Question

Write a method named generateHashtag that accepts a Scanner object as its parameter – your program should continuously read phrase (a line of input - can contain spaces) using the nextLine() method of the Scanner class until the String read in equals “done” (ignoring case).

For each phrase entered, your method should print a hashtag (#) followed by the phrase with spaces removed and all letters lowercase.

Answer 1

import java.util.Scanner;

public class HashTags {
        public static void main(String[] args) {
                Scanner sc = new Scanner(System.in);
                generateHashtag(sc);
        }
        public static void generateHashtag(Scanner sc) {
                String line=sc.nextLine();
                while(!line.equals("done")) {
                        line = "#"+line.replaceAll(" ", "").toLowerCase();
                        System.out.println(line);
                        line = sc.nextLine();
                }
                
        }
}
