Libraries for common tasks such as CSV, Base64, Circular Buffers, MD5, and Significant Figures.
JTimepiece is an advanced library for working with dates and times in Java. Features include: reduces number of objects created when working with multiple date/times, methods for computing difference between two date/times, support for time zones, leap year and daylight savings, methods for converting between string and date/times, methods for adding and subtracting to and from date/times, methods for easily retrieving individual parts of date/times, no dependencies to other non-standard Java libraries, compatible with J2SE 1.2 and above.
The POI project is the master project for developing pure Java ports of file formats based on Microsoft's OLE 2 Compound Document Format. OLE 2 Compound Document Format is used by Microsoft Office Documents, as well as by programs using MFC property sets to serialize their document objects.
There following are ports, packages or components contained in the POI project:
* POIFS is the set of APIs for reading and writing OLE 2 Compound Document Formats.
* HSSF is the set of APIs for reading and writing Microsoft Excel 97(-XP) spreadsheets.
* HWPF is the set of APIs for reading and writing Microsoft Word 97(-XP) documents.
* HSLF is the set of APIs for reading and writing Microsoft PowerPoint 97(-XP) documents.
* HPSF is the set of APIs for reading property sets.
Java applications are typically deployed in multiple environments and platforms, each requiring some unique configuration. JFig gives developers a simple yet powerful tool to manage their applications configuration. It allows them to:
* Store application configuration in one common repository of XML files
* Access configuration data using one common,
* Easily define multiple configurations, dynamically modifying those variables that need to change in different situations
* Eliminate the error prone practice of defining the same configuration variables in multiple locations
* Ease the management, deployment, and control of configuration files
JoSQL provides SQL capabilities for querying, ordering, and grouping of collections of Java objects. It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped. It should be used when a RDBMS is either too heavyweight or too impractical.
Jodd is a generic purpose open-source Java library. It helps in development of Java applications, both stand-alone and server-side. You may think of Jodd as swiss army knife for Java: small, sharp and with plenty handy gadgets included.
Jodd contains many useful and ready to use features: it provides Java beans manipulation, loads beans with ease from various sources, simplifies JDBC connectivity and code, profiles sql queries, manages date and time, manipulates and format Strings, searches files on disk, helps with handling servlet requests. Additionally, Jodd contains small, yet useful mvc2 JSP-based framework. And there is more inside...
Line is a Java library for handling console input. It is similar in functionality to BSD editline and GNU readline. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.
Retrotranslator is a Java bytecode transformer that translates Java classes compiled with JDK 5.0 into classes that can be run on JVM 1.4. Supported features: generics, annotations, reflection on generics and annotations, enums, autoboxing, for-each loop, varargs, static import, concurrency utilities, collections framework enhancements.
