Drawing Memory

Consider the following:

What does memory look like after running the following?

Circle c = new Circle("example");

Diagramming a Class

Create a UML Class Diagram for a class to represent a GPS coordinate. You should be able to compute the distance between two points and which of a pair of points is farther from sea level.

Solution from lecture:

--------------------------------------
           GPSCoordinate
--------------------------------------
lat: double
lon: double
alt: double
SEA_LEVEL: static final double       // section 001 didn't have SEA_LEVEL
--------------------------------------
GPSCoordinate(double, double, double)
distance(double, double) : double    // section 001 didn't have this version
distance(GPSCoordinate) : double
fartherUpThan(GPSCoordinate) : boolean
--------------------------------------
