Java Abstract Classes

Can anyone tell me if this is correct when creating classes in Java?

Code:

public abstract class Animal
{
   public class Point
   {
      public int x,y;
   }  
   public class Animal
   {
      protected Point loc;
      protected String name;
      protected Random rng;
      String getName()
      {return name;}
 
      Point getLocation()
      {return loc;}
 
      void setStartLocation(Point p)
      {
      }  
      Animal( String name, Random rng )
      {
         this.name = name;
         this.rng;
      }  

      void move()
      {
      }  
   }

 public class Cat extends Animal
     {
      }

Do I put anything under void setStartLocation and void move? This is for a game where a cat is chasing a mouse on a island(grid).

Another thing I am not sure of is how would I override the move method to randomly move north, south, east or west under the Cat class. Would it be something like move.random()?

Thank you for any help.

evwatcher

EVWATCHER(3)								 1							      EVWATCHER(3)

The EvWatcher class

INTRODUCTION

       EvWatcher  is a base class for all watchers( EvCheck , EvChild etc.). Since EvWatcher 's constructor is abstract , one can't(and don't need
       to) create EvWatcher objects directly.

CLASS SYNOPSIS

       EvWatcher

       abstract
       EvWatcher

       Properties

       o public$is_active

       o public$data

       o public$is_pending

       o public$priority

       Methods

       o public int EvWatcher::clear (void  )

       o abstractpublic EvWatcher::__construct (void  )

       o public void EvWatcher::feed (int  $revents)

       o public EvLoop EvWatcher::getLoop (void  )

       o public void EvWatcher::invoke (int  $revents)

       o public bool EvWatcher::keepalive ([bool  $value])

       o public void EvWatcher::setCallback (callable  $callback)

       o public void EvWatcher::start (void  )

       o public void EvWatcher::stop (void  )

PROPERTIES

	      o $is_active
		- Readonly .  TRUE if the watcher is active.  FALSE otherwise.

	      o $data
		- User custom data associated with the watcher

	      o $is_pending
		- Readonly .  TRUE if the watcher is pending, i.e. it has outstanding events, but its callback has not yet  been  invoked.   FALSE
		otherwise. As long, as a watcher is pending(but not active), one must not change its priority.

	      o $priority
		-  Integer  between  Ev::MINPRI  and Ev::MAXPRI . Pending watchers with higher priority will be invoked before watchers with lower
		priority, but priority will not keep watchers from being executed(except for EvIdle watchers). EvIdle watchers provide functional-
		ity to suppress invocation when higher priority events are pending.
