Enhance the TheTime class by adding following methods and variables to their designated section in the class 1. Two private constants that models the maximal numerical value of hour, and minutes/second 2. isValidTime() method that returns a boolean true if the time is valid and false otherwise. Use the defined constant in the method. 3. A private variable that records the number of valid TheTime objects created during the runtime, and its corresponding getter method. 4. toString() method that return the time with the format of HH:MM:SS, as well as if the time is valid. Numbers that are less then 10 should have a leading zero, eg: 09:30:02 5. Modify the constructor so that the variable defined in step 3 increments when a valid time is created, otherwise print out a message to user to reassignment valid values 6. isEqual The Time t) method that returns if the times are equal 7. nextsecond() method that returns next second of the current time. If the hour goes over 23, the next second should be 00:00:00
