JAVA将十位时间戳格式化为日期Date类型

一、十位数字格式时间戳格式化为日期Date类型

public static String timeStamp2Date(String seconds,String format) {          if(seconds == null || seconds.isEmpty() || seconds.equals("null")){              return "";          }          if(format == null || format.isEmpty()) format = "yyyy-MM-dd HH:mm:ss";          SimpleDateFormat sdf = new SimpleDateFormat(format);          return sdf.format(new Date(Long.valueOf(seconds+"000")));      } 

二、将秒转化成时分秒格式

public static String getTimeStr(Integer time) {Integer hour = time/(60*60);Integer minute = (time-hour*3600)/60;Integer seconds = time-hour*3600-minute*60;StringBuffer sb = new StringBuffer();if(hour.toString().length() == 1) {sb.append("0"+hour);} else {sb.append(hour);}sb.append(":");if(minute.toString().length() == 1) {sb.append("0" + minute);} else {sb.append(minute);}sb.append(":");if(seconds.toString().length() == 1) {sb.append("0" + seconds);} else {sb.append(seconds);}return sb.toString();}
