I am confused on how to enter the last part of the question. "followed by the first name that the user has entered.

// I have imported java.io.Console for you.  It is a variable called console.
String firstName = "Patrick";
console.readLine ("firstName");
String lastName = "Mitchell";
console.readLine ("lastName");

You have multiple errors on your code first you are not storing the input from the user because you are only receiving input when your write console.readLine() but you are not storing that value you must store the value in a variable like this -> String firstName = console.readLine("please enter your first name");

The second error is you are entering the parameters incorrectly, visit the code below I have provided to see the difference.

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