Hi. Im my web app, I want to get the newer five books from the database and display them in the index page. At the index page, the title of the book should be displayed and a snippet of its description (lets say, the first 100 chars of its descripton). Good example: This book is written by .... <link>Read More</link> Bad example : This book is writ .... <link>Read More</link> Do you see the problem ? When I substring the description text, the whole last word should be included in the snippet not part of it. Here is my small algorithm : - use substring(0, 150) - if the last character is a white space, then substring (0, 151) - repeat Do you suggest a better solution ? :roll:
I would convert the text description to a char, then, starting at 150, back down the char looking for a good end of word indicator - space, punctuation, etc. or reaching some minimum - say 120. With that index, create a new String.
This saves all that extra String object creation and lets you use characters besides whitespace as delimiters/
