java error

im doing the java.io test, and it says ERROR: not a statement. What does that mean, and how do i fix it?

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

Let's first clean up your code to make it more readable. We do this by putting each statement on its own line. Remember, a statement ends with ;.

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

Now to the problems.

// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine();
String lastName = console.readLine();
printffirstName;  //<---- ';' tells the compiler we are done with this statement.
String firstName = console.readLine(); //<--- using 'String' re-declares the variable.

It appears you are trying to complete task 3.

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

We use that printf method like this:

console.printf("First name: %s", firstName);

I filled in the code for you, but %s is like a placeholder. We then tell the compiler what goes in that placeholder by putting it after the comma.

I am just going to assume the last String firstName was supposed to be a part of the printf.

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