java c/s中的日期选择控件 按钮式

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（按钮所在对话框）, JTextField tf（要生成日期的文本框）
