There's 4 parts to this question. First is Declare a variable that is named the camel-cased version of "first name". Store the user's first name into this new variable using console.readLine. For that you need to create a String called firstName and ask for user input, as it says. That line looks like:
String firstName = console.readLine("Enter your first name: ");
Next, the question is Declare another variable, naming this one the camel-cased version of "last name". Use console.readLine to store the user's last name into this new variable. THat's pretty much the same as above:
String firstName = console.readLine("Enter your first name: ");
String lastName = console.readLine("Enter your last name: ");
Next you want to output the first name Using the console's printf method, display a message that says, "First name: ", followed by the first name that the user has entered. That's using string interpolation to dd the value held in firstName where the %s is in the output string. Like this:
String firstName = console.readLine("Enter your first name: ");
String lastName = console.readLine("Enter your last name: ");
console.printf("First name: %s", firstName);
And the last tak is similar to the third Using the console's printf method, display a message that says, "Last name: " followed by the last name that the user has entered.
String firstName = console.readLine("Enter your first name: ");
String lastName = console.readLine("Enter your last name: ");
console.printf("First name: %s", firstName);
console.printf("Last name: %s", lastName);
I hope that helps you.
Steve.

console.printf = method? (or function) First name = variable? firstName = parameter?
console.printf("First name: %s", firstName); console.printf("Last name: %s", lastName);

In the first line console is an instance (object) of the Console class. Then, printf is a method (or function) of the Console class instances. A method and function are interchangeable names for the same thing.
Next we are creating a variable of type String called firstName. It could be called an instance of the String class holding the value you assign to it, but let's not. The variable firstName holds a string like "Steve".
In the last line, you are using the string formatting capability of printf. This allows you to insert the value of a variable into a string that you define. You are passing two things into the printf method/function. First is the string you want to have a value inserted into, "First name: %s", then the variable whose value you want to insert at the %s position, firstName. You can call both those things parameters when used in this way. A value passed into a method is a parameter. So, on one line, firstName is a string variable, next you are using the same string variable as a parameter of the printf method.
Let me know if that doesn't make sense and I'll have a better try!
