Creating Two different Classes for Time and Date in Java




Assignment 1;1. Create the java TimeType class (discussed in class & Chapter 8);with three private integer data fields named hours, minutes;and seconds, and implement the following public methods;TimeType();no argument contructor. Sets all private data to 0.;TimeType(int, int, int);contructor function. Set the private data according to the;three parameters. The first paramter represents hours, the;second minutes, and the third seconds. If any of the;parameters are invalid, set all private data to 0.;TimeType(TimeType);contructor function. Initializes the private data to the;values stored in the TimeType parameter;String toString();Returns the time stored in the object in the format;HH:MM:SS AM/PM;boolean Set(int,int,int);Sets the time in the object according to the three;parameters. The first paramter represents hours, the;second minutes, and the third seconds. If any of the;parameters are invalid, does nothing and;returns false. Otherwise, set the private;data according to the three parameters and returns true.;void Increase();Increases the time in the object by 1 SECOND;void Decrease();Decreases the time in the object by 1 SECOND;2. After you have created and compiled the TimeType class, create a;client Java application to test the TimeType class. This application;named TestTime, should do the following and display its results;using a Scanner object;- Create a TimeType object called time1 using the default;contructor.;- Create a TimeType object called time2 initialized to 23 hours;59 minutes, and 58 seconds;- Create a TimeType object called time3 initialized with the;values from the time2 object.;- Write the values of time1, time2, and time3 on separate lines.;- Attempt to set the time in time1 to 25 hours, 0 minutes, and 0;seconds. If successful, display the time in time1 otherwise;display the message "Invalid Time".;- Create a loop that will increase and write the time in time2 10;times.;- Create a loop that will decrease and write the time in time2 10;times.;As usual, include general comments, comment each variable and method, and format;your code neatly.;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Start Assignment 2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~;Assignment;Create a new DateAndTime class that inherits from your TimeType class;and adds the following three private integer instance variables: month, day;and year (and two arrays - see Notes below). Your class should implement the;following methods;1. DateAndTime() a no-argument constructor that sets the date to 01/01/1980 and;the hours, minutes and seconds to 0.;2. boolean setDate(int m, int d, int y);If the year and month are valid, and the day is valid for the;given month, set the month, day, and year according to the;parameters supplied and return true. If any of the parameters;are invalid, this method should do nothing and return false.;3. void increaseDay();increases the day by 1. Adjusts the month and year if necessary.;4. void decreaseDay();decreases the day by 1. Adjusts the month and year if necessary.;5. String toString();prints the date in the format Monthname day, year HH:MM:SS AM/PM;6. boolean isEqual(Date d);return true if the Date object calling the method has the same;values as the Date object passed as a paramater, otherwise return;false.;7. boolean leapYear(int yr);returns true if the parameter yr is a leap year, otherwise returns;false. A leap year occurs in years whose last two digits are;evenly divisible by four, except for centenary years not divisible by 400;8. void increaseSecond();increases the time by one second. Adjusts the date if necessary;9. void decreaseSecond();decreases the time by one second. Adjusts the date if necessary;Notes;Assume the original TimeType class from assignment #4 contains 3 additional methods;getSeconds(), getMinutes(), and getHours(). Each of these methods return the respective private instance variable.;These methods are necessary to implement increaseSecond() and decreaseSecond(). A complete working copy;of the TimeType class is available in the class folder/home2/classes/csi205/TimeType.class;In addition to the month, day, and year private instance variables, you should;create two one dimensional private instance variable arrays for the purpose of;printing the month names, and for validating the number of days in each month.;The first static final array of 12 String elements should hold the names of;each month and should be referenced by the toString() method to return the full;month name. The second array of 12 int elements should be referenced to;determine if the given day is valid for the current month. The days in each;month are: Jan 31, Feb 28, Mar 31, Apr 30, May 31 Jun 30, Jul 31, Aug 31;Sep 30, Oct 31, Nov 30, Dec 31. You should use the leapYear() method to;determine if Feb. contains 28 or 29 days.;You should create your own test client to test the implementation of your;DateAndTime class.;As usual, format your code neatly. You should comment each of your variables;and place comments before EACH method explaining its purpose.
