IOUtils.closeQuitely for FileChannel

Question

I wanted to know the Apache library method IOUtils.closeQuitely does well with FileChannel. I see it takes Closeable as argument and FileChannel does implement it up in hierarachy. But can we face any issue down the line. Any experience one can share please.

Answer 1

I think it's OK if we use it as IOUtils.closeQuietly API suggests, ie double-close

    FileChannel ch = null;
    try {
        ch = new FileInputStream("foo.txt").getChannel();
        // process
        ch.close();
    } catch (Exception e) {
        // error handling
    } finally {
        IOUtils.closeQuietly(ch);
    }

But try-with-resources if Java 7 is available is a much cleaner way.
