Ⅱ java中的日期时间如何选择控件
swingx你可以到maven库里面搜索Jar包（google "maven repos"，出现很多maven库，随便找一个，搜索swingx，找最新的下载。如果你使用maven管理项目，那更好办了，把swingx放入依赖里面即可）。
JXDatepicker的使用方法：
// JXDatePicker提供了编辑器供用户直接输入日期，也提供了右侧按钮，点击按钮出现日期选择期供用户选择日期。
JXDatePicker datePicker = new JXDatePicker();
JXDatePicker datePicker1 = new JXDatePicker(new java.util.Date());
java.util.Date date = datePicker.getDate(); // 用户输入或选择日期后得到日期值
java.util.Date date1 = datePicker1.getDate(); // 用户输入或选择日期后得到日期值
//当然，你也可以指定用户输入日期的格式。
JXDatePicker datePicker2 = new JXDatePicker();
datePicker2.setFormats("yyyy.M.d", "yyyy-M-d");//可同时设置多种格式。setFormats(String...format)
JXMonthView的使用方法：
JXMonthView monthView = new JXMonthView();
monthView.setUnselectableDates(new java.util.Date());// 设置多个不可选择的日期，setUnselectableDates(java.util.Date ... date)
Set<java.util.Date> unselectable = monthView.getSelectionModel().getUnselectableDates();// 获得当前有哪些不可选择日期
monthView.setFlaggedDates(date1,date2)// 设置多个被标记了的日期
Set<java.util.Date> flaggedDates = monthView.getFlaggedDates();// 获得被标记的日期
Calendar calendar = monthView.getCalendar();// 获得日历对象
还有一些可set,get的属性罗列如下：
selectionMode
traversable
firstDayOfWeek
还有更多用法，看API吧。如果使用Maven，你可以自动下载javadoc和javasource。
Ⅲ 如何直接用java Swing写日期下拉列表框
DateDropFrame extends JFrame
给year和month添加一个ItemListener来实时计算指定年和月中有多少天就可以了.
代码是用Swing写的,不过看你的图,不像是Swing界面.
/**
* Create the frame.
*/
public DateDropFrame() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new FlowLayout(FlowLayout.LEFT));
final JComboBox year = new JComboBox();
year.setModel(new DefaultComboBoxModel(getModel(start, end)));
contentPane.add(year);
final JComboBox month = new JComboBox();
month.setModel(new DefaultComboBoxModel(getModel(1, 12)));
contentPane.add(month);
final JComboBox day = new JComboBox();
contentPane.add(day);
year.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
setDay(year, month, day);
}
});
month.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
setDay(year, month, day);
}
});
setDay(year, month, day);
setContentPane(contentPane);
}
/**
* calculate days in select month & year
*/
private void setDay(JComboBox year, JComboBox month, JComboBox day) {
int y = Integer.parseInt((String) year.getSelectedItem());
int m = Integer.parseInt((String) month.getSelectedItem());
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, y);
c.set(Calendar.MONTH, m - 1);
int days = c.getActualMaximum(Calendar.DAY_OF_MONTH);
day.setModel(new DefaultComboBoxModel(getModel(1, days)));
}
/**
* get String array [start, end]
*/
private String[] getModel(int start, int end) {
String[] m = new String[end - start + 1];
for (int i = 0; i < m.length; i++) {
m[i] = String.valueOf(i + start);
}
return m;
}
Ⅳ 用java做一个日历显示数据功能，在页面上显示日期数据。
MainFrame.java是显示日历程序，Clock.java是日历计算程序（可以不要）。
编译后运行MainFrame这个类即可。
swing窗口显示万年历，jdk1.4以上环境编译运行。
