execution within a program. Many threads can run concurrently within a program. Every thread in Java is created and controlled by the java.lang.Thread class . A Java program can have many threads, and these threads can run concurrently, either asynchronously or synchronously. Multithreading has several advantages over Multiprocessing such as;

Design Patterns

In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

Java API Design Guidelines

Dr. Dichotomy's Development Diary Java API Design Guidelines by Eamonn McManus December 28, 2005 Summary There are tons of books and articles about how to design and write good Java code, but surprisingly little about the specific topic of API design. Here's a summary of what I've learnt on the subject from various sources and my own experience.

Abstract Factory Design Pattern

Intent 01 Provide an interface for creating families of related or dependent objects without specifying their concrete classes. A hierarchy that encapsulates: many possible “platforms”, and the construction of a suite of “products”. The new operator considered harmful.

How to use ArrayList in Java

The ArrayList class extends AbstractList and implements the List interface. ArrayList supports dynamic arrays that can grow as needed. In Java, standard arrays are of a fixed length. After arrays are created, they cannot grow or shrink, which means that you must know in advance how many elements an array will hold. But, sometimes, you may not know until run time precisely how large of an array you need.

coding, by Derek Young: Using Eclipse Efficiently

Using Eclipse Efficiently Wednesday November 14, 2007 by Derek Young Eclipse is a powerful tool with a lot of features. I’m always looking for tips on working more efficiently. Most of the time when I come across a page of Eclipse tips it’s just the most basic usage, like “hit F3 to go to a declaration!” I’ve tried to put together some lesser known tips and features that I see my coworkers overlooking when I stop by their cube.

The myth of the Muslim vote bank, though denied by sociologists and debunked by psephologists, refuses to die. It reasserts itself with new vigour at every election. Even those well aware of the diversity within the community cannot resist building their arguments on this spurious claim.

Use DOM parser to deal with XML document with attributes : DOM Node « XML

XML Parsers

In order to avoid the difficulties inherent in parsing raw XML input, almost all programs that need to process XML documents rely on an XML parser to actually read the document. The parser is a software library (in Java it’s a class) that reads the XML document and checks it for well-formedness. Client applications use method calls defined in the parser API to receive or request information the parser retrieves from the XML document.

A RESTful Web service, an example

It's often hard for people to "get" REST, this is mostly due to the fact that REST isn't a tangible thing like a piece of software or even a specification, it's a selection of ideals, of best practices distilled from the HTTP specs. I've always found that the best way to understand something is to see an example, to see the principles in action first and worry about the details later once I understand the general gist. So here's a little example of a RESTful version of a simple Web service you might already know about, the Delicious API . Delicious has a simple REST API , or rather, a simple POX over HTTP API, that is, it has a perfectly usable HTTP and XML based API for accessing your bookmarks and tags, but it isn't very RESTful.
