Reading a file with a Scanner

Reading a file line by line

public class Main {

    public static void main(String[] args) {
        try {
            Scanner scanner = new Scanner(new File("example.txt"));
            while(scanner.hasNextLine())
            {
                String line = scanner.nextLine();
                //do stuff
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

word by word

public class Main {

    public static void main(String[] args) {
        try {
            Scanner scanner = new Scanner(new File("example.txt"));
            while(scanner.hasNext())
            {
                String line = scanner.next();
                //do stuff
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

and you can also change the delimeter by using scanner.useDelimeter() method
