Using the console's printf method, display a message that says, "First name: ", followed by the first name that the user

Using the console's printf method, display a message that says, "First name: ", followed by the first name that the user has entered. Task 3:

// I have imported java.io.Console for you.  It is a variable called console.
String firstName=("first name");
String lastName=("last name");
console.readLine("%s", firstName);
console.readLine("%s", lastName);
console.printf("First name:%s", firstName);

This is my code but i don't get what i am doing wrong here. The code seems right to me? i get this error the whole time: Bummer! Did you forget to pass the firstName parameter to the printf function?

Nevermind here is the answer:

String firstName=("first name");
String lastName=("last name");
firstName = console.readLine("%s", firstName);
lastName  = console.readLine("%s", lastName);
console.printf("First name:%s", firstName);

HI eren, I'd be happy to help, but what are you stuck on? I'd probably encourage you to write your own question, if it is different than the above one.

Paul's original issue seems to have been that he had forgotten to assign the result of his console.readLine() to the firstName and lastName variables. Once he did that, the printf function could read the proper value in the variable.

If you've got more questions, feel free to ask.
