Listing only files in directory [closed]

Answer 1

Use a FileFilter instead, as it will give you access to the actual file, then include a check for File#isFile

File testDirectory = new File("C://rootDir//");
File[] files = testDirectory.listFiles(new FileFilter() {
    @Override
    public boolean accept(File pathname) {
        String name = pathname.getName().toLowerCase();
        return name.endsWith(".xml") && pathname.isFile();
    }
});

Answer 2

File testDirectory = new File("C://rootDir//");
File[] files = testDirectory.listFiles(new FilenameFilter()
 {

    @Override
    public boolean accept(File dir, String name) {
        return name.toLowerCase().endsWith(".xml");
    }});

What is the problem with above code. You can use this for listing files by excluding subfolders.

FileFilter also do's same thing but it will be used when file name is not sufficent to listing the files. i.e if you want list all hidden files or readonly file etc. you can use FilteFilter

Answer 3

Easier is to realise that the File object has an isDirectory method, which would seem as if it were written to answer this very question:

File testDirectory = new File("C://rootDir//");
File[] files = testDirectory.listFiles();
for (File file : files) {
    if ( (file.isDirectory() == false) && (file.getAbsolutePath().endsWith(".xml") ) {
       // do what you want
    }
}
