You need to add appropriate comments for methods and variables for these programs.

The purpose of this first assignment is to review some concepts from Computer Science I. Create a project called Assignment 1. You will then write two classes: Clock.java Write a class named Clock that contains the following variables, methods, and constructors: (a) Private instance variables that store hours (0-23), minutes (0-59), and seconds (0-59). (b) A constructor that initializes the hours, minutes, and seconds to values specified by parameters. (c) A constructor that initializes the hours, minutes to values specified by parameters (defaulting the seconds to 0) (d) A constructor that initializes the hours to a value specified by a parameter (defaulting the minutes and seconds to 0) (e) A no-arg constructor that sets the hours, minutes, and seconds to 0. (f) A method that resets the hours, minutes, and seconds to 0. (g) A method that advances the clock by one second. (h) Getters and setters for hours, minutes, and seconds. (i) A toString method that returns the hours, minutes, and seconds as a string of the form hh:mm:ss. TestClock.java - A driver class that contains only a main method that testing all constructors and methods in the class
