How to find files that match a wildcard string in Java?

Question

This should be really simple. If I have a String like this:

../Test?/sample*.txt

then what is a generally-accepted way to get a list of fil

Answer 1

Here are examples of listing files by pattern powered by Java 7 nio globbing and Java 8 lambdas:

    try (DirectoryStream dirStream = Files.newDirectoryStream(
            Paths.get(".."), "Test?/sample*.txt")) {
        dirStream.forEach(path -> System.out.println(path));
    }

or

    PathMatcher pathMatcher = FileSystems.getDefault()
        .getPathMatcher("regex:Test./sample\\w+\\.txt");
    try (DirectoryStream dirStream = Files.newDirectoryStream(
            new File("..").toPath(), pathMatcher::matches)) {
        dirStream.forEach(path -> System.out.println(path));
    }
