When writing a library it is very useful to log information. However there are many logging implementations out there, and a library cannot impose the use of a particular one on the overall application that the library is a part of. The Logging package is an ultra-thin bridge between different logging implementations. A library that uses the commons-logging API can be used with any logging implementation at runtime. Commons-logging comes with support for a number of popular logging implementations, and writing adapters for others is a reasonably simple task. Applications (rather than libraries) may also choose to use commons-logging. While logging-implementation independence is not as important for applications as it is for libraries, using commons-logging does allow the application to change to a different logging implementation without recompiling code. Note that commons-logging does not attempt to initialise or terminate the underlying logging implementation that is used at runtime; that is the responsibility of the application. However many popular logging implementations do automatically initialise themselves; in this case an application may be able to avoid containing any code that is specific to the logging implementation used.
Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities. There are many features, including: Bag interface for collections that have a number of copies of each object BidiMap interface for maps that can be looked up from value to key as well and key to value MapIterator interface to provide simple and quick iteration over maps Transforming decorators that alter each object as it is added to the collection Composite collections that make multiple collections look like one Ordered maps and sets that retain the order elements are added in, including an LRU based map Reference map that allows keys and/or values to be garbage collected under close control Many comparator implementations Many iterator implementations Adapter classes from array and enumerations to collections Utilities to test or create typical set-theory properties of collections such as union, intersection, and closure
The Apache Commons Pool open source software library provides an object-pooling API and a number of object pool implementations. Version 2 of Apache Commons Pool contains a completely re-written pooling implementation compared to the 1.x series. In addition to performance and scalability improvements, version 2 includes robust instance tracking and pool monitoring.
