A better way of IO streams exception handling?

I think there is a better way how to handle exceptions for IO streams. Or did I miss anything? I found these 3 ways how to properly handle IO streams: http://javarevisited.blogspot.cz/2014/10/right-way-to-close-inputstream-file-resource-in-java.html

I think try with resources is the best way to handle the case when you have to close an IO stream, provided that you have Java 7 installed

try (FileInputStream fis = new FileInputStream("../input/fxrates.txt"); 
    FileOutputStream fos = new FileOutputStream("../output/fxrates.tx")) { 
    // code for reading contents ..... 
}  catch (IOException ioex) { 
    System.out.println("Failed to copy files : " + ioex.getMessage());

And this code will work with any resource that implements Autocloseable, not just streams :D
