    String s1 = in.next();
    String s2 = in.next();
    String s3 = in.next();
    String s4 = in.next();

    if (s3.length() == s4.length()) {
        System.out.println("ARE Brothers");
    } else {

    }

Answer 1

Get the inputs, split by a space and get the second item in the resulting array to get the last name. Then compare the two using a ternary operator.

Scanner s = new Scanner(System.in);
String firstLastName = s.nextLine().split(" ")[1];
String secondLastName = s.nextLine().split(" ")[1];
String result = firstLastName.equals(secondLastName) ? "ARE Brothers" : "NOT";
System.out.println(result);
