那个还可以用,不过就是没有时间的选择啊

Answer 4

给个可以格式化输入日期时间的可以用
JieFormattedDateBox box = new JieFormattedDateBox("yyyy年MM月dd日HH点mm分ss秒");
输入也可以用
JieFormattedDateBox box = new JieFormattedDateBox("HH:mm:ss");
来输入时间还可以这样用
JSpinner spinner = new JSpinner();
JieFormattedDateBox fdb = new JieFormattedDateBox(format);
spinner.setModel(fdb);
spinner.setEditor(fdb);BTW，一般来说时间是用来录入的而不是选择的/////////////////////////////////////////////////
