Issue with readLine lesson

i understand the premise of the lesson and got the coding part down but on the Task part of the lesson when on stage 3 i must have First Name in it which i do it wont let me move on. Here is what my code is like: String firstName = console.readLine("What is your First name? "); String lastName = console.readLine("What is your last name? "); console.printf("Hello, my name is %s\n", firstName);

Did i miss something?

No, your other lines are wrong. readLine means that others can type stuff in after you say something. So:

String firstName = "Kai"; 
String firstName = "Kai"; console.readLine ("My first name is %s\n", firstName); // This isn't how you do it. Remember, this isn't printf. It's readLine.

// Try this:

String firstName  = console.readLine("First Name:  "); // This will say:  First Name: Then you can enter your first name.
// It will set what you entered to firstName.

Hope it helps!

Thanks, I realized after that I didn't actually understand the readLine haha.

i still dont get im not sure on what to type

This should work:

String firstName = console.readLine("First name:  ");
String lastName = console.readLine("Last name:  ");
console.printf("Hello, my name is %s", firstName);

Welcome to Treehouse!

You are doing great, you just need to change the formatting on your output to match what is asked in the challenge directions. In this case it is asking and looking for output to match "First name: " + the value of your first name utilizing the string formatter. If you make that change to your output your code should pass fine.

Post back if you are still stuck.

I'm having the same problem. I thought I would get it and it makes sense to me but it's not coming up correct. My whole thing looks like:

String firstName = "Kai"; console.readLine ("My first name is %s\n", firstName); String lastName = "Diaz"; console.readLine ("My last name is %s\n", lastName); //This is the code that I think should be right but apparently isn't... console.printf ("First name: %s\n", firstName);

//The hint reads "Did you forget to pass the firstName parameter to the printf function?" I guess I don't know how to pass the parameter on.
