Question

I have a question,

Implement a class Address. An address has a house number, a street, an optional

apartment number, a city, a state, and a postal code. Supply two constructors: one with an apartment number and one without. Supply a print method that prints the address with the street on one line and the city, state, and postal code on the next line. Supply a method public boolean comesBefore (Address other) that tests whether this address comes before another when the addresses are compared by postal code.

I have written the program but am stuck on this part. Supply a method public boolean comesBefore (Address other) that tests whether this address comes before another when the addresses are compared by postal code.
