try-with-resources

Java 1.7 introduced try-with-resources statement: It uses objects that implement the java.lang.AutoCloseable interface and hence you don’t have to use finally block to close the resources.

try (RandomAccessFile in = new RandomAccessFile("file.ran", "r"))

        {           

            String s = in.readLine();

            return s;

        }

        catch (FileNotFoundException e)

        {

            System.out.println("File not found");

            System.out.println(e.toString());

            return null;           

        }

        catch (IOException e)

        {

            System.out.println("I/o error occurred");

            System.out.println(e.toString());

            return null;

        }
