Real - Java floating point library for MIDP devices-Current version: 1.13 Copyright: 2003-2009 Roar Lauritzsen, roarl at users.sourceforge.net Availability: The library is available under the GPL license, or for a fee for commercial use. Develop: See http://sourceforge.net/projects/real-java Feedback: Comments, reports of use, bug reports, bug fixes, improvements, performance tests and comparisons to similar libraries are all welcome. Javadoc: Read the full documentation here. "Real.java" is a self-contained, single file Java floating point emulation library for MIDP devices, such as a Java-enabled cell-phone or PDA. The MIDP/CLDC 1.0 standard does not support the basic floating point types "float" or "double", so when I set out to program a scientific calculator for my cell-phone, I had to reinvent floating point arithmetic from scratch, using only integer basic types. I found it a very interesting and educating challenge. Download For a pure java version, use the f

图书馆管理系统是图书馆管理工作中不可缺少的部分，它对于图书馆的管理者和使用者都非常重要，所以图书馆管理系统应该为管理者与读者提供充足的信息和快捷的数据处理手段，但长期以来，人们使用传统的人工方式或性能较低的图书馆管理系统管理图书馆的日常事务，操作流程比较繁琐。一个成功的图书馆管理系统应提供快速的图书信息检索功能、快捷的图书借阅、归还流程。从读者与图书馆管理员的角度出发，本着以读者借书、还书快捷、方便的原则，本系统具有以下特点：  确保系统具有良好的系统性能，友好的用户界面。  较高的处理效率，便于使用和维护。  采用成熟技术开发，使系统具有较高的技术水平和较长的生命周期。  系统尽可能简化图书馆管理员的重复工作，提高工作效率。  简化数据查询、统计难度。 -Library management system is the work of library management indispensable part of its managers and users of the library are very important, so the library management system for managers and readers should provide sufficient information and efficient means of data processing, but a long time , the use of traditional artificial or lower performance of the library management system of the day-to-day management of library services, operating relatively cumbersome process. A successful library management system should provide rapid information retrieval library features, and quick to borrow books, the return pro

演示了处理鼠标事件的基本作法，为获取鼠标事件的名称和坐标值，特意定义了一个函数SetValues（），返回鼠标事件名称s，坐标值xPos,yPos。作为最直观的表示，随着鼠标的动作，在paint()立即显示鼠标事件的名称和坐标值。在这个基础上稍加改动，当拖动鼠标时，在其移动路径上连续地留下一系列的小圆点。当点击鼠标后，在其位置上画一个红色小十字。-demonstration of the mouse handle basic approach to mouse events access the names and coordinates, specifically defines a function SetValues (), to name s mouse events, coordinates xPos, yPos. As the most intuitive, as the mouse moves, the paint () immediately showed the mouse names and coordinates. On this basis is modified, when the Drag, on his mobile straight path, leaving a series of small dots. When the click of a mouse, in its place painted a small red cross.
