Listing only files in directory [closed]

Answer 1

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
    }
}
