用Java编写具有图形用户界面（GUI）的日历组件显示日期和时间并进行适当的功能扩充。 主要功能： 1、显示当月日历，当前日期、当前时间； 2、可查询任意月以及任意年的日历； 3、正常运行和退出程序。 4、每日具有记账功能，需要至少包含1）记账id；2）记账类型；2）支出费用；3）关键字（关键字写为一行，关键字数量不限，使用分号分割<需查阅使用>） 5、能够通过关键字查询某一种类型的记账记录。 6、对当月记账类型的汇总；对特定关键字的记账汇总。

好的，以下是一个简单的Java代码示例，可以实现你所描述的基本功能：

这个例子中，我们使用Java的Swing库来创建GUI界面，使用Calendar类和SimpleDateFormat类来处理日期和时间，使用HashMap来存储记账记录。具体实现过程中，我们创建了一个JFrame窗口，并在窗口中添加了一个日历面板、一个查询面板和一个记账面板。我们通过监听按钮事件来实现日历的翻页、查询功能以及记账记录的添加，并在界面中实时显示当月记账汇总。
