Displaying first 3 lines of a variable
Hello,
I am working on a JSP search script. I have a list of results displayed after a search is run, with each individual result only displaying the first 195 characters of the results body text. Instead of using the following code.... shortBody = ad.getBody().substring(0, 195) .....I want to make the shortBody pick out the first three lines, rather than the first 195 characters. Is that possible? Thanks, Ida

I've no idea how efficient this will be but it does the trick. It basically finds the third occurrance of '\n' and gets a substring from 0 to it. I'm assuming that shortBody and ad are Strings.
Code:
shortBody = ad.getBody().substring(0, ad.indexOf("\n", ad.indexOf("\n", ad.indexOf("\n") + 1) + 1)) ;
