solved na bro. heheh tnx ninyu

Ani ni siya jairoh...nganong 9 na siya.
9 is the value used to determine the kana nga Character kay digit na. (short cut).
Nganong 9 is sila ray gaboot, you could have used any value.
Nganong int type gigamit kay, ang switch case sa Java int raman dawaton.
This is for code writing purposes not for algorithm or analysis purposes.
Indicator variables in Java are usually int para ma take advantage ang mga conditional statements nila.
Lastly, makabantay ka CAPITAL na sila pirmi.

Codewise murag ingani.

public class Dog{
    public static final int IS_WALKING = 1;
    public static final int IS_URINATING = 3;
    public static final int IS_STAYING = 0;

    public int dogState = 0;
       
    public Dog(){
    }
   

    public void stay(){
        //do stopping algorithm
        dogState = IS_STAYING;
    }

    public void walk(){
       //do walk algorithm
       dogState = IS_WALKING;
    }

    public void urinate() throws DogCommandException{
         //MAO NI ANG SIMILAR SA ==9 IN THIS CASE ANG VARIABLE 
        //ANG KANINDOT ANI SAYON SIYA BASAHON CODEWISE
          if(dogState == IS_WALKING){   GIGAMIT
              throw new DogCommandException("Cannot urinate while walking"); 
          } else{
             while(dogState == IS_URINATING){
                //do urinate algorithm, raise legs, optional halhal
                dogstate = IS_URINATING;
                if(Kidneys.isEmpty(this)){
                     dogstate = IS_STAYING;
                } 
             }
             
          }  
           
    }


}

public class DogTrainer extends DogOwner{
    public static void main(String args[]){
         Dog myDog = DogTrainer.callDog();
         myDog.bark();
         myDog.walk();
         try{
         myDog.urinate();
         } catch( DogCommandException e){
               System.out.println(e.getMessage());
               myDog.stay();
               myDog.urinate();
         }
    } 
}

So this is a short code to demonstrate the use of STATIC VARIABLES with INT values.
Though nindot ta nga example kung SWITCH CASE kay kita gyud ang beauty niya.
This short code also demonstrates the use of try catch.
It is when you are expecting and/or attempting to contain an error to respond to it any manner.
In this case, pag tawag nako og URINATE while WALKING dili man pwede, so mo error siya expectedly.
so akong gi-try catch para madakpan ang error, unya i-execute ang sakto ng code.
Furthermore Exception Objects are used to show more information about any given Error or Exception.
Hope makatabang ni.

TS, naa pa ko code oh...
simple and easy to read and understand...
i know if gamiton ni sya sa Data Structure hagbong ni tungod sa performance issue... but still it performs what is asked and dali ra sabton kay by methods man ni sya...

i hope maka tabang ni ako tampo nimo... hehehe
