1. Add an import statement above the class declaration to make the Scanner class available to your program. 2. In the main method, create a Scanner object and connect it to the System. in object.
3. Prompt the user to enter his/her first name.
4. Read the name from the keyboard using the nextLine method, and store it into a variable called firstName (you will need to declare any variables you use).
5. Prompt the user to enter his/her last name.
6. Read the name from the keyboard and store it in a variable called lastName.
7. Concatenate the firstName and lastName with a space between them and store the result in a variable called fullName.
8. Print out the fullName.
9. Compile, debug, and run, using your name as test data.
10. Since we are adding on to the same program, each time we run the program we will get the output from the previous tasks before the output of the current task.

import java.util.Scanner;

public class Assignment{

public static void main(String [] args)

{

Scanner input = new Scanner(System.in);

String firstName, lastName;

System.out.print("Firstname: ");

firstName = input.nextLine();

System.out.print("Lastname: ");

lastName = input.nextLine();

String fullName = firstName +" "+lastName;

System.out.print(fullName);

}

}

Explanation:

I'll use the line numbers in the question to point at the corresponding instruction

import java.util.Scanner; -- The import statement (1)

public class Assignment{

public static void main(String [] args)

{

Scanner input = new Scanner(System.in); -- Scanner object (2)

String firstName, lastName; -- Variable declarations

System.out.print("Firstname: "); Prompt to enter first name (3)

firstName = input.nextLine(); --- User input for firstName (4)

System.out.print("Lastname: "); Prompt to enter first name (5)

lastName = input.nextLine(); --- User input for lastName (6)

String fullName = firstName +" "+lastName; --- concatenating both user inputs (7)

System.out.print(fullName); --- Print out fullName (8)

}

}
