Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说Java毫秒转时分秒「终于解决」,希望能够帮助你!!!。

import java.util.Scanner;

public class test {
    public static void main ( String[] args ) {
        Scanner input = new Scanner( System.in );
        long n = input.nextLong( );
        System.out.println( convertMillis( n ) );
    }

 public String convertMillis (long duration) {
        if (duration != null) {
            long hour = duration/ 3600;
            long minute = (duration % 3600) / 60;
            long second = (duration % 3600) % 60;

            String hourStr = hour == 0 ? "00" : hour > 10 ? hour + "" : "0" + hour;
            String minuteStr = minute == 0 ? "00" : minute > 10 ? minute + "" : "0" + minute;
            String secondStr = second == 0 ? "00" : second > 10 ? second + "" : "0" + second;

            return hourStr + ":" + minuteStr + ":" + secondStr;
        }
        return null;
    }
}
