Question

In the new Try-with-Resources syntax in Java 7 do I need to worry about the order of the resources?

try (InputStream in = loadInput(...); // <--- can these be in any order?
     OutputStream out = createOutput(...) ){
    copy(in, out);
}
catch (Exception e) {
    // Problem reading and writing streams.
    // Or problem opening one of them.
    // If compound error closing streams occurs, it will be recorded on this exception 
    // as a "suppressedException".
} 

Answer 1

Order matters if and only if it would matter when using the normal try {create resources} finally {close resources} syntax. Resources which were acquired first will be closed last. See the technotes for details.
