       String FullName = Fname+" "+Lname;

       return  FullName;

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

<em>import java.util.Scanner;</em>

<em>public class FullName {</em>

<em>    public static void main(String[] args) {</em>

<em>        System.out.println("Enter First Name");</em>

<em>        Scanner in = new Scanner(System.in);</em>

<em>        String Fname = in.next();</em>

<em>        System.out.println("Enter Last Name");</em>

<em>        String Lname = in.next();</em>

<em />

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

<em>    }</em>

<em>    public static String ufnFullName(String Fname, String Lname){</em>

<em>        String FullName = Fname+" "+Lname;</em>

<em>        return  FullName;</em>

<em>    }</em>

<em>}</em>
