What is the effect of attempting to compile and run this Java program that consists of two class definitions in separate files: 
public class One
{
   public One(int theVar)
   {  var = theVar;
   }

   public void 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(26);
      obj.getVar();
   }
}
(a) The program compiles and, when run, displays 0 (zero) on the screen.
(b) It compiles and, when run, displays 26 on the screen.
(c) It compiles and, when run, displays nothing on the screen.
(d) It doesn't compile.
