给两个时间：起始日期和终止日期,比如2008-12-25 2009-01-10,求一函数,把它的月数列出来,要可以跨年。
得出下面结果：
2008-10-25至2008-10-31
2008-11-01至2008-11-30
2008-12-01至2008-12-31
2009-01-01至2009-01-31
2009-02-01至2009-02-28
2009-03-01至2009-03-10

- Java code
private static void printYearMonth(String start, String end) throws Exception { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); Date s = sdf.parse(start); Date e = sdf.parse(end); Calendar cals = Calendar.getInstance(); cals.setTime(s); Calendar cale = Calendar.getInstance(); cale.setTime(e); StringBuffer sb = new StringBuffer(); while (cals.before(cale)) { sb.append(sdf.format(cals.getTime())); sb.append("至"); cals.set(Calendar.DATE, 1); cals.add(Calendar.MONTH, 1); if (cals.after(cale)) { cals = cale; sb.append(sdf.format(cals.getTime()) + "\n"); break; } cals.add(Calendar.DATE, -1); sb.append(sdf.format(cals.getTime()) + "\n"); cals.add(Calendar.DATE, 1); } System.out.print(sb.toString()); }
