Part 1 Create a UML class diagram for the Time class as described below: The class will have two integer instance variables representing hours and minutes. These will be stored in standard 24-hour time. The class must have the following methods: a default constructor that sets the time to midnight • a constructor that takes two integer variables representing the hours in 24- hour time (0-23) and the minutes in the range 0-59. This constructor will validate the constructor inputs and will set the time to midnight if either value is outside of the needed range. • a constructor that takes two integers and a string. The string must be either "AM" or "PM", and the integer will be the hours in the range 1-12 and the minutes in the range 0-60. Again, the constructor will validate the constructor inputs and will set the time to midnight if either value is outside of the needed range or the String is not "AM", "am", "PM", or "pm". • getters and setters for the hours and minutes. The setters must validate the input values and will not change the time unless the value is in valid 24 hour time range. • an equals method .toString-returns a String with the time in the form hh:mm, where hh can range from 00 to 23. • get 12 HourTime - returns a String with the time in the form hh:mm AM or hh:mm PM Create test data for 2 different Time objects (in addition to the samples below) and the results of calling methods with various inputs. Have at least 2 different method calls each for the setters, equals, toString, and get 12HourTime methods, trying to test different situations. You may use the sample objects below in your own tests. Sample test data: Code: Time timel new Time (2,30); Expected result: timel object created with hours: 2 and minutes: 30 Code: Time time2= new Time (2,45, "PM"); Expected result: timel object created with hours: 14 and minutes: 45 Code: Time time3= new Time (14,45); Expected result: timel object created with hours: 14 and minutes: 45 Code: Time time4 = new Time (25,50); 1 Espected result: time4 object created with hours: 0 and minutes: 0 (midnight - because of invalid. input) Code: time3.setMinutes (68); Expected result: time3 object not changed because of invalid input. Code: System.out.println(time3.equals(time2)); Expected result: true printed to console Code: System.out.println(time3); // calls time3.toString() automatically Expected result: 14:45 printed to console Code: Expected result: 2:45 PM printed to console 2 System.out.println(time3.get12Hour Time());
