Ⅱ java中的日期時間如何選擇控制項

swingx你可以到maven庫裡面搜索Jar包（google "maven repos"，出現很多maven庫，隨便找一個，搜索swingx，找最新的下載。如果你使用maven管理項目，那更好辦了，把swingx放入依賴裡面即可）。

JXDatepicker的使用方法：
// JXDatePicker提供了編輯器供用戶直接輸入日期，也提供了右側按鈕，點擊按鈕出現日期選擇期供用戶選擇日期。
JXDatePicker datePicker = new JXDatePicker();
JXDatePicker datePicker1 = new JXDatePicker(new java.util.Date());
java.util.Date date = datePicker.getDate(); // 用戶輸入或選擇日期後得到日期值
java.util.Date date1 = datePicker1.getDate(); // 用戶輸入或選擇日期後得到日期值
//當然，你也可以指定用戶輸入日期的格式。
JXDatePicker datePicker2 = new JXDatePicker();
datePicker2.setFormats("yyyy.M.d", "yyyy-M-d");//可同時設置多種格式。setFormats(String...format)

JXMonthView的使用方法：
JXMonthView monthView = new JXMonthView();
monthView.setUnselectableDates(new java.util.Date());// 設置多個不可選擇的日期，setUnselectableDates(java.util.Date ... date)
Set<java.util.Date> unselectable = monthView.getSelectionModel().getUnselectableDates();// 獲得當前有哪些不可選擇日期
monthView.setFlaggedDates(date1,date2)// 設置多個被標記了的日期
Set<java.util.Date> flaggedDates = monthView.getFlaggedDates();// 獲得被標記的日期
Calendar calendar = monthView.getCalendar();// 獲得日歷對象
還有一些可set,get的屬性羅列如下：
selectionMode
traversable
firstDayOfWeek
還有更多用法，看API吧。如果使用Maven，你可以自動下載javadoc和javasource。

Ⅲ 如何直接用java Swing寫日期下拉列表框

DateDropFrame extends JFrame
給year和month添加一個ItemListener來實時計算指定年和月中有多少天就可以了.
代碼是用Swing寫的,不過看你的圖,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做一個日歷顯示數據功能，在頁面上顯示日期數據。

MainFrame.java是顯示日歷程序，Clock.java是日歷計算程序（可以不要）。

編譯後運行MainFrame這個類即可。

swing窗口顯示萬年歷，jdk1.4以上環境編譯運行。
