Parsing Text file

Dec 1st, 2005

Alright, This is really bothering me that I can't figure this out since I took 3 terms of Java.

Alright, I have a text file that contains addresses.

ex:
Name
1234 5th St
Orlando, Fl 19191

Name2
1423 4th ave
New York, NY 09987

and so on and so on.

Originally I was trying to have it take each line and put it into an 2d array.

addyArray[addyIndex][lineOfAddy].

I could not figure out how to make a linebreak (gap) be the delimiter to separate the values.

Most of the addresses will be 3lines, but I wanted the expandability of being able to handle 4 line addies.

Can anyone help me with this? If you need more details either post in here or email me at nscelica@yahoo.com.

Thanks

You can try the StringTokenizer which allows special delimeters. Also, I'm not sure a 2D array is the best way to go, but can't say for a fact that it's not. If you post your parsing code we could probably help more.
