 /**

  * when referring to return type
  */
  //public means who can see/call this method, 
  //Dimension2D is the return type
  //getDimension is the method name.
  public Dimension2D getDimension(){
    return new Dimension2D(2,2);
  }


/**
 * 
 * When we refer to objects we are refering to
 */
//typeofobject  object        classconstructor(parameters)
  Dimension2D demObject = new Dimension2D(2,2);
  
/**
 * 
 * When we are refering to a method 
 */
 //first create a object
 EllShape s = new EllShape(b);
 
 //then use a method
 s.rotate();
 
//1. I am wondering what Dimension2D getDimension(); returns. What do the object's dimensions mean? 2D? 
@Override
 public Dimension2D getDimension() {
 	// the main objective is to find the the longest line of consecutive
 	// blocks(in both x[left & right] and y[up & down] directions) within your shape array
	// **this will vary amoung everyones program**
	// but one way of doing it is to loop through your 2d array finding Block objects that are next to eachother  
	// after you have your x and y
	// y = height, x width
	Dimension2D demObject = new Dimension2D(y,x);
	return demObject;
}
//2. What does getBlockAt(int row, int col) mean? 
@Override
public Block getBlockAt(int row, int col) {
	//from what I understand it checks to see if the block exists
	// if row and col are valid points within the shape return the block
	//if not return null
	return new Block();
}

//3. I initial a Block[][] to store the shape like Block[][] block = new Block[5][5];. If I want to use variants, not a fixed value, to control rows and columns. How can I do that?

//well this is a little complex you may have to elabortate on what you mean.
