Bug: New GUI Functionality: Pressing Encrypt with no input causes Exception #31

Closed EOhlmacher closed 10 years ago

EOhlmacher commented 10 years ago

Steps to reproduce:

  1. Launch new GUI
  2. Press "Encrypt"
  3. Alternatively, enter only a special character such as $

Observed Result: Exception in thread "AWT-EventQueue-0" java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.charAt(Unknown Source) at main.java.GUINew.Lightboard.turnOnLight(Lightboard.java:263) at main.java.GUINew.IOPanel$EncryptButtonListener.actionPerformed(IOPanel.java:231)

Expected Result: No assert. The output text box should read "Input text must contain at least one letter or number." per the EncryptButtonListener class.

Resolved by checking for empty string in lightboard.
