java-7 - 尝试使用 Java 7 中的资源？

Question

在 Java 7 的新 Try-with-Resources 语法中，我是否需要担心资源的顺序？

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".
}

当且仅当使用正常的 try {create resources} finally {close resources} 语法时，顺序很重要。首先获取的资源将最后关闭。见 the technotes详情。
