I have one scenario where I am trying to implement with the Java 7 'try with resource' feature.
My finally block contains an object of BufferedWriter
and File
, which I want to close using 'try with resource' feature, instead of closing it by calling close method explicitly.
But I checked on net and saw that the File
class does not implement the AutoCloseable
interface, but BufferedWriter
does. So how can I manage this scenario to implement 'try with resource' feature?
try (BufferedWriter br = new BufferedWriter(new FileWriter(path)))
Use this simply, br will be closed automatically. Eg. http://www.roseindia.net/java/beginners/java-write-to-file.shtml
You don't need to close a File
because it's a pure Java object. It basically just holds the name of the file, nothing else (i.e. it does not require any OS resources to construct).
You only need to close your BufferedWriter
and that is correctly AutocCloseable
.
