Question

***Needs to be written in Java***

**6.25 (CONVERT MILLISECONDS TO HOURS, MINUTES, AND SECONDS)
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.

Expert Solution

Step 1

This provided Java code defines a public static method called convertMillis that takes a long argument representing a duration in milliseconds and returns a String in the format of "hours:minutes:seconds".

Inside the method, it first calculates the total number of seconds by dividing the input millis by 1000 and calculates the remaining milliseconds by taking the modulo of millis by 1000. It then calculates the number of hours, minutes, and seconds from the total number of seconds, using integer division and modulo operations.

Finally, it creates a String variable result by concatenating the calculated hours, minutes, and seconds using the + operator and the string literal ":". The resulting String is then returned by the method.
