基于JavaSwing的电脑写字板的设计与实现
摘要：目前，很多新的技术领域都涉及到了Java语言，Java语言是面向对象编程，并且涉及到网络、多线程等重要的基础知识，因此Java语言也是学习面向对象编程和网络编程的首选语言。此简易JAVA写字板程序，使用Java程序编写，能够进行输入文字操作，并具有新建文件，打开文件，保存文件，退出，复制，粘贴，剪切，全选，撤销等多种基本功能。该程序主要用到了Java swing和事件监听等。

Design and Implementation of Java - Based Analog WordPad
    Abstract：ERP (Enterprise Resources Planning, Enterprise resource Planning) system is the Enterprise management software, based on information technology, with systematic management thinking, policy makers and staff for the Enterprise to provide decision operation means management platform. It is from MRP (material requirements planning) development of a new generation of integrated management information system, it expanded the function of MRP, its core idea is to supply chain management. It can be all of the resources of the enterprise to conduct a comprehensive management, integrated optimization of enterprise all the resources, realizing accurate production, accelerate the capital turnover, reduce inventory, reduce cost, improve labor productivity, improve customer satisfaction, enhance the core competitiveness of enterprises.
