in our Eclipse IDE we are using window builder we have a class with a method to uploadcsv file from our hard disk the csv file has $10$rows and $3$ columns, the columns are row number, question string, answer string. we want to upload the csv file when a button is clicked and display its content in the JTextArea of the dialog box and then when a button is clicked we want to append this csv file to the csv file we have stored on our hard disk. We tried implementing the above method but unfortunately the content of the csv file is appearing on the console instead of the dialog box also when we click on submit to append the csv file we get a bunch of errors $.$ please explain with an example how can we resolve this
