Create a class called Date that includes three pieces of information as instance variables—a month (type int), a day (type int), and a year (type int). Your class should have a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day, and year separated by forward slashes (/). Write a test application named DateTest that demonstrates class Date’s capabilities

Answer:

public class Date {

   private int month;

   private int day;

   private int year;

   // Constructor

   public Date(int month, int day, int year) {

       this.month = month;

       this.day = day;

       this.year = year;

   }

   //Getters and setter

   public int getMonth() {

       return month;

   }

   public void setMonth(int month) {

       this.month = month;

   }

   public int getDay() {

       return day;

   }

   public void setDay(int day) {

       this.day = day;

   }

   public int getYear() {

       return year;

   }

   public void setYear(int year) {

       this.year = year;

   }

   void displayDate(){

       System.out.println(getMonth()+"/"+getDay()+"/"+getYear());

   }

}

//Test Class

class DateTest {

   public static void main(String[] args) {

       Date dateOne = new Date(12, 25, 2019);

       dateOne.displayDate();

   }

}

Explanation:

  • Using Java programming Language
  • Create the Date class with the instance variables (Month, day and year) all of type int
  • Create the the constructor to initialize all the instance variables
  • Create getters and setters for all the instance variables
  • Create the displayDate() method which uses string concatenation along with the get() method of all the instance variables
  • Create a test class that initializes an instance of the of the Date class
  • Call the method displayDate on the instance of the class created
