/////////////////JAVA PLEASE/////////////////////////////////

Create a class called GVdate to keep track of a calendar date including month, day and year. You can do simple things like checking if it is your birthday, advancing to the next day, checking if a given date is valid and checking if it is a leap year.

Class Fields/Instance Variables

Provide appropriate names and data types for each of the private instance variables:
- the month, day and year (int)
- two final integers that represent YOUR birthday (month and day)

Constructors

public GVdate( )– this is the default constructor; it assigns the following initial values to the instance variables:
- month: 10
- day: 12
- year: 2020
public GVdate (int m, int d, int y) – set the instance variables to the provided input parameters. For now, assume that the input parameters are correct.

Accessor Methods

public int getMonth( ) – return the month.
public int getDay( ) – return the day.
public int getYear( ) – return the year
public String toString() – return a formatted date string (for example "10/12/2020").
public boolean isMyBirthday () – return true if the date is YOUR birthday. Otherwise return false.

Mutator Methods

public void setMonth(int m)- set the month to the input parameter. For now, assume the value for the month will not create an invalid date.
public void setDay(int d)- set the day to the input parameter. For now, assume the value for the day will not create an invalid date.
public void setYear(int y)- set the year to the input parameter. For now, assume the value for the year will not create an invalid date.
public void setDate (int m, int d, int y) – set the instance variables to the values of the input parameters. For now, assume the values of the input parameters will not create an invalid date.

   }

       this.calDate=d;
       this.calMonth=m;
       this.calYear=y;

   }

   public boolean isDateValid() {
       String dateStr=toString();
DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(false);
try {
sdf.parse(dateStr);
} catch (ParseException e) {
return false;
}
return true;
}
   public boolean isLeapYear() {
boolean leapYear = false;

if(calYear % 4 == 0)
{
if( calYear % 100 == 0)
{
if ( calYear % 400 == 0)
   leapYear = true;
else
   leapYear = false;
}
else
   leapYear = true;
}
else
   leapYear = false;

return leapYear;
   }
   public Date advancingtonextday() {
       Calendar c = Calendar.getInstance();
       DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
sdf.setLenient(false);
Date currentDate = null;
try {
   currentDate=sdf.parse(toString());
} catch (ParseException e) {

}
       c.setTime(currentDate);
       c.add(Calendar.DATE, 1);
       Date newDate = c.getTime();
       return newDate;
   }

   public int getCalDate() {
       return calDate;
   }
   public void setCalDate(int calDate) {
       this.calDate = calDate;
   }
   public int getCalMonth() {
       return calMonth;
   }
   public void setCalMonth(int calMonth) {
       this.calMonth = calMonth;
   }
   public int getCalYear() {
       return calYear;
   }
   public void setCalYear(int calYear) {
       this.calYear = calYear;
   }
