Delete Files with same Prefix String using Java

Question

I have around 500 text files inside a directory with a same prefix in their filename say dailyReport_.

With Java 8:

public static boolean deleteFilesForPathByPrefix(final String path, final String prefix) {
    boolean success = true;
    try (DirectoryStream newDirectoryStream = Files.newDirectoryStream(Paths.get(path), prefix + "*")) {
        for (final Path newDirectoryStreamItem : newDirectoryStream) {
            Files.delete(newDirectoryStreamItem);
        }
    } catch (final Exception e) {
        success = false;
        e.printStackTrace();
    }
    return success;
}

Simple version:

public static void deleteFilesForPathByPrefix(final Path path, final String prefix) {
    try (DirectoryStream newDirectoryStream = Files.newDirectoryStream(path, prefix + "*")) {
        for (final Path newDirectoryStreamItem : newDirectoryStream) {
            Files.delete(newDirectoryStreamItem);
        }
    } catch (final Exception e) { // empty
    }
}

Modify the Path/String argument as needed. You can even convert between File and Path. Path is preferred for Java >= 8.
