It says, "Add a variable to store a user’s first name using console.readLine. Make sure the variable is the camel cased representation of "first name"

// I have imported java.io.Console for you.  It is a variable called console.

Welcome to Treehouse!

If we break this task down into little bits, we have:

1) We need a camel case representation for a String variable named "first name," String firstName

2) We need to get input from a user via the console.readLine() function and pass it to our variable. Let's be nice and add in some prompting text.

String firstName = console.readLine("Please enter your first name: ");

That will print out Please enter your first name: to the console and accept a string value in as a response.

Please post back if you are still stuck.

Happy coding,


CamelCase are words written like that -> "camelCase" or "CamelCase". In Programming Languages it's more like "camelCase " for variables - the first letter is always a small one.

to add a value like your first name to a variable via the console.readLine method you have to actually first declare the variable:

"private String theVariable;"

after that you can define or specify it with a certain value. Actually you're putting a value into it by a user prompt with the console.readLine().

if you don't have a clue yet: "private String firstName = console.readLine("Please enter your first name: ");" is what you should write to solve the challenge.

Be sure to review the video once or twice before posting a question. I do this aswell because I might missed out a particular information aswell.
