FileLock to prevent deletion of a file but I can't open it

Question

I'm using a FileLock to prevent the deletion of a .zip file but I can't open it. So I'm trying to find something to block the file but be able to open it. There is my code :

File file = new File(myfile);

FileInputStream in = new FileInputStream(file);
FileChannel channel = new RandomAccessFile(file, "rw").getChannel();
FileLock lock = channel.lock();

try {
    lock = channel.tryLock();
} catch (OverlappingFileLockException e) {}

Thanks !

OH no ok Channels.newChannel(in) works perfectly
