lambdaj is a library that makes easier to address this issue by allowing to manipulate collections in a pseudo-functional and statically typed way. In our experience to iterate over collection, especially in nested loops, is often error prone and makes the code less readable. The purpose of this library is to alleviate these problems employing some functional programming techniques but without losing the static typing of java. We impose this last constraint to make refactoring easier and safer and allow the compiler to do its job.

SmartSprites will let you easily introduce and maintain CSS sprites in your designs. SmartSprites parses special directives you can insert into your original CSS to mark individual images to be turned into sprites. It then builds sprite images from the collected images and automatically inserts the required CSS properties into your style sheet, so that the sprites are used instead of the individual images. SmartSprites parses special directives you can insert into your original CSS to mark individual images to be turned into sprites. It then builds sprite images from the collected images and automatically inserts the required CSS properties to your style sheet, so that the sprites are used instead of the individual images. In other words, no tedious copying & pasting to your CSS when adding, removing or changing sprited images. Just work with your CSS and original images as usual and have SmartSprites automatically transform them to the sprite-powered version when necessary.

Many interactive Web applications are composed of brittle collections of interdependent Web pages. Such applications can be hard to maintain and extend. The Front Controller pattern defines a single component that is responsible for processing application requests. A front controller centralizes functions such as view selection, security, and templating, and applies them consistently across all pages or views. Consequently, when the behavior of these functions need to change, only a small part of the application needs to be changed: the controller and its helper classes.

I just had a java interview and they asked me about difference between ConcurrentHashMap and Collections.Synchronized-map and then again difference between ConcurrentHashMap and Hashtable. I didn't know so I searched the net found this java hashmap tutorial, this site has some really good java hashmap tutorial e..g how hashmap works in java, how concurrentHashmap is different than hashtable etc.

"The WAR Plugin is responsible for collecting all artifact dependencies, classes and resources of the web application and packaging them into a web application archive."

Hibernate Tutorial. In this hibernate tutorial, we will learn basics of hibernate, inheritance mapping, collection mapping, component mapping, HQL, HCQL, Named Query, Caching and Integration of Hibernate with other frameworks.

"Seam 3 is collection of modules and developer tools based on the Java EE platform. The modules are portable extensions to CDI that integrate with other technologies to extend the core Java EE functionality. These modules bring you many of the beloved features and integrations from Seam 2 (security, internationalization, JSF, rules, business process management) and also branch out into new areas. IDE support is provided by the JBoss Tools Eclipse plugins. Before diving in, get up to speed with the status and direction of Seam 3. Also be sure to check out the latest news at the bottom of the page. "

Reflections scans your classpath, indexes the metadata, allows you to query it on runtime and may save and collect that information for many modules within your project.

contains a strictly compatible superset of the old Google Collections Library:

"dom4j is an easy to use, open source library for working with XML, XPath and XSLT on the Java platform using the Java Collections Framework and with full support for DOM, SAX and JAXP. "

"http://www.atompub.org/ defines a simple interface over HTTP to publish and subscribe to artifacts (files) and collections of artifacts (services/packages). AtomPub interface serves following purposes: 1: provide "feeds" for people/systems to monitor for changes: For example, user subscribes to a feed which lists contents of package or user subscribes to feed which lists changed contents in a package 2. provide the default remote api to push/pull content and meta data from the repository. This allows other applications to integrate with Guvnor by accessing repository content via atom pub programmatically."

"OpenCMIS is a collection of Java libraries, frameworks and tools around the CMIS (Content Management Interoperability Services) specification. The goal of OpenCMIS is to make CMIS simple for Java client and server developers. It hides the binding details and provides APIs and SPIs on different abstraction levels. It also includes test tools for content repository developers and client application developers."

Jettison is a collection of Java APIs (like STaX and DOM) which read and write JSON. This allows nearly transparent enablement of JSON based web services in services frameworks like CXF or XML serialization frameworks like XStream. There are currently two included conventions for mapping JSON to XML. The first, is BadgerFish which implements the full XML infoset in JSON using various techniques. The second, is called the "mapped" convention. It allows you to manually map XML namespaces to JSON element prefixes. Jettison was developed for usage in XFire and CXF to enable JSON based services. Later it also found its place in Java object serialization with XStream To learn more, see the User's Guide.

JSON-lib is a java library for transforming beans, maps, collections, java arrays and XML to JSON and back again to beans and DynaBeans. It is based on the work by Douglas Crockford in http://www.json.org/java. The following tables sumarizes the types conversion between java and javascript:

Core Java Topics - Overview Of Programming With Java, Datatypes, Variables, Operators, Control Statements, Methods - Importance, Array - Overview, Classes, Class Inheritance, Methods Overiding and Overloading, Abstract Class And Methods, Interfaces, Packages and Access Control, final, static and others, Object Oriented Concepts - Revisited, Exceptions, Generics, Strings, Exploring java.lang, Collections Framework, More Utility Classes, Input/Output: Exploring java.io, Other Core Java Topics

Good collection of tutorials for java related technologies like java , java8 , spring , sping boot , hibernate , reactjs and angularjs

A good quick way of converting arraylist to set in java . ough its worth noting that all those method will eat duplicates silently and size of converted set might be less than or equal to original list.

Normally, array is a collection of similar type of elements that have contigious memory location. In java, array is an object the contains elements of similar data type. It is a data structure where we store similar elements. We can store only fixed elements in an array.
