COSC 1174 Chapter 10 Lab Programming Assignment
Design and implement a MyDate class. The class contains:
The data fields year, month, and day that represent a date. The variable month is 0-based, meaning that a value of 0 is for January.
A no-arg constructor that creates a MyDate object for the current date.
A constructor that constructs a MyDate object with a specified elapsed time since midnight, January 1, 1970 in milliseconds.
A constructor that constructs a MyDate object with the specified year, month, and day.
Three getter methods for the data fields year, month, and day, respectively.
A method named setDate(long elapsedTime) that sets a new date for the object using the elapsed time.
The UML diagram for this object will be discussed in class. The test client program is included below. Please develop your Java class and use the test program to ensure correct results. Upload both the test client program and your Java class to Blackboard.
import java.util.*;
public class TestMyDate {
public static void main(String[] args) {
MyDate date = new MyDate();
System.out.println("year: " + date.getYear());
System.out.println("month: " + date.getMonth());
System.out.println("day: " + date.getDay());
date = new MyDate(561555550000L);
System.out.println("year: " + date.getYear());
System.out.println("month: " + date.getMonth());
System.out.println("day: " + date.getDay());
}
}
Use the GregorianCalendar class from chapter 9 (Exercise 9.5) to simplify your coding. You may have to look this class up in the Java documentation (online). The elapsed time value specified above should produce a date of October 18, 1987. Here is what your no-arg constructor for the class might look like using the GregorianCalendar class.
MyDate() {
GregorianCalendar date = new GregorianCalendar();
// Find year, month, and day from date.
year = date.get(Calendar.YEAR);
month = date.get(Calendar.MONTH);
day = date.get(Calendar.DAY_OF_MONTH);
}
Tip: Note that the GregorianCalendar class inherits the Calendar class, so all methods of Calendar are available to GregorianCalendar.
Design and implement a class named MyInteger. The class contains:
An int data field named value that stores the int value represented by this object.
A constructor that creates a MyInteger object for the specified int value.
A getter method that returns the int value.
The methods isEven(), isOdd(), isPrime() that return the true value if the value in this object is even, odd, or prime, respectively.
The static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively.
The static methods isEven(MyInteger), isOdd(MyInteger), and isPrime(MyInteger) that return true if the specified value is even, odd, or prime, respectively.
The methods equals(int) and equals(MyInteger) that return true if the value in this object is equal to the specified value.
Draw the UML diagram for the MyInteger class and submit that in a Word document to Blackboard as well as the .java class file for your program. A sample of the client test program is included below. Please use your own values for integers. submit your client test program version to Blackboard along with your other files.
public class TestMyInteger {
public static void main(String[] args) {
MyInteger n1 = new MyInteger(5);
System.out.println("n1 is even? " + n1.isEven());
System.out.println("n1 is prime? " + n1.isPrime());
System.out.println("15 is prime? " + MyInteger.isPrime(15));
MyInteger n2 = new MyInteger(24);
System.out.println("n2 is odd? " + n2.isOdd());
System.out.println("45 is odd? " + MyInteger.isOdd(45));
System.out.println("n1 is equal to n2? " + n1.equals(n2));
System.out.println("n1 is equal to 5? " + n1.equals(5));
}
}
**Here is some information my Instructor gave us to further help us
Here is a coding snippet to maybe help (if you need it) with the MyDate class in our lab assignment. Remember, you can use the GregorianCalendar class so that you have access to some of the methods to use in this assignment.
If you recall, there were three constructors specified. The no-arg constructor was provided in the assignment. Here is the constructor that takes an elapsed time as an argument and converts that to a month, day, and year. You only have one constructor left to provide where the month, day, and year are passed as arguments.
MyDate(long elapsedTime) { GregorianCalendar date = new GregorianCalendar(); date.setTimeInMillis(elapsedTime); // Find year, month, and day from date. You write your own code to replace the out-dated get methods year = date.get(Calendar.YEAR); month = date.get(Calendar.MONTH); day = date.get(Calendar.DAY_OF_MONTH); }
