　　⑶java中的getMonth()函数和Calendar.get(Calendar.MONTH)函数

　　⑷Dated=newDate();Calendarc=Calendar.getInstance();c.setTime(d);System.out.println(c.get(Calendar.MONTH));一月对应十二月对应

　　⑸javaswing中怎样使用绝对布局

　　⑹Swing中窗体具有默认的布局管理器，如JFrame使用是边界布局。虽然布局管理器能够简化程序的开发，但是为了获取最大的灵活性，可以使用绝对布局，即不使用任何布局管理器，是哦那个该布局的步骤如下：

　　⑺?使用Container.setLayout(null)方式取消布局管理器。

　　⑻使用ponent.setBounds()方法来设置每个控件的大小与位置。

　　⑼求java做动画代码
