Java 7 ((hot)) Official
// Before Java 7 BufferedReader br = null; try br = new BufferedReader(new FileReader("file.txt")); br.readLine(); catch (IOException e) e.printStackTrace(); finally { if (br != null) try br.close(); catch (IOException e) {} }
While it didn’t radically change the syntax in the way Java 8 later would, Java 7 introduced essential refinements that streamlined developer workflows and laid the technical groundwork for the high-performance JVM (Java Virtual Machine) we use today. Key Features and Enhancements 1. Project Coin (Small Language Changes) java 7
Project Coin was a collection of "nice-to-have" features designed to reduce boilerplate code and make the language more expressive. // Before Java 7 BufferedReader br = null;
Path path = Paths.get("/home/user/data.txt"); // Create/delete Files.createDirectories(path.getParent()); Files.deleteIfExists(path); // Copy Files.copy(Paths.get("source.txt"), Paths.get("dest.txt"), StandardCopyOption.REPLACE_EXISTING); // Read all lines (small files) List<String> lines = Files.readAllLines(path, StandardCharsets.UTF_8); // Walk a directory try (DirectoryStream<Path> stream = Files.newDirectoryStream(Paths.get("/home"))) for (Path entry : stream) System.out.println(entry.getFileName()); Path path = Paths
You could now catch multiple exception types in a single block using the pipe symbol: catch (IOException | SQLException e) .
