The following piece of code describes how to silently and properly close a stream resource in Java:
File f = new File("SomeFile.txt");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(f);<
// Do something...
} catch (FileNotFoundException ex) {
// Display error message
} finally {
// Closing resource
if ( fos != null ) {
try {
fos.close();
} catch (IOException ex) {
// Silently ignore it
}
}
}
Yet, the amount of code required to close each stream in
finally is nothing but clutter which does not help with readability too. Fortunately, the Apache Commons library offers a
tool solving this issue:
} finally {
IOUtils.closeQuietly(out);
}
