Java recognizing address information and breaking it apart into variables (no regex)

Does anyone have a recommended pseudo-algorithm for, given a string containing an address:

Bre开发者_开发百科ak apart the address apart into a Street variable, a City variable, a State variable, and a Zip variable

The address string may be formatted in a number of different ways. For example, it may be comma separated or it may be separated by spaces. Also, the address may only contain a city and state, and not a street address or zip code. Similarly, it may contain a street, city, state, and not a zip code.

To make things harder, I cannot use regular expressions (as I am developing on a mobile platform that does not support it).

Thanks!

No, but look at JGeocoder:

They split addresses up into their constituent parts. You could take a look at the source for that...
