JAVA GUI : How to use button listener to read and display text file?

• What i want to happen in my program is when the button is clicked, it will initiate a button listener to read a text file and display the text in a dialog box. Can anyone give examples on how to do this?

• Answer:

  Are you planning some thing like editor? May be in your actionPerformed method you can write the following assuming A is an TextArea type of global object public void actionPerformed(ActionEvent E) { Scanner S= new Scanner(new File("filename")); while(S.next()) { String L=S.nextLine(); A.append(L); or A.add(L); } }
