How can I make the date in number format look like 01/21/2018 instead of the output below which comes out as 21/01/118

import java.util.*;

public class date {

/*

* this method increases given date by one day.

* */

@SuppressWarnings("deprecation")

public void increaseDate(Date d){

d.setDate(d.getDate()+1);

System.out.println("Date after increment by one day");

System.out.println(d);

}

/*

* this method prints date in number format

*

* */

@SuppressWarnings("deprecation")

public void printDateInNumber(Date d)

{

System.out.println("Date in Number format");

System.out.println(d.getDate()+"-"+d.getMonth()+1+"-"+d.getYear());

}

/*

* this method prints date in string format

*

* */

public void printDateInString(Date d)

{

System.out.println("Date in String format");

System.out.println(d.toString());

}

/*main method will be the steps for the program to ask for the information that the other method will implement.

*

*

*/

@SuppressWarnings("deprecation")

public static void main(String[] args) {

date d=new date();

int day,month,year;

Scanner scan=new Scanner(System.in);//for input form user

System.out.print("enter Date in DD Format:-");

day= scan.nextInt();

System.out.print("enter Month in MM format:-");

month= scan.nextInt();

System.out.print("enter year in YYYY format:-");

year= scan.nextInt();

scan.close(); //close the input channel

Date thisDay=new Date(); //create a current date instance

//set date to given inputs from user

thisDay.setDate(day);

thisDay.setMonth(month-1);

thisDay.setYear(year-1900);

//display date in number format

d.printDateInNumber(thisDay);

//display date in string format

d.printDateInString(thisDay);

//increase the date by one day

d.increaseDate(thisDay);

}

}
