How to search for a subdirectory from a parent directory? [closed]

Answer 1

Use Files.walkFileTree, it will recursively show your sub-directory corresponding to your parent directory.

public static void main(String[] args) throws IOException {
    Path startingDir = Paths
            .get("C:\\projects\\workspace\testing");
    Files.walkFileTree(startingDir, new FindJavaVisitor());
}

private static class FindJavaVisitor extends SimpleFileVisitor {
     @Override
    public FileVisitResult preVisitDirectory(Path dir, 
                          BasicFileAttributes attrs) throws IOException {
    if(dir.getFileName().toAbsolutePath().toString().contains("z1")){
        System.out.println("z1 is found at"+ dir.getFileName().toAbsolutePath());
    }
      return FileVisitResult.CONTINUE;
    }
}
