Chapter 6, Problem 3PP

Complete and fully test the class Time that Exercise 2 describes. Add two more constructors that are analogous to the setTime methods described in Parts c and d of Exercise 2. Also include the following methods:

• getTime24 returns a string that gives the time in 24-hour notation hhmm. For example, if the hour value is 7 and the minute value is 25, return “0725”. If the hour value is 0 and the minute value is 5, return “0305”. If the hour value is 15 and the minute value is 30, return “1530”.
• getTime12 returns a string that gives the time in 12-hour notation h:mm xx. For example, if the hour value is 7 and the minute value is 25, return “7:25 am”. If the hour value is 0 and the minute value is 5, return “12:05 am”. If the hour value is 15 and the minute value is 30, return “3:30 pm”.
