                  //I have doubt in here 
                  // i created a dog Object then how can d.getCollar().getCollarSize() 
                  // be used in here, getColorSize is from Collar class??
  }
}

[Edit - fixed line breaks]

[Winston Gutkowski]

I finally found your question embedded in your code. Could you please edit your post and move it outside the code block?

Because it makes an enormously long line, which screws up the window formatting here and makes everything
else very difficult to read. I'll be happy to answer your question when you've done that.

Thanks.

done the corection

You are returning a reference to a Collar object, whose getCollarSize() nethod you are calling.
Your getCollarSize method is inappropriately names; it ought to be getSize, and the field ought to be called size.

You would do better to put a getCollarSize() method in the Dog class.

public int getCollarSize()
{
   return collar.getSize();
}
