Instead of using JTextArea setText String text   use JTextArea append String text       Appends the given text to the end of the document  Does nothing if the model is null or the string is null or empty     This will add text on to the end of your JTextArea   Another option would be to use getText   to get the text from the JTextArea  then manipulate the String  add or remove or change the String   then use setText String text  to set the text of the JTextArea to be the new String
