Answer 2

声明一个接口,弄一个setDateString()方法,传到这里来,点击的时候,就给这个对象传楼上的System.out.println()中的String.需要使用这个日期的就实现这个接口.

Answer 3

你在里面加入一行代码    public static class CalendarTable extends JTable { 
     private Main frame;
        private Calendar calendar; 
        public CalendarTable(TableModel model, Calendar calendar,Main frame) { 
            super(model); 
            this.calendar = calendar; 
            this.frame = frame;
        } 
        public void changeSelection(int row, int column, boolean toggle, boolean extend) { 
            super.changeSelection(row, column, toggle, extend); 
            if (row == 0) { 
                return; 
            } 
            Object obj = getValueAt(row, column); 
            if (obj != null) { 
                calendar.set(Calendar.DAY_OF_MONTH, ((Integer)obj).intValue()); 
            } 
            //==========加入以下代码===================
            JOptionPane.showMessageDialog(frame.cPane, frame.yearsSpinner.getValue()+"-" +frame.monthsComboBox.getSelectedItem()+"-"+frame.daysTable.getValueAt(frame.daysTable.getSelectedRow(),frame.daysTable.getSelectedColumn()));        } 
    }
