日历源程序带有需求分析及截图.doc

Java实训报告课 程 名：java课程设计适用专业：软件工程班级：软件089姓名：曹火霞指导老师：王映龙江西农业大学软件学院 2010 年8 月需求分析【需求功能描述】用一种熟悉的语言编写一个日历程序,该日历要实现的功能有一下几个:、当程序运行时,显示的时间是系统当前时间;、可以手动输入时间,确定后系统要跳转到指定的时间,并显示出星期几.、提供一种点击功能,通过点击,可以实现月份的自增,自减,日期的自增,自减功能.、要求星期日显示的位置是在星期一前面.、系统要提供一种良好的工能扩展接口,以方便以后对本系统进行功能扩展.【需求界面描述】、最要紧的是界面要足够的清爽.、界面布局要合理、日历的界面初始大小不宜过大,以300*300为宜【性能需求】、要提供一种良好的异常处理机制。、要对发生了异常的事件进行精确的判断，并进行处理。、程序的可移植性要好，尽量消除对环境的依赖。【总体设计】、数据流图初始化标签新建label标签初始化年、月、日初始化时间显示面板初始化自增、自减按钮新建label标签初始化星期显示栏初始化画布、容器添加所有组件Main()函数实例化一个对象【测试计划说明书】测试用例的设计：针对此系统我们主要采用黑盒测试和白盒测试。下面是具体的测试计划：1、 黑盒测试：从系统界面入手，采用规则和不规则，合理与不合理的数据为输入，以观察输出结果是否与预期结果或者是需求分析描述的结果相符。并且详细的记录每一种测试用例，以备后续的回归测试和分析与总结测试结果用。2、 白盒测试：从系统的逻辑结构出发，针对结构的每一个分支进行测试。其次，再辅以单元测试、集成测试、回归测试、以及最终用户的确认测试。所谓单元测试，是针对程序的每一个功能模块进行测试，等到确认该功能模块正确无误在进行该模块的集成测试。单元测试保证了每一个功能模块的正确性。所谓集成测试，是将每一个功能模块以此地、逐步地集成在一起进行测试，以观察各个功能模块之间的相容性。如果测试到某一阶段时发现错误，此时我们就必须对源程序进行相应的修改，然后进行回归测试。在所有的测试完成且无异常，错误之后。我们把系统交给用户，让用户对本系统进行确认测试。确认测试是最后一道测试工序，它将决定用户是否接收本系统。【程序实现】以下是本系统的代码实现。package com.hhj;import java.awt.BorderLayout;/引入BorderLayout类，用以对窗口进行布局import java.awt.Color;/引入awt的颜色类import java.awt.Dimension;import java.awt.GridLayout;import java.awt.SystemColor;/引入系统颜色类import java.awt.event.ActionEvent;/引入动作事件类import java.awt.event.KeyEvent;import java.awt.event.MouseEvent;import java.util.Calendar;
