1、java课程设计万年历 1.设计分析：1.1需求分析 对于万年历系统，其主要功能是：查看当日日期（年、月、日）、查看当时时间、查看其他年月的月历、对选中的日期进行标识。主要使用流程是：查看万年历系统，查看其他月份或年份日历，选中其他日期查看，查看当日日期。1.2功能设计本程序要构建的万年历程序，其功能有以下几个方面：（1）通过JDK环境运行，实现图像界面。（2）能以月历的形式显示日期与星期。（3）支持用户自己用下拉形式来选择年份和月份。（4）通过点击“更新时间”按钮来刷新当前时间。 2.程序结构：3.各模块功能及程序说明：3.1 各种包的导入：import java.awt.BorderLay
