Write a class named Clock to represent a clock that stores time in 12-hour format. Use appropriate visibility modifiers and appropriate data types. The class shall contain only the following items:

• A data field named hours to hold the hour part of the current time.
• A data field named minutes to hold the minute part of the current time.
• Two constant fields named AM and PM with the values 1 and 2, respectively. The constants should be accessible through the class, rather than requiring an object to access the values. These constants (rather than the literal values 1 and 2) should be used whenever you need to indicate that a time is AM or PM.
• A field named am_pm that indicates whether the current time stored is for AM or PM.
• A method named getTime() which returns the current time stored as a string in hh:mm format followed by a.m. or p.m. (e.g., 06:40 p.m.).
• The accessor and mutator (getter and setter) methods for all data fields. The accessor for am_pm should return the string representation ("a.m." or "p.m.") of the field's value.
• A constructor that creates a default clock, set to 6:00 a.m.

Write a test program that creates three Clock objects.

• The first should be a default Clock.
• Assign 11:57 p.m. to the second object.
• Assign 8:15 a.m. to the third object.

Display the time for each of the objects by invoking their getTime() method.

MUST BE IN JAVA!
