Java Tutorial/2D Graphics/Dimension

java.awt.Dimension

1. A Dimension object represents a width and a height in int.
2. The getWidth and getHeight methods return a double, not an int.
3. You can construct a Dimension object by using one of its constructors:

public Dimension ()
public Dimension (Dimension d)
public Dimension (int width, int height)

The no-arg constructor create a Dimension with a width and a height of zero.
