I had create the GUI program. I used the file chooser in my program. I want to select the multiple files so that all the files chosen is appear in the TextArea. My problem is, I can select the multiple file from the file chooser but after i click the open button, only one file is appear in the TextArea. Howcan I put the multiple files into the TextArea. Below is my code of the file chooser.



[code]
private void browse1ActionPerformed(java.awt.event.ActionEvent evt) {
JFileChooser fileChooser = new JFileChooser();
fileChooser.setMultiSelectionEnabled(true);
int returnValue = fileChooser.showOpenDialog(null);
if (returnValue == JFileChooser.APPROVE_OPTION) {
File selectedFiles = fileChooser.getSelectedFile();
plain1.setText(selectedFiles.getName());
}
}
[/code

Are you wanting to append the multiple files in the same area? (needed clarification)

You called the method that returns only 1 file
If multiple selections is enabled you should call the other one
CODE

// this return the first selected file
File selectedFile fileChooser.getSelectedFile();

// this one (notice the ending S) returns an arrayof the selected files
File[] selectedFile fileChoosergetSelectedFiles();

// then you can
for(File f : selectedFile) {
    textField.add(f);
}


hope this help

thanks for helping. I had try to put the code. but still not work. i tried to put the
CODE
plain1.add(f);
The plain1 is the TextArea.

You mean that the add function is to add the other files?

try

System.out.println("Number of file sleected: " + selectedFile.length());
for(int i = 0; i <  selectedFile.length; i++) {
    System.out.println("Adding: " + fileSelected[i] + " as file " + i);
    plain1.append(fileSelected[i].toString + "\n");
}

at least you'll see if you selected the good number of files and extracted their name correctly
not 100% sure what add(object) to a textArea does
