    public static String ufnFullName (String Fname, String Lname) {

    String FullName = Fname+" "+Lname;

    return FullName;

    }

    Explanation:

    Using Java programming language, the function is created to accept two String parameters (Fname and Lname)

    These are concatenated into a new String FullName and returned by the function

    See below a complete code that prompts users to enter value for first and last names then calls this method to display the full name

    import java. util. Scanner;

    public class FullName {

    public static void main (String[] args) {

    System. out. println ("Enter First Name");

    Scanner in = new Scanner (System. in);

    String Fname = in. next ();

    System. out. println ("Enter Last Name");

    String Lname = in. next ();

    System. out. println ("Your Full Name is "+ufnFullName (Fname, Lname));

    }

    public static String ufnFullName (String Fname, String Lname) {

    String FullName = Fname+" "+Lname;

    return FullName;

    }

    }
