You are very close.
The message that is printed to the console is the format string, it is the first parameter that is passed to printf. That string needs to output "First Name: Kunal". I think you might have gotten confused because you did not realize that "First Name:" needed to be part of the format string.
The variable, firstName, is the second parameter passed to printf, and it will replace the format specifier %s in the format string.
Notice how the 2 parameters passed to printf in parenthesis, the format string and the variable, are separated by commas.
Notice how the format string is surrounded by quotes but the variable, firstName is not.
console.printf("First name: %s\n", firstName);

Happy Coding! Heidi

One more thing I noticed.
When you are calling the readLine method, the text in the quotations should be the question you are asking the user. You put your name in the quotations, but it is the user's answer that will get assigned to the string variable when they enter something into the prompt.
Hope that helps clarify. Heidi
