Calling A.method() which instanced B from Instance A, B is of another class

Question

I have a class that creates a window. In the process of adding a mouse listener to a pane of labels in that object I am not able to create and action on left click of the label due to not being able to access the method of the Calling class
public class A
     A(){
     JPanel MainBar = new JPanel();
      B b = new B( this );
         b.setB(x, y, anArray );
public void changeIcon( int xL, int yL, int ind )
            switch ( ind )
                case 0:
                    if ( jlblButtons[xL][yL].getIcon() == icon[0] )
                        jlblButtons[xL][yL].setIcon( icon[1] );
                        ButtonPanel.repaint();
                       GroupClear instance_of_clear = new GroupClear();
                        instance_of_clear.groupClear( xL, yL, x, y );
public class B
       public int[][] anArray;
       public int x;
       public int y;
          A e;
       B(A e){
             this.e = e;
       public void setB(int x, int y, int[][] anArray )
           this.anArray = new int[x][y];
           this.anArray = anArray;
       public void mousePressed(MouseEvent e) {}
       public void mouseReleased(MouseEvent e) {}
       public void mouseClicked(MouseEvent e)
           String location = e.getComponent().getName();
           x = Trim.trim( Trim.Left( location, 2 ));
           y = Trim.trim( Trim.Right( location, 2 ));
           if ( e.getButton() == MouseEvent.BUTTON1 )
               switch ( this.gameArray[x][y] )
                   case 0:
                      e.changeIcon( x, y, 0 );
                      return;
}It calls the get Icon, but the compiler cannot find e.changeIcon
I have also tried to send the calling class like this
b.setB(x, y, anArray );
       public void setB(int x, int y, int[][] anArray, B e)
           this.anArray = new int[x][y];
           this.anArray = anArray;
              this.e = e;
       }But to no avail. What will I need to do in order to properly call the function of the class that called B?

Answer 1

What exactly do you want to call and where?
You can't call e.changeIcon() from mouseClicked because e is MouseEvent, and (in the second piece of code) you can't assign an instance of type B to a field of type A.
