Java and Database Connectivity: Slide 34

Java and Database Connectivity

A bit about syntax: declaring a method

    /** just a blob round my end position */
    public void paint( Graphics g)
    {
    	g.setColor( colour);

    	g.fillOval( end.x - radius, end.y - radius, 
		    2 * radius, 2 * radius);
    }

Methods are the way we describe the behaviour of objects. Here is a methd called paint which describes how a BlobHand paints itself on a Graphics object.
- It calls a method setColor of the Graphics object to set the colour it wants.
- It calls a method fillOval of the Graphics object to draw a filled circle at its end position
public means that any other object can call this method
void means that this method doesn't return any value
