Involves three things:

1. Creating the reference: Box thisBox ;

2. Instantiating the object: thisBox = new Box( );

OR do first two steps at once, e.g.,

Box thisBox = new Box( )

3. Having constructor(s) set initial values:

public Box (int iNewLength, int iNewWidth, int iNewHeight)

{

setLength (iNewLength);

setWidth (iNewWidth);

setHeight (iNewHeight);

} // of constructor

With an appropriate constructor, we can

do all three at once:

Box thisBox = new Box (10, 5, 25);
