  • You can write your own `FileFilter` - in particular, you'll place your implementation when you @Override `accept()` – sleepToken Jan 21 '20 at 16:36

Something like this should work:

try (Stream<Path> paths = Files.walk(Paths.get("/home/you/Desktop"))) {
    paths
        .filter(Files::isRegularFile)
        // You can also use Apache StringUtils.containsIgnoreCase()
        .filter(path -> path.getFileName().toString().toLowerCase().contains(word.toLowerCase()))
        .forEach(System.out::println);
}
