Hints

charAt(0) gives the first character.

Character.toUpperCase(c) makes it a capital.

Start the print with a String so that + joins instead of adding char codes.

Solution explanation

Because a + "." involves a String, Java joins the characters as text. a + b on its own would add their code numbers!

Show solution

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String first = sc.nextLine();
        String last = sc.nextLine();
        char a = Character.toUpperCase(first.charAt(0));
        char b = Character.toUpperCase(last.charAt(0));
        System.out.println(a + "." + b + ".");
    }
}
