$($Convert milliseconds to hours, minutes, and seconds$)$

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

public static String convertMillis$($long millis$)$

The function returns a string as hours:minutes:seconds. For example, convertMillis$(5500)$ returns the string $0$:$0$:$5,$ convertMillis$(100000)$ returns the string $0$:$1$:$40,$ and convertMillis$(555550000)$ returns the string $154$:$19$:$10.$

Write a test program that prompts the user to enter a value for milliseconds and displays a string in the format of hours:minutes:seconds.

Sample Run

Enter time in milliseconds: $555550000154$:$19$:$10$
