Each object of this class should represent a time on a standard 12-hour clock, storing the hour, min ute, and either "am" or "pm". The earliest possible time is 12:00am, and the latest possible time is 11:59pm. The constructor should have three parameters: an int for the hour, an int for the minute, and a String that is either "am" or "pm". If an of the parameters is not valid, the constructor should throw an IllegalArgumentException. The valid hours are 1-12, the valid minutes are 059, and thestring must either be "am" or "pm" to be valid. There should be standard getter methods: getHour, getMinute, getAmorPm. ClockTime should override the toString method (of the Object class) so that it returns a String consisting of the following: the hour ( one or two digits), then a colon (:), then the minute (always two digits), and then either "am" or "pm". Examples: "10:33am", "9:45pm" "12:07pm". ClockTime should also override the equals method of the Object class. Equality should be determined in the obvious way: two Cloc kTimes should be considered equal if and only if they have the same hour, have the same minute, and are either both "am" or both "pm". ClockTime should implement the Comparable interface. ClockTimes should be ordered chronologically. Examples: - 2:30am should be considered less than 1:30pm - 12:30am should be considered less than 1:30am Paste your solution in ClockTime.java, below. The other file, ClockTimeTest.java, contains code to test your solution. You may copy the testing code, but do not modify it. (This exercise is mostly taken from a Practice-It exercise.) Additional Notes: Regarding your code's standard output, CodeLab will check for case errors but will ignore whitespace (tabs, spaces, newlines) altogether
