public class ScannerVsBufferedReader{

    public static void main(String[] args) {

        // Using Scanner to read user input
        Scanner scnr = new Scanner(System.in);
        System.out.println("=======================================");
        System.out.println("You can use Scanner to read user input");
        System.out.println("=======================================");
        System.out.println("Please enter a String");
        String name = scnr.nextLine();
        System.out.println("You have entered " + name);
        System.out.println("Please enter an integer");
        int age = scnr.nextInt();
        System.out.println("You have entered " + age);

        scnr.close();

        // Using BufferedReader to read a file
        System.out.println("=======================================");
        System.out.println("You can use BufferedReader to read a file");
        System.out.println("=======================================");
        FileReader fileReader;
        try {
            fileReader = new FileReader("abc.txt");
            BufferedReader buffReader = new BufferedReader(fileReader);

            System.out.println("File contains following lines");
            String line = buffReader.readLine();

            while (line != null) {
                System.out.println(line);
                line = buffReader.readLine();
            }

            buffReader.close();
            fileReader.close();

        } catch (IOException e) {
            e.printStackTrace();
