今天做java c/s程序的时候要用到一个日期选择的控件，NetBeans里面没有，所以自己写了。因为让单独的表格单元被选择不知道用哪个方法，，，所以，有知道的希望可以帮忙完善下
import java.util.Calendar;
public class CalendarBean {
int year = 2014, month = 5, nextDay;
public void setYear(int year) {
this.year = year;
}
public int getYear() {
return year;
}
public void setMonth(int month) {
this.month = month;
}
public int getMonth() {
return month;
}
public String[][] getCalendar() {
String a[][] = new String[6][7];
Calendar rili = Calendar.getInstance();
rili.set(year, month - 1, 1);
int weekday = rili.get(Calendar.DAY_OF_WEEK) - 1;
int day = 0;
if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12) {
day = 31;
}
if (month == 4 || month == 6 || month == 9 || month == 11) {
day = 30;
}
if (month == 2) {
if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) {
day = 29;
} else {
day = 28;
}
}
nextDay = 1;
for (int k = 0; k < 6; k++) {
if (k == 0) {
for (int j = weekday; j < 7; j++) {
a[k][j] = "" + nextDay;
nextDay++;
}
} else {
for (int j = 0; j < 7 && nextDay <= day; j++) {
a[k][j] = "" + nextDay;
nextDay++;
}
}
}
return a;
}
}
上面是一个日历形成的class

上面是在窗口上写一个按钮，通过按钮实现将指定文本框的值设为“YYYY-MM-DD”日期格式。其中传入的参数分别是JFrame f（按钮所在窗口）, JTextField tf（要生成日期的文本框）

这个是在对话框中的按钮上使用的，，，功能与上面个一样，通过点击按钮，将指定文本框的值设为“YYYY-MM-DD”格式的时间，其中传入的参数分别是JDialog f（按钮所在
