本文給大家分享的是使用使用java的Calendar對(duì)象獲得當(dāng)前日期的上幾個(gè)度開始、結(jié)束時(shí)間,主要思路是先獲得當(dāng)前季度的開始和結(jié)束日期,在當(dāng)前日期的基礎(chǔ)上往前推3個(gè)月即上個(gè)季度的開始和結(jié)束日期,十分的實(shí)用,小伙伴們可以參考下。 思路: 先獲得當(dāng)前季度的開始和結(jié)束日期,在當(dāng)前日期的基礎(chǔ)上往前推3個(gè)月即上個(gè)季度的開始和結(jié)束日期 /** * @param flag true:開始日期;false:結(jié)束日期 * @return */ public static String getLastQuarterTime(boolean flag){ SimpleDateFormat shortSdf = new SimpleDateFormat('yyyy-MM-dd'); SimpleDateFormat longSdf = new SimpleDateFormat('yyyy-MM-dd HH:mm:ss'); String resultDate=''; Date now = null; try { Calendar calendar = Calendar.getInstance(); int currentMonth = calendar.get(Calendar.MONTH) + 1; //true:開始日期;false:結(jié)束日期 if(flag){ if (currentMonth >= 1 && currentMonth <= 3) calendar.set(Calendar.MONTH, 0); else if (currentMonth >= 4 && currentMonth <= 6) calendar.set(Calendar.MONTH, 3); else if (currentMonth >= 7 && currentMonth <= 9) calendar.set(Calendar.MONTH, 6); else if (currentMonth >= 10 && currentMonth <= 12) calendar.set(Calendar.MONTH, 9); calendar.set(Calendar.DATE, 1); now = longSdf.parse(shortSdf.format(calendar.getTime()) + ' 00:00:00'); }else{ if (currentMonth >= 1 && currentMonth <= 3) { calendar.set(Calendar.MONTH, 2); calendar.set(Calendar.DATE, 31); } else if (currentMonth >= 4 && currentMonth <= 6) { calendar.set(Calendar.MONTH, 5); calendar.set(Calendar.DATE, 30); } else if (currentMonth >= 7 && currentMonth <= 9) { calendar.set(Calendar.MONTH, 8); calendar.set(Calendar.DATE, 30); } else if (currentMonth >= 10 && currentMonth <= 12) { calendar.set(Calendar.MONTH, 11); calendar.set(Calendar.DATE, 31); } now = longSdf.parse(shortSdf.format(calendar.getTime()) + ' 23:59:59'); } calendar.setTime(now);// 設(shè)置日期 calendar.add(Calendar.MONTH, -3); resultDate = longSdf.format(calendar.getTime()); } catch (Exception e) { ; } return resultDate; } 文章來源:http://www./article.php?CID=26&ID=677 了解更多內(nèi)容可登錄中軟國際官方網(wǎng)站:www. |
