Overloaded Methods

a) In this chapter’s Height class modify the two-parameter setHeight method to see if the units value is one of the following: “in”, “ft”, “mm”, “cm”, or “m.” If it is, update the units field and return the boolean value, true. Otherwise print “Unrecognizable units: ” and return false.

b) Modify the corresponding HeightDriver class so that it calls the Height’s print method only if a previous call to the two-parameter setHeight method returns true.
