Thread: Getting error message and can not figure it out.

I have been working on this assignment for 2 days now and I have had this error message. I hope a fresh set of eyes will help me.
Here is my code

import javax.swing.JOptionPane;
 
//Louis Friedmann
//July 09, 2013
//This program prints the output in dialog boxes
 
 
 
 
public class DateJDialog
{
 
	 public static void main(String[] args) {
 
 
	         //Variables Declaration
	         String inputString; //input
	         int dayIs;  //day
	         int yearIs; // year
	         int monthIs; //month
	         String leapResult; // tell's whether it's a leap year or not.
 
	         //Input
	         inputString = JOptionPane.showInputDialog("What is the day?");
	         dayIs = Integer.parseInt(inputString);
 
	         inputString = JOptionPane.showInputDialog("What is the month?");
	         monthIs = Integer.parseInt(inputString);
 
	         inputString = JOptionPane.showInputDialog("What is the year.");
	         yearIs = Integer.parseInt(inputString);
 
	         //calculation
	         if (isLeapYear(yearIs))
	         {
	             leapResult = " is a leap year";
	         } else
	         	{
	             leapResult = yearIs + " isn't a leap year";
	         	}
 
	         //output
	         JOptionPane.showMessageDialog(null, leapResult);
 
	         //exits the program
	         System.exit(0);
    }
 
 
}

And this is my error message:

C:\Users\Friedmann\Desktop\Java\Assignment 5\DateJDialog.java:34: error: cannot find symbol
if (isLeapYear(yearIs))
^
symbol: method isLeapYear(int)
location: class DateJDialog
1 error

Tool completed with exit code 1

Please help!!!!!!

Thanks.

I can't find the isLeapYear(int) method in your code. Since each method must be defined in the class or statically imported before being called, and you calls the undefined method in your code, the compiler of course will throw an error. To solve this problem, you need to add the definition of the static method isLeapYear(int) to the class body. As to how to decide wether it is a leap year or not, I think it's not hard for you to figure out.
