JList that contains the list of Files in a directory

Question

I created a JList that contains a list of files that are in a directory. Here is the JList.

JList MList;
String ListData[]
// Creat

I don't quite understand what you're doing - it looks like you want to filter the content of the JList to be only files with the .txt extension. In that case, you're probably looking to implement a FilenameFilter that will cause list() to return a list of file names in a String[] that only matches what you specified.

For example,

public String[] ReadDirectory() {
    String path = "C://Documents and Settings/myfileTxt";

    String files = null;
    File folder = new File(path);
    FilenameFilter txtFilter = new TextFileFilter();
    String[] listOfFiles = folder.listFiles(txtFilter);

    return listOfFiles;
}



public class TextFileFilter extends FilenameFilter
{
    public boolean accept(File dir, String name)
    {
        if(name != null && name.endsWith(".txt"))
        {
            return true;
        }

        return false;
    }
}
