问题 I am trying to create an application where the user inputs a time and date into a JTable and then receives an alert at that time. The way in which I have planned it is that the entries are displayed in chronological order with the nearest on the top row and are then compared every 5 minutes to the user's date/time until they match. I feel that I can figure out everything in this plan except the actual scanning of only the top row and 2 columns out of 3 (Columns DATE and TIME, but not NAME).

问题 I need some help to be able to set the first day of week from Sunday to Monday (change SMTWTFS to MTWTFSS) in com.toedter.calendar.JDateChooser , I tried like this with no result, I'm using version 1.3.3 of JDateChooser: JDateChooser dateChooser = new JDateChooser(new Date()); dateChooser.getCalendar().setFirstDayOfWeek(Calendar.MONDAY); 回答1: Following the conventions of proper getter implementation, getCalendar() probably returns a copy of the calendar used.

问题 Excuses for asking the same question again. I am under the impression that if I added to the original question, I wouldn't get as many views. As I'm using an MVC pattern, my Swing GUI is in a different class with the controller creating an instance of it. Here is how I create the table in my View: tableVehiclePermitHeader = new String[] {"Name", "Expiration Date"}; tableVehiclePermitData = new Object[0][0]; // Calendar tempDate = new GregorianCalendar(2008, 1, 1); // Date tempDate1 = new Date

问题 In my project I am using com.toedter.calendar.JCalendar class. But I do not know how can I get date when date is chosen. JDateChooser and JXDatePicker met my need.

问题 I'am using JCalendar 's 1.4 JDateChooser so I ask if it is possible to change display names for months and days of weeks without having to change the source code, or, since I never looked the source code, is it complicated to change it even if it can be changed.
