2、 JAVA 的应用系统综合实例，自定义一个日历组件显示日期 和时间并进行适当的功能扩充，实践 Java 语言编程技术。 2、概要设计、概要设计 设计一个类用来构成日历系统的主窗口，然后编写一个框架类显示时间和提 示信息。在设计中应用了多种容器和控件。 3、自定义类及接口说明、自定义类及接口说明 （1）public void updateView()改变日期后完成更新界面； （2）抽象类 java.util.Calendar 获取系统日期并传递日期数据而且在人工改 变日期后得出当天是周几； （3）public static void main(String args) 主函数完成系统各算法的调用
