得到当前时间

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String currentTime = df.format(new java.util.Date(System.currentTimeMillis()));

得到上月时间

GregorianCalendar cal = new GregorianCalendar();

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");

cal.add(GregorianCalendar.MONTH, -1);

String lastMonth = df.format(cal.getTime());

得到某月开始时间和结束时间

String strm = "2006-10";
SimpleDateFormat df1 = new SimpleDateFormat("yyyy-MM");
Date tdate = df1.parse(strm);
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(tdate);
System.out.println(strm+"-"+cal.getActualMaximum(cal.DAY_OF_MONTH));
System.out.println(strm+"-"+cal.getActualMinimum(cal.DAY_OF_MONTH));
