Java Write the class definition for a Date class that contains three integer dat

Question

Java

Write the class definition for a Date class that contains three integer data members: month, day, and year. Include a default constructor that assigns the date 1/1/2000 to any new object that does not receive arguments. Also include a function that displays the Date object. Write a main() function in which you instantiate two Date objects -- one that you create using the default constructor values, and one that you create using three arguments -- and display its values. Save the file as Date.java. You will use the Date class in other assignments later.

Explanation / Answer

Date.java

package test1;

public class Date {
   private int day;
   private int month;
   private int year;
   public Date(){
       day = 1;
       month = 1;
       year = 2000;
   }
   public Date(int day, int month, int year){
       this.day = day;
       this.month = month;
       this.year = year;
   }
   public int getDay() {
       return day;
   }
   public void setDay(int day) {
       this.day = day;
   }
   public int getMonth() {
       return month;
   }
   public void setMonth(int month) {
       this.month = month;
   }
   public int getYear() {
       return year;
   }
   public void setYear(int year) {
       this.year = year;
   }
   public void display(){
       System.out.println("Day: "+day+" Month: "+month+" Year: "+year);
   }
   public static void main(String arg[]){
       Date d1 = new Date();
       d1.display();
       Date d2 = new Date(2,3,1900);
       d2.display();
   }
}

Output:

Day: 1 Month: 1 Year: 2000
Day: 2 Month: 3 Year: 1900
