static int: How do I change it from a subclass?

2013/6/27

Hello there, I need help changing the int rn from my subclass 'Groundside'; here are my classes(Placer, Ground & Groundside). Placer:

public class Placer extends GifActor
{
    static int rn;
    static int gsy;
    static boolean rnc;
    
static boolean getRNC()  
{  
    return rnc;  
}  
static void setRNC(boolean type)  
{  
    rnc = true;  
}  
public void act() 
{          
}
}

Ground:

public class Ground extends Placer
{
    boolean costume;
    boolean random=false;

public void addedToWorld(World world)  
{
        gsy= getY();
        setImage("building2.gif"); 
}
    public void act() 
{
        super.act();
    setLocation(getX() - 4, getY());
        boolean random=false;
    {
      rn=Greenfoot.getRandomNumber(300)+200;
        {
        if (getX()<10)
        {           
            setLocation(590,rn);
            rnc=false;
        }
        if(getX()>10)
        {
            rnc=true;
        }
        if (getY()>275)
        {
            setImage("building2.gif");
        }
        else if(getY()<275)
        {
            setImage("building1.gif");
        }
        if(getY()<275)
        {
            setLocation(getX(),270);
        }
    }
}
}}

and finally, Groundside:

public class Groundside extends Placer
{

public void addedToWorld(World world)  
{

}
static boolean getRNC()  
{  
    return rnc;  
}  
public void act() 
{
        setLocation(getX() - 4, getY());
        boolean random=false;           
{
        {
        if (random=true&&rn<200)
        {
            random = false;
        }
        if (getX()<10)
        {
            setLocation(590,rn);
            random=true;
        }

}
}}}

I am trying to change the static int 'rn' from the subclass 'Groundside'
