Answer 1

import java.util.Scanner;

public class LongestRestaurantName {

    public static String readRestaurantName(Scanner in) {
        System.out.print("Enter restaurant name: ");
        return in.nextLine();
    }

    public static String findLongestRestaurant(String s1, String s2, String s3) {
        if (s1.length() >= s2.length() && s1.length() >= s3.length()) {
            return s1;
        } else if (s2.length() >= s1.length() && s2.length() >= s3.length()) {
            return s2;
        } else {
            return s3;
        }
    }

    public static String getLongestRestaurantName() {
        Scanner in = new Scanner(System.in);
        String restaurant1 = readRestaurantName(in);
        String restaurant2 = readRestaurantName(in);
        String restaurant3 = readRestaurantName(in);
        return findLongestRestaurant(restaurant1, restaurant2, restaurant3);
    }

    public static void printResult(String longestRestaurant) {
        System.out.println("Longest restaurant name is " + longestRestaurant);
    }

    public static void main(String[] args) {
        printResult(getLongestRestaurantName());
    }
}
