Reading file

Design a GUI application as shown below and perform the following tasks:

The text field is for data file name, the length of file name should be between 5 and 10, and file extension must be .txt, otherwise, prompt user to provide a valid file name.

Load the content of the data file and display on the textarea. WITHOUT USING bufferedreader.

this is what i was thinking at least how to get to the file

private void loadFile() { File file;

String fileName = field.getText();

file = new File(fileName);

Loading Files File Name: data.tt Load File
