Using the console's printf method, display a message that says, "Last name: " Java basics challenge 4/4

i cannot figure out what is wrong with this code.

IO.java 
// I have imported java.io.Console for you.  It is a variable called console.
String firstName=console.readLine("What is your first name?  ");
console.printf("my name is %s\n",firstName);
String lastName = console.readLine("What is your last name?  ");
console.printf("first name: %s\n",firstName);
console.printf("last name: %s\n",lastName);

Hey Matthew,

Although you have no syntax errors, your answer really doesn't satisfy what the challenge is specifically asking for.

  • First, it's a real good practice to keep you code in the order of what the Tasks are asking (unless specifically told otherwise. Eg. Task One: wants first name variable and Task Two: wants last name variable, so the last name one should be directly under the first name one.

  • Second, Challenge are very picky and very strict in what they ask for and what they check for. These tasks want your to print the string "First Name: " with both a capital "F" and and "Capital "N"... same thing with "Last Name: " (Capital "L" and Capital "N"

  • Third, none of the 4 tasks asked for the line "My name is....", so that needs to be deleted.

Below is the corrected code for your review. Please have a look over and make sure it makes sense.

// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine("What is your first name?  ");
String lastName = console.readLine("What is your last name?  ");

console.printf("First Name: %s\n", firstName);
console.printf("Last Name: %s\n", lastName);

Keep Coding! :) :dizzy:
