Populating a gui list box with the files in a directory

I need to populate a list box with the names of a directory files.
For example
I have a folder called x. In that folder there is the following files
1.csv
2.csv
3.csv

Now I need to populate the my gui list box to populate fields with
1.csv
2.csv
3.csv

Here is my code so far
Public class dir{
File folder = new File("c:/mydocument/");
File [] listofFiles=folder.listFiles();
}

Now that I have the lisofFiles
how do i pass the values to my main gui class

An example code would be greatly apreciated.
}

You are correct in the listing of the files. The following solution assumes that a GUI list box is a JList.

If you look under the Java API for JList you will find a method called setListData... this is the method you are looking for.

The following is a quick preview of what you code should look like

Code:

---

public class dir
{
    public dir()
    {
        File folder = new File("c:/mydocument/");
        File [] listofFiles=folder.listFiles();

        //initialize the JList
        JList list = new JList();

        //set the listing of the directory as the data for the JList
        list.setListData(listofFiles);

        //add the list to whatever container you need
        ....
    }
}
