This is because you aren't printing out what the challenge is telling you to print out. The instructions say:

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

and

Using the console's printf method, display a message that says, "Last name: " followed by the last name that the user has entered.

Yet you are entering other text, linebreaks, and didn't even use the last name in the final challenge. So in order to pass, you'll need to enter, exactly what the instructors tell you to. Otherwise the tests will fail, even if the code itself technically prints the variable.

In otherwords to solve this, you need to do the following:

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