  • Package java.util.concurrent.atomic A small toolkit of classes that support lock-free thread-safe programming on single variables.
  • A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form: boolean compareAndSet(expectedValue, updateValue);
  • Atomic classes are not general purpose replacements for java.lang.Integer and related classes. They do not define methods such as hashCode and compareTo. (Because atomic variables are expected to be mutated, they are poor choices for hash table keys.)
  • ...4 more annotations...
  • The specifications of these methods enable implementations to employ efficient machine-level atomic instructions that are available on contemporary processors.
  • java.util.concurrent.atomic Class AtomicInteger java.lang.Object java.lang.Number java.util.concurrent.atomic.AtomicInteger
  • An int value that may be updated atomically. See the java.util.concurrent.atomic package specification for description of the properties of atomic variables. An AtomicInteger is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.
  • int incrementAndGet()           Atomically increments by one the current value.

    This project will mainly contain utility stuff for diverse purpose. Initially it will primarily comprise of Spring Utilities which will perform the following purposes: Load a single resource properties file from pre-configured locations with priority based override. Application context registrar to make the context available to other interested components. Use Cacheable Jersey Client Use a generic RESTful WS Client OpenSearchDescriptor JAX-RS Provider based on XOM based DOM I/O Useful utilities for Atom Syndication Feed, such as pagination over entities, retrieval of resource to certain depth, etc.

gwt dojo javascript programming library

    The project aims to integrate the Google Web Toolkit (GWT) and the Dojo framework. Indeed the Dojo framework is very rich in term of widgets and utilities (fisheye, slider, drag and drop functionality) and the main interest is to take benefits of the huge work which has been already done by the Dojo community. In other words, it means: the Dojo widgets become GWT widgets, the Dojo utilities become GWT helper.

  • Writing your own logging framework is the perfect coding crime.
  • Writing your own logging framework is the perfect coding crime
  • Even the Sun engineers fell into this trap. Prior to Java 4, we had a perfectly good logging framework in Log4J. However, instead of adopting this into the standard Java distribution, we ended up with java.util.logging. There are lots of Java logging frameworks available, even meta-logging frameworks like SLF4J and Jakarta Commons. These are supposed to abstract the logging frameworks so you can change the implementation without touching your code.
  • ...5 more annotations...
  • Logging Levels
  • In Log4J for example, we have six default levels, FATAL, ERROR, WARNING, INFO, DEBUG and TRACE.
  • Since it is tricky assigning the correct levels in our code, we should regularly do code reviews with specific emphasis on logging levels.
  • We should be able to adjust the log levels of our individual components at runtime without restarting our application.
  • Silent Operation

    Writing your own logging framework is the perfect coding crime. If you can convince your manager to put it on the project plan, you are guaranteed to have success. At the end of each day, you will go home feeling happy and satisfied. It will feel like you are doing something creative. You will get the intellectual stimulation without the risk of failure.

    The Simple Logging Facade for Java or (SLF4J) serves as a simple facade or abstraction for various logging frameworks, e.g. java.util.logging, log4j and logback, allowing the end user to plug in the desired logging framework at deployment time. Before you start using SLF4J, we highly recommend that you read the two-page SLF4J user manual. In case you wish to migrate your Java source files to SLF4J, consider our migrator tool which can migrate your project into SLF4J in minutes. In case an externally-maintained component you depend on uses a logging API other than SLF4J, such as commons logging, log4j or j.u.l, have a look at SLF4J's binary-support for legacy APIs.

    Jisql is a Java based utility to provide a command line interactive session with a SQL server. This application is conceptually modeled on the Sybase 'isql' program with, obviously, strong similarities to Microsoft SQL/Server isql and osql (as Microsoft got SQL Server from Sybase). The program can act in a similar way to Oracle's sqlplus and PostgreSQL's psql.

    A package is a group of similar types of classes, interfaces and sub-packages. Package can be categorized in two form, built-in package and user-defined package. There are many built-in packages such as java, lang, awt, javax, swing, net, io, util, sql etc. Here, we will have the detailed learning of creating and using user-defined packages.
