Need to use an int in a different class

EDIT: Problem solved.....feel free to delete this thread

I have a very basic question:

I have 2 classes; GUI.java & learner.java. The GUI contains a method that is called when it runs that shows an inputDialog , and the user chooses a number between 2 & 10.

Code:

public void setNumChars()throws Exception{
   int tmp;
   do
       tmp = Integer.parseInt(JOptionPane.showInputDialog("Write 
       num of chars\nbetween 2 and 10:"));
        
   while(tmp>10 || tmp<2);
     
   numChars = tmp;
}

And I need the number that the user inputs to be available to me in the learner.java class. So I tried creating a public method that retrieves the number (it is also located in the GUI class):

Code:

public int findNumChars(){
   return numChars;
}

Then I tried using that method in the learner class.

Code:

public static void learn(String tekst, int orden)
        {
        ....................
        for(int i=0; i<=tekst.length()-(findNumChars() -1); i++)
            {
           ...........................
            if
                ....................
            else
                ..................
            
            }
            
        }

Now, I know that this doesn't work. My question is; what changes do I have to make to be able to use the user-inputted int from the GUI, in the learner class?

Really appreciate your help, thanks

Can you please post your solution for future reference?

I know it either involves setting a global variable to using a set method in the learner class, but let us know which you used.
