Is there an equivalent method to C's scanf in Java?

Question

Java has the notion of format strings, bearing a strong resemblance to format strings in other languages. It is used in JDK methods like String#format() for output conversio

Answer 1

Not an equivalent, but you can use a Scanner and a pattern to parse lines with three non-negative numbers separated by spaces, for example:

71 5796 2489
88 1136 5298
42 420 842

Here's the code using findAll:

new Scanner(System.in).findAll("(\\d+) (\\d+) (\\d+)")
        .forEach(result -> {
            int fst = Integer.parseInt(result.group(1));
            int snd = Integer.parseInt(result.group(2));
            int third = Integer.parseInt(result.group(3));
            int sum = fst + snd + third;
            System.out.printf("%d + %d + %d = %d", fst, snd, third, sum);
        });
