Java io ugly try-finally block

Question

Is there a not so ugly way of treat the close() exception to close both streams then:

    InputStream in = new FileInputStream(inputFileName);
          


        

Answer 1

You could implement a utility method:

public final class IOUtil {
  private IOUtil() {}

  public static void closeQuietly(Closeable... closeables) {
    for (Closeable c : closeables) {
        if (c != null) try {
          c.close();
        } catch(Exception ex) {}
    }
  }
}

Then your code would be reduced to:

try {
  copy(in, out);
} finally {
  IOUtil.closeQuietly(in, out);
}

I imagine there'll be a method like this in a 3rd party open-source library. However, my preference is to avoid unnecessary library dependencies unless I'm using a large portion of its functionality. Hence I tend to implement simple utility methods like this myself.
