thanks masijade,
i have filter the file chooser for only text files,
but i still don't know how to use FileReader to put text file content to the text area (ta) ..
please tell me how and where to use it..How? -- See the IO Tutorials on Sun for the FileReader (and I assume you know how to call setText and append in the JTextArea).
Where? -- In the actionPerformed method (better would be a separate thread that is triggered through the actionPerformed method, but that is probably beyond you at the moment), of course.
Give it a try.
