java - I must process the sentence by calling the method rather than processing the string directly in my main method! PS i need to use void method

Question

import java.util.Scanner;
public class PrintVertical
{

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Please enter a sentence: ");
        String input = in.nextLine();

        int i =0;
        System.out.println("Your sentence printed vertically is:");
        for(i = 0; i < input.length(); i++) {
            char letter = input.charAt(i);
 
            System.out.println(letter);
        }
    }
}

Answer 1

• Write a new method besides the main-method in your class and mark it with the keyword static.(Class Methods)
• Give it a String as Parameter. To call it with your user input.

The Static Function:

  public static void doVertic(String inp){   
    int i =0;
    System.out.println("Your sentence printed vertically is:");
    for(i = 0; i < input.length(); i++) {
        char letter = input.charAt(i);

        System.out.println(letter);
    }
}

• Then call it with your scanned input inside the main method

Call in Main Method:

public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    System.out.print("Please enter a sentence: ");
    String input = in.nextLine();
    <Classname>.doVertic(input);
}

Note: The <Classname> have to be your Classname
