关于一道时间的问题
题目是调用System.currentTimeMillis()返回从1970年到一月一号0点开始的毫秒数，要显示几几年 几月几日，几点几分几秒 ，我可以编写几点几分几秒 ，但年数 我感觉有点转不过来了 ，就大神指导一下
回复 2楼 日知己所无
你能帮我看看这个public class Testsum {
public static void main(String[] args){
long totalMilliseconds = System.currentTimeMillis();
long totalSeconds = totalMilliseconds/1000;
long currentSeconds = totalSeconds % 60;
long totalMinutes = totalSeconds / 60;
long currentMinutes = totalMinutes % 60;
long totalHours = totalMinutes / 60;
long currentHours = totalHours % 24;
long totalDay = totalHours / 24;
long totalYears = totalDay/365;
int currentYears = (int)(totalYears +1970);
int days = (int)(totalDay%365);
if((currentYears%4==0 && currentYears%100!=0 )|| currentYears%400==0){
if(days<=30){
int days2=days+1;
System.out.println("Current date and time is Junuary"+days2+", "+currentYears+" "+currentHours+":"+currentMinutes+":"+currentSeconds);
