title: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
body: <p>I have written this code to fetch data from jTable and show it on the console, but I am facing an error (Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException). Please tell me what condition I should use to get rid of it. I want to check if the next entry of jTable is empty then come out of loop.
