need help understanding, converting toCharArray() to a string

Question

im fairly sure the mistake I am making within this code is short sighted. so this program starts by getting the first name and last name of the user and storing them as independent strings. the next part is for the program to manipulate that value into getting the first initial of the first name, which is where im having my problem (I have little experience with the CharArray function and have spent enough independent research time for me to opt to asking here lmao)

import java.util.Scanner; //Needed for the Scanner class

public class NumericTypes {
    public static void main (String [] args) {
        //TASK #2 Create a Scanner object here
        //Reading from system.in
        Scanner keyboard = new Scanner(System.in); 
        //prompt user for first name
        System.out.println("Enter your first name: "); 
        //scans the next input as a double
        String firstName = keyboard.nextLine(); 
        //prompt user for last name
        System.out.println("Enter your last name: "); 
        //scans the next input as a double
        String lastName = keyboard.nextLine(); 
        //concatenate the user's first and last names
        String fullName = (firstName + " " + lastName);
        //print out the user's full name
        System.out.println(fullName);
        //task 3 starts here
        //get first initial from variable 'fullName'
        String firstinitial = fullName.CharAt(0);
        System.out.println("the first initial is: " + firstinitial);
    }
}

my desired output is for the last set of lines to display the first initial of the first name (user input). any help would be greatly, greatly appreciated

and also wrap it with String.valueOf like this: String firstinitial = String.valueOf(fullName.charAt(0)); — Nick Ziebert, May 03 '17 at 04:18
first initial means you want the first character of the first name ? please give an example — robin, May 03 '17 at 04:30

This can be done in two ways -:

1.) Replace String firstinitial with char firstinitial

2.) Wrap fullName.charAt(0) with String.valueOf like this: String firstinitial = String.valueOf(fullName.charAt(0));

Both will work just fine.
