Java Program to Display Full Name of user

Write a Java program to accept first name, middle name and surname in three different strings and then concatenate the three strings to make full name.

Source Code

import java.util.Scanner;

public class FullNameString {

	public static void main(String[] args) {

		Scanner input = new Scanner(System.in);
		
		System.out.print("Enter first name :: ");
		String firstName = input.nextLine();
		
		System.out.print("Enter middle name :: ");
		String middleName = input.nextLine();
		
		System.out.print("Enter surname :: ");
		String lastName = input.nextLine();
		
		// Here StringBuffer is used to combine 3 strings into single
		StringBuffer fullName = new StringBuffer();
		fullName.append(firstName);
		fullName.append(" ");   // For space between names
		fullName.append(middleName);
		fullName.append(" ");   // For space between names
		fullName.append(lastName);
		System.out.println("Hello, " + fullName);
	}
}
