title: Java system.out.print to print JOptionPane.ShowMessageDialog
body: <p>How can I print system.out.print message into a JOptionPane.ShowMessageDialog I need it to run through the for loop and then outside the for loop I need it to display inside of a JOptionPane.ShowMessageDialog box. I am really crunched for time. I would greatly appreciate any help. Thank You!</p>
