卡通时钟的设计

1、卡通时钟的设计姓名： 学号： 专业： 班级：一、概述JAVA程序设计是计算机相关专业的必修专业基础课程，其实践性、应用性很强。实践教学环节是必不可少的一个重要环节。本课程的程序设计专题实际是计算机相关专业学生学习完JAVA程序设计课程后，进行的一次全面的综合训练，JAVA程序设计的设计目的是加深对理论教学内容的理解和掌握，使学生较系统地掌握程序设计及其在网络开发中的广泛应用，基本方法及技巧，为学生综合运用所学知识，利用软件工程为基础进行软件开发、并在实践应用方面打下一定基础。按课程设计指导书提供的课题，要求学生在自行完成各个操作环节，并能实现且达到举一反三的目的，完成一个项目解决一类问题。要求

2、学生能够全面、深入理解和熟练掌握所学内容，并能够用其分析、设计和解答类似问题；对此能够较好地理解和掌握，能够进行简单分析和判断；能编写出具有良好风格的程序；掌握JAVA程序设计的基本技能和面向对象的概念和方法；了解多线程、安全和网络等编程技术。同时培养学生进行分析问题、解决问题的能力；培养学生进行设计分析、设计方法、设计操作与测试、设计过程的观察、理解和归纳能力的提高。二、主要内容本次设计主要是要时钟有良好的界面，比较简洁美观，有很强的实用性，实现程序与电脑的时间的同步，可以显示时钟，可以显示分针秒针，并且也可以在相应位置调整时间。而且初始运行会自动与电脑的时间校对，一般默认为同步，还要可以自

3、己再次调节，提高了实用性。本系统共包括1个java源文件。1、Clock源文件是本程序的主函数其作用是初始化棋盘。2、setCurrentTime源文件实现电脑设置时间。3、源文件为时针.4、paintSecondPointer源文件实现人与电脑设置秒针.5、paintMinuteDot源文件人与电脑 三、程序代码电脑设置时间public void setCurrentTime(Date time) this.currentTime.setTime(time); public void setCurrentTime(long millis) this.currentTime.setTimeIn
