grabbing a line of text if you know the start and finish

[neu]

I have a text position and I would like to grab 100 characters before this
point and 100 charcters after this point.
Using indexOf(text) , how can I manipulate to see what 100 characters is
before the indexOf(text) result.?

For pity's sake neu/JV, did you try RTFM?
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#substring(int,
int)
The substring method is mentioned in the
description of the class.

Java has instructions, try reading them before
wasting our time, eh?

int idx = myString.indexOf(text);
myString.substring(Math.max(0,idx-100), idx);
