Query of files from folder "files" in project

Question

I have a folder "files" in my project. I want to create a query of all files in it. 1. How to open that folder without specifying the full path? 2. How to put all files from my folder to this query?

ArrayDeque<File> files = new ArrayDeque<File>();

I wrote some code. But program give me the name of folder instead the name of files in it. So my program don't find a folder in my project-folder. How I can get my folder "folder1" without all path? It's my code

public static void main(String args[])
{
    File file = new File("<folder1>");
    ArrayDeque<File> queue = new ArrayDeque<File>();
    filesQueue(file, queue);
    System.out.print(queue.getFirst());
}

public static ArrayDeque<File> filesQueue(File f,  ArrayDeque<File> queue) {
        if (f.isDirectory()) {
            for (File file : f.listFiles()) {
                filesQueue(file, queue);
            }
        } else {
            queue.addLast(f);
        }

    return queue;
}

File file=new File("<folder-name>");
ArrayDeque<File> filesQueue=listFiles(file);

static ArrayDeque<File> fileList=new ArrayDeque<File>();
public ArrayDeque<File> listFiles(File folder) {

    for (File f : folder.listFiles()) {
        if (f.isDirectory()) {
            listFiles(f);
        } else {
           fileList.add(f);
        }
    }
return fileList;
}

Your recursion won't add to the same `fileList` as the current invocation. – Klitos Kyriacou Feb 26 '16 at 12:52
