Question

Can you assist me in understand and write the steps in this code?

Write a method named howMany that does not take in any arguments. Use the Scanner class to ask the user to enter a number between 1 and 5. Print One of the following based on their entry.

1    2 3 4 5   Anything Other Number   

“Lonely Num” “Company” "Crowd" "Fun" "Party"     "Only 1 to 5 Please"

Answer 1

import java.util.Scanner;

public class Example1 {
   public static void main(String[] args) {
       howMany();
   }

   private static void howMany() {
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number (1-5)");
       int i=sc.nextInt();
       //storing the messages in array so that we can print directly
       String arr[]= {"Lonely Num", "Company", "Crowd" ,"Fun", "Party"};
       //checking if it is between 1-5
       if(i<1 || i>5)
           System.out.println("Only 1 to 5 Please");
       else
           // printing i-1 as indexes starts from 0 to length-1 (0-4)
           System.out.println(arr[i-1]);
   }
}
