The following class definitions are stored in separate files: 
public class One
{
   public int getVar()
   {  return var;
   }

   public void setVar(int theVar)
   {  var = theVar;
   }

   private int var;
}

public class Two
{
   public static void main(String[] args)
   {  One obj = new One();
      System.out.println(obj.getVar());
   }
}
When we compile them, what problem(s) (if any) will there be?

(a) The compiler will complain that var isn't initialised.
(b) The compiler will complain that the program tries to access var, which is private.
(c) The compiler will say that var is local to the method getVar() and therefore cannot be used in method setVar().
(d) There are no problems.
