Question

I need a Flowchart and Code for the following Java Program

Write a method that converts milliseconds to hours, minutes, and seconds using the following header:

public static String convertMillis(long millis)

The method returns a string as hours:minutes:seconds. For example,convertMillis(5500) returns a string 0:0:5, convertMillis(100000) returns a string 0:1:40, and convertMillis(555550000) returns a string 154:19:10. Write a test program that prompts the user to enter a long integer for milliseconds and displays a string in the format of hours:minutes:seconds.

Answer 1

import java.util.Scanner;

public class Main {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);

      
       System.out.print("Input the milliseconds: ");
       long millis = sc.nextLong();

       System.out.println("hours:minuties:seconds: " + convertMillis(millis));
   }

  
   public static String convertMillis(long millis) {
  
       millis =millis/ 1000;

       String currMinAndSec = "";
       for (int i = 0; i < 2; i++) {
           currMinAndSec= ":" + millis % 60 + currMinAndSec;
           millis /= 60;
       }
       return millis + currMinAndSec;
   }
}
