Cannot find symbol?

Apr 2 '11, 10:03 PM

I know this should be a simple fix but I can't figure it out. This is my class that generates the factors for a given number. It works until I try to use the return, in which it says cannot find symbol: variable a, even though it has been declared. I bolded the line the error is on. Any help?

Code:

import java.util.Scanner;
public class FactorGenerator 
{       
                public static int initialNumber;
         
             public FactorGenerator()
             {
                 for (int a=1; a < initialNumber; a++)
                 {   
                      if(initialNumber%a == 0)
                      {
                       
                        System.out.println(a + " ");
                      }
                 }
             }           public static int getFactors()
                         [B]{
                         return (a +"");
                         }[/B]                [CODE]

}[/CODE]

variable a is inside the scope of for loop. So it will not be available out side the loop. As you can see you are trying to access the variable in a getter method.

You can use the class variable for this purpose or any other means of data retrieval. But obviously you can not use variable which is not in scope.
