Need help in Java:

Write a program that uses methods. 1. Write a method named convertMilliseconds() that converts milliseconds to hours, minutes, and seconds using the following header: public static String convertMilliseconds (long millis) The method returns a String in the form hours:minutes:seconds. For example, convertMilliseconds (5500) returns the string 0:0:5, while convertMilliseconds (100000) returns the string 0:1:40, and convertMilliseconds (555550000) returns the string 154:19:10.
