Question

Java:

Write a static method named longestName that reads a series of names typed by the user and prints the longest name (i.e., the name with the most characters). The method should accept a Scanner object, console and an integer, n as parameters. After prompting and reading in n names, the longest name should be printed as follows: its first letter should be capitalized and all subsequent letters lowercase, regardless of how the user entered the name. If there is a tie for the longest name (same number of characters), use the tied name that was typed earliest and print a message indicating there was a tie for the longest as indicated below. Note: You may assume that n is at least 1 and that each name is at least 1 character long, and that the user will type single-word names consisting of only letters. The following table shows two sample calls and their output.

Answer 1

import java.util.Scanner;

public class LongestNameFinder {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number of names: ");
       int n = sc.nextInt();
       System.out.println("Longest name: "+longestName(sc, n));
   }

   private static String longestName(Scanner sc, int n) {
       String name = "";
       String longN = "";
       sc.nextLine();
       System.out.println("Enter " + n + " names: ");
       //reading names from user
       for (int i = 0; i < n; i++) {
           name = sc.nextLine();
           //checking if current name is longest
           if (name.length() > longN.length())
               longN = name;
       }
       //converting first char to uppercase and rest all to lower cases
       return Character.toUpperCase(longN.charAt(0)) + longN.substring(1).toLowerCase();
   }

}
