How to correctly read from RandomAccessFile in Clojure?

I've been trying to develop a little library for reading MPQ files in Clojure, and I decided to use RandomAccessFile as MPQ is a binary format.

However, I'm having trouble with the method RandomAccessFile#read(), as I'm not really sure if I'm calling it correctly

here's the code:

(ns parser
  (:import (java.io RandomAccessFile)))


(with-open [file (RandomAccessFile. "r开发者_开发技巧eplay.SC2Replay" "r")]
  (let [x (byte-array 16)]
    (.read file [x 0 16])))

when I run the code, I get the

Exception in thread "main" java.lang.ClassCastException: clojure.lang.PersistentVector cannot be cast to [B (parser.clj:0)

exception. I also tried doing this for the temporary variable

(let [x []]

but it both yields the same exception. The same code in Java would be something like this

RandomAccessFile file = new RandomAccessFile("replay.SC2Replay", "r");
byte[] x;
file.read(x, 0, 16);

You're passing in a single vector as the argument, which it's trying to cast to a byte array so it can invoke the single argument read method that takes in a byte array. Just pass in the arguments as is.

(with-open [file (RandomAccessFile. "replay.SC2Replay" "r")]
  (let [x (byte-array 16)]
    (.read file x 0 16)))
