long型转日期型

//时分秒格式//不知为何，出来的时间有点差别

public class Test { public static void main(String[] args) throws Exception {  long time = 25978000;  System.out.println(getTime(time)); } public static String getTime(long time) {  String str = "" ;  time = time / 1000;  int s = (int) (time % 60);  int m = (int) (time / 60 % 60);  int h = (int) (time / 3600);  str = h + "小时" + m + "分" + s +"秒";    return str ; }}

//年月日时分秒long timeTemp = System.currentTimeMillis(); //25978000;long time = timeTemp; long mSec = time % 1000; time /= 1000; long year = time/(365*24*3600);time = time%(365*24*3600);long month = time/(30*24*3600); time = time % (30*24*3600);long day = time/(24*3600);time = time % (24*3600); long hour = time/3600;time = time % 3600; long min = time/60;time = time % 60; long sec = time;System.out.println(timeTemp+"毫秒是："+year+"年"+month+"月"+day+"天"+hour+"小时"+min+"分钟"+sec+"秒零"+mSec+"毫秒");

//此方法与系统时间相一致long dd = 2597800000000;Date d = new Date(dd);SimpleDateFormat f = new SimpleDateFormat("YYYY:MM:DD:HH:mm:ss");System.out.println(f.format(d));

//先把long型转换为日历日期型long aa = 25978000;Date date = new Date();date.setTime(aa * 1000);Calendar cal=Calendar.getInstance();cal.setTime(date);

再通过日期类获取时分秒，并组合成你要的字符串cal.HOUR、cal.MINUTE、cal.SECOND。
