Question

Write your answer in the space provided or on a separate sheet of paper. Date Co Design a class called Date. The class should store a date in three integers: month, day, and year. There should be member functions to print the date in the following forms: 12/25/201 December 25, 201 25 December 2014 Demonstrate the class by writing a complete program implementing it Input Validation: Do not accept values for the day greater than 31 or less than 1. D not accept for the month greater than 12 or less than 1

Explanation / Answer

In the below progeam I have created a class called Date. I used a parameterized constructor to pass 3 parameters, month,day and year; I have created a printDate() function to print the date in requested format. In printDate(), before printing the date I am checking for validation. For validating date I have created a seperate function validateDate() , which return true or false on validation. Date is printed only if validateDate() returns true For getting month name for a particular month I have created another function called getMonth() which returns month name based on month number.

Below is the entire code for the program:

import java.util.*;
import java.lang.*;
import java.io.*;

class Date
{
    int month, day, year;
    Date(int month, int day, int year){
        this.month = month;
        this.day = day ;
        this.year = year;
    }

    Boolean validateDate(){
        Boolean flag;
        if(this.day>31){
            System.out.println("Day cannot be greater than 31");
            flag=false;
        }
         else
         flag=true;
        if(this.month<1 || this.month>12){
            System.out.println("Month must be greater 0 and less than 13");
                flag=false;
        }
            else
                flag=true;
        return flag;
    }
    String getMonth(){
        if(this.month==1)
            return "January";
        else if(this.month==2)
            return "February";
        else if(this.month==3)
            return "March";
        else if(this.month==4)
            return "April";
        else if(this.month==5)
            return "May";
        else if(this.month==6)
            return "June";
        else if(this.month==7)
            return "July";
        else if(this.month==8)
            return "August";
        else if(this.month==9)
            return "September";
        else if(this.month==10)
            return "October";
        else if(this.month==11)
            return "Novermber";
        else
            return "December";
     
    }
    void printDate(){
        Boolean flag = this.validateDate();
        if(flag){
        System.out.println(this.month+"/"+this.day+"/"+this.year);
        System.out.println(this.getMonth()+" "+this.day+","+this.year);
        System.out.println(this.day+" "+this.getMonth()+" "+this.year);
        }
    }
  
   public static void main (String[] args) throws java.lang.Exception
   {
         Date d = new Date(12,25,201);
         d.printDate();
    }

}

Plese give a thumbs up if you liked the solution.
