Java 时间戳转换为日期格式

public static void main(String[] args) {String time = System.currentTimeMillis();//获取当前时间精确到毫秒级的时间戳，例：1525849325942System.out.println(timeStamp2Date(time))}public static String timeStamp2Date(String time) {Long timeLong = Long.parseLong(time);SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//要转换的时间格式Date date;try {date = sdf.parse(sdf.format(timeLong));return sdf.format(date);} catch (ParseException e) {e.printStackTrace();return null;}}
