}

c)

Scanner scanner = null;
try {
    scanner = new Scanner(new File("test.txt"));
    // some code
} catch (FileNotFoundException e) {
    e.printStackTrace();

    if (scanner != null) {
        scanner.close();
    }
}

d)

try {
    Reader reader = new FileReader("file.txt");
    try (reader) {

e)

try (Scanner scanner1 = new Scanner(new File("test1.txt"));
     Scanner scanner2 = new Scanner(new File("test2.txt"))) {
