java中怎样把毫秒转成时间类型

Answer 1

java中可以使用calendar类，如下代码：
毫秒转换为日期
public static void main(String[] args) {
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
long now = System.currentTimeMillis();
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(now);
System.out.println(now + " = " + formatter.format(calendar.getTime()));
