Calling a class from one jinternalframe to another

Question

I have two jinternalframe in a java project JF1 and JF2.

I have created a class named as insert_in_JF1, now I want to call this class from JF2 by passing some parameters.

Is this possible?

JF1 like this where Insert is a class and InsertValues() is a method now i want to call this method from JF2

public class Insert extends javax.swing.JInternalFrame {                                            
   public void InsertValues()
   {
       JOptionPane.showMessageDialog(this, "Working");
   } 
}
