Show output on jTextArea

Hi there, hope you can help me, this is a program made in Netbeans.

In the attached image, I have a JMenuItem called "Listagem de ficheiros" with an ActionEvent.
Attachment 1286

I want to click on it and open a jTextArea that returns the output of next code:

PHP Code:

---

File folder = new File("C:\\Users\\Hugo Monteiro\\Documents\\NetBeansProjects\\FileImporter\\ImagensDB");  
         File[] listOfFiles = folder.listFiles();  
         for (int i=0; i<listOfFiles.length; i++) {  
             if (listOfFiles[i].isFile()) {  
                jTextArea1.append("File: " +listOfFiles[i].getName().split("-"));  
        }  
      }

1 - i can't make it open a jTextArea to show the output.
2 - It doesn't split the file name

normal Output: 001-A Retro Autumn-Garnett Rules-MAI2012-24.45-Landscapes.jpg
What i want: 001 A Retro Autumn Garnett Rules MAI2012 24.45 Landscapes.jpg

Thanks in advance.

BTW i think the code as to be inside:

Code :

---

private void jMenuItem6ActionPerformed(java.awt.event.ActionEvent evt) {                                             
   //código para Output  
 
    }

---

this action performed is from "Listagem de ficheiros", the onde that makes the output

File folder = new File("C:\\Users\\Hugo Monteiro\\Documents\\NetBeansProjects\\FileImporte r\\ImagensDB");
File[] listOfFiles = folder.listFiles();
for (int i=0; i<listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
jTextArea1.append("File: " +listOfFiles[i].getName().split("-"));
}
}

While it's allowable, somehow, probably it calls the array's toString, to use the split, which returns an array, you're going to have the word "File: " + a bunch of silly characters that is a String array toString. Probably not what you wanted.

Also, as far as I know, you can't just "open" a JTextArea itself. I think you need a JFrame or something similar to do that.

As for the JMenuItem, you could simply use the addActionListener() method.

split("001-A Retro Autumn-Garnett Rules-MAI2012-24.45-Landscapes.jpg") is returning a String array

String[] tempArray = split(.......);
tempArray[0] = "001";
tempArray[1] = "A Retro Autumn";
tempArray[2] = "Garnett Rules";
tempArray[3] = "MAI2012";
tempArray[4] = "24.45";
tempArray[5] = "Landscapes.jpg";

You could instead just use the replaceAll() method. Using the split() method, as stated above, will return an array of strings.
