Question

I’m creating an application that gets a list of .java and .class files from a chosen directory and places them in a JList. I am using Netbeans 7.1.2.

At the moment i have the files being retrieved and being placed into a List<File>. I have all the files in the list printing out but i cannot add them to the JList the is in my form.

this is how i am adding the files to the list

List<File> filesInDirectory = new ArrayList<>(); 

public List listFilesForFolder(final File folder) {

    for (final File fileEntry : folder.listFiles()) {
            if (fileEntry.isDirectory()) {
                listFilesForFolder(fileEntry);
            } else {
                        if(fileEntry.toString().toUpperCase().endsWith(".CLASS") || fileEntry.toString().toUpperCase().endsWith(".JAVA")){
                            filesInDirectory.add(fileEntry);
                            System.out.println(fileEntry.getName());
                        }
            }
        }

    return filesInDirectory;
}

Does anybody know how to do this?

Answer 1

DefaultListModel model = new DefaultListModel();
for(File f : yourFileList) {
    model.addElement(f);
}

yourList.setModel(model);
