The usual assortment of get/set methods are declared to return or change the values of the
location and velocity of the rocket and to return or change the values of the fields declared in
the
SimpleRocket
class. Not all of the get/set methods are shown here.
// These methods return the value of the fields.
public double getVx() {
return getQ(0);
}
public double getVy() {
return getQ(2);
}
// Other get/set methods not shown ...
