1、为了适应公司新战略的发展，保障停车场安保新项目的正常、顺利开展，特制定安保从业人员的业务技能及个人素质的培训计划java计算器发展报告　　课程设计论文　　设计题目：java计算器　　学生姓名：　　指导教师：　　专业名称：　　所在院系：　　秦皇岛职业技术学院信息工程系　　摘要　　在当今这个网络的时代，java语言在网络编程方面的优势使得网络编程有了更好的选择。Java语言最大的特点是具有跨平台性，使其不受平台不同的影响，得到了广泛的应用。该程序是一个图形界面的java计算器,其界面主要采用了swing包，程序实现了：　　

2、实现简单加、减、乘、除的运算。　　实现除了加、减、乘、除按钮外其他按钮功能。　　给软件添加一个编辑、查看、帮助的主菜单。　　在数据输入方面，提高程序代码的健壮性，增强其对非法输入数据的识别能力。　　科学型计算器与标准计算器之间的菜单切换。目的-通过该培训员工可对保安行业有初步了解，并感受到安保行业的发展的巨大潜力，可提升其的专业水平，并确保其在这个行业的安全感。为了适应公司新战略的发展，保障停车场安保新项目的正常、顺利开展，特制定安保从业人员的业务技能及个人素质的培训计划　　Java的早期版本以来，抽象窗口工具包为用户

3、界面组件提供了平台独立的API。在AWT中，每个组件都由一个原生的等同组件生成和控制，这个原生组件是由当前的图形窗口系统决定的。　　与此相对，Swing组件经常被描述为轻量级的，因为它们不需要操作系统本身所带窗口工具包的原生资源来生成。　　I　　秦皇岛职业技术学院信息工程系　　目录　　第1章概要设计·····························································································1　　查找资料············
