Why do I keep getting an "illegal start of expression error" for my method.

Question

This is my code if you could please take a look.

////////////////////////////
Separate File
/////////////////////////////
public class BirthDate
{
// Attributes
private Integer month;
private Integer day;
private Integer year;

// Constructor
public BirthDate(Integer m, Integer d, Integer y)
{
this.month = m;
this.day = d;
this.year = y;
}

// toString
@Override
public String toString()
{
return month + "-" + day + "-" + year + "-";
}

// Equals method
public boolean equals(BirthDate bd)
{
return this.month.equals(bd.month) && this.day.equals(bd.day) && this.year.equals(bd.year);
}
}
/////////////////////////
Main method
////////////////////
import java.util.*;

public class BirthdayParadox
{
public static void main(String[] args)
{
ArrayList<BirthDate> bd = new ArrayList<>();
Scanner keyboard = new Scanner(System.in);
Random randomNumbers = new Random();
int birthdates;
int x = 0;

System.out.println("How many birth dates would you like to check? ");
birthdates = keyboard.nextInt();
createBirthDates(birthdates);

// Method to create BirthDate objects
public static BirthDate createBirthDates(int num)
{
do
{
int m;
int d;
int y;

m = randomNumbers.nextInt(12) + 1;
d = randomNumbers.nextInt(31) + 1;
y = randomNumbers.nextInt(2020);

bd.add(new BirthDate(m, d, y));
}while (x < num);
}
}
}

Any help is welcome. Thanks!

Answer 1

you are declaring createBirthDates() inside main()
do it outside as separate method

public static void main(String[] args)
{
}
public static BirthDate createBirthDates(int num)
{
}

Thanks. I finally got it to work.
