Question

public class Date

{

   private int month;

   private int day;

   private int year;

   public Date( int monthValue, int dayValue, int yearValue )

   {

      month = monthValue;

      day = dayValue;

      year = yearValue;

   }

   public void setMonth( int monthValue )

   {

      month = monthValue;

   }

   public int getMonth()

   {

      return month;

   }

   public void setDay( int dayValue )

   {

      day = dayValue;

   }

   public int getDay()

   {

      return day;

   }

   public void setYear( int yearValue )

   {

      year = yearValue;

   }

   public int getYear()

   {

      return year;

   }

    public void displayDate()

   {

      System.out.printf( "%d/%d/%d", getMonth(), getDay(), getYear() ); } }

Problem: Given the above Date class, write a Test Program to test the class. The program should initialize data fields of two objects, first using Constructor and second using Set methods. Using DisplayDate() Method, print object fields.

Answer 1

public class Date {
    private int month;
    private int day;
    private int year;

    public Date(int monthValue, int dayValue, int yearValue) {
        month = monthValue;
        day = dayValue;
        year = yearValue;
    }

    public void setMonth(int monthValue) {
        month = monthValue;
    }

    public int getMonth() {
        return month;
    }

    public void setDay(int dayValue) {
        day = dayValue;
    }

    public int getDay() {
        return day;
    }

    public void setYear(int yearValue) {
        year = yearValue;
    }

    public int getYear() {
        return year;
    }

    public void displayDate() {
        System.out.printf("%d/%d/%d", getMonth(), getDay(), getYear());
    }
}

class DateTest {

    public static void main(String[] args) {
        Date date1 = new Date(10, 14, 2020);
        Date date2 = new Date(0, 0, 0);
        date2.setDay(30);
        date2.setMonth(7);
        date2.setYear(2020);

        date1.displayDate();
        System.out.println();
        date2.displayDate();
        System.out.println();
    }
}
