Compliant Solution (Java 7, try-with-resources)
This compliant solution uses a try-with-resources statement (introduced in Java 7) to manage both br and bw.

try (BufferedReader br = new BufferedReader(new FileReader(inPath));
BufferedWriter bw = new BufferedWriter(new FileWriter(outPath));) {

} catch (IOException ex) {
System.err.println("thrown exception: " + ex.toString());
Throwable[] suppressed = ex.getSuppressed();
for (int i = 0; i < suppressed.length; i++) {
System.err.println("suppressed exception: " + suppressed[i].toString());
