Free java class library software for linux

Java GetOpt library implements option parsing and a common online help behaviour, including an XML format for topics, command, and options (which can be queried with --help --xml) and support for online browsing with --help --browse.

Whats New in This Release:

ï¿1⁄2 The getopt library can now choose the pluggable look and feel of an application with a standard option "--plaf".
ï¿1⁄2 A new file of default options (.prefs/default.options) can specify a set of common default options for all programs using the getopt library, such as the PLAF.

MAT Template Library is a C++ mathematical template class library. The library contains classes and routines for working with:

matrices
vectors

The Zeus Java Swing Components Library provides useful Swing components for easier GUI development. Zeus Java Swing Components Library uses only standard components to create widgets and standard patterns wherever possible.
It includes JConsole, a console replacement, JSplash, a splash screen implementation, TableSorter, which provides sorting for JTable using the tables headers, OutLookToolBar, makes JToolBar buttons resemble those of the Microsoft Outlook toolbar, WindowManager, which provides almost any functionality you need to manage all JInternalFrames within a JDesktop, SingleAppInstance, which provides a simple solution to the multiple application instances problem, SwingConfigurationManager, which provides data validation, and much more.
Enhancements:
- The old TableSorter was replaced, and all old related classes were deprecated.
- Functionality to dynamically resize a JTable based on its header and data was added.
- TypeSafe was upgraded with simple focus traversal using only the TAB key instead of CTRL+TAB for JTextArea, JTextPane, and JEditorPane.

Memory Structures Library (MemSL) is a complete data structures/collection classes library with memory tracing, memory debugging, entry/exit tracing, exception handling, definable memory handlers, built-in thread support, and much more.

The project supports single, double, and circular linked lists, AVL balanced and threaded binary trees, dynamic hashing tables, stacks, queues and dequeues (using arrays or linked lists), sets (Pascal implementation, with union, difference, intersection, etc.), bags, tables and dictionaries, priority heaps, priority search queue, and more.

Standard Als PHP Library (SAPL) is a fully object oriented library for Web development with PHP5.
Standard Als PHP Library offers many classes in several packages and is intended to satisfy simple and at the same time recurring needs in Web development.
About PHP:
PHP, short for "PHP: Hypertext Preprocessor", is an open-source, reflective programming language used mainly for developing server-side applications and dynamic web content, and more recently, a broader range of software applications.
PHP allows interaction with a large number of relational database management systems, such as MySQL, Oracle, IBM DB2, Microsoft SQL Server, PostgreSQL and SQLite. PHP runs on most major operating systems, including UNIX, Linux, Windows, and Mac OS X, and can interact with many major web servers. The official PHP website contains very extensive documentation.
There is a command line interface, as well as GUI libraries such as the Gimp Tool Kit (GTK+) and text mode libraries like Ncurses and Newt.
Enhancements:
- A generateClass method was added to the DataBase class.
- The DataBaseColumn class was added.
- getTables and getTableColumns methods were added to the DataBase class.
- The insertTuple method was optimized.
- The toString method was added to the Resource class.
- The fromFile method of the MailAttachment class now takes only one argument, the File.
- Content-Type is now obtained from the extension.
- Content-type methods were added to the File class.
- All W3C 16 color names were added.

POCO C++ Libraries project are the next generation C++ class libraries for network-centric applications.

POCO, the C++ Portable Components, is a collection of open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left open by it.

Their modular and efficient design and implementation makes the C++ Portable Components extremely well suited for embedded development, an area where the C++ programming language is becoming increasingly popular, due to its suitability for both low-level (device I/O, interrupt handlers, etc.) and high-level object-oriented development. Of course, POCO is also ready for enterprise-level challenges.

The POCO libraries free developers from re-inventing the wheel, and allow them to spend their time on more worthwhile areas, such as getting things done quickly and working on the features that make their application unique.
