    Default Collecting user input error

    Ok first time poster here so please post any pointers on posting and any help in general. I'm very new to Java programming but I started this way with C++ and love it, I hope I can do the same with Java.

    So my problem is that I'm trying to create a program that will collect the first and last name of a user, convert to all lower case letters, and put it in a generic email format (firstname.lastname@waketech.edu).
    Troubles I'm having are that I can't get the user input to ask and collect the input. I don't know where to put the .toLowerCase().

    import java.util.Scanner;
    public class EmailGenerator
    {
     
    	/**
    	 * This method is to grab the users input and convert to all lower case letters
    	 * and put in an email address with given host. 
    	 *
    	 * @param args
    	 */
    	public static void main(String[] args)
    	{
    		// TODO Auto-generated method stub
    		Scanner firstName = new Scanner (System.in);
    		System.out.print("Enter your first name: ");
    		System.out.println(firstName);
     
    		Scanner lastName = new Scanner (System.in);
    		System.out.print("Enter your last name: ");
    		System.out.print(lastName);
     
    		System.out.print(firstName);
    		System.out.print(lastName);
    		System.out.println("@waketech.edu");
     
     
     
    	}
     
    }

    You can use a single instance of the Scanner class for reading all the user input. There does not need to be one for each thing that is read.

    Read the API doc for the Scanner class methods. There are examples of how to use them. Various methods will return the values that the user enters. The code has to save the returned values in variables.

    What did the code print out?

    where to put the .toLowerCase().
    Read the API doc for the String class to see how to use that method.
    If you don't understand my answer, don't ignore it, ask a question.

    I would use the code:
    Scanner input = new Scanner(System.in);
     
    String firstName;
    String secondName;
     
    System.out.println("First Name");
    firstName = input.next;
    System.out.println("Second Name");
    secondName = input.next;
     
    System.out.println(firstName+secondName+"@waketech.edu");
