It is asking you to store the value the user inputs in the string variable.

I will give you a helping hand. 

String firstName = console.readLine();

In the code above I am storing whatever input the user gives in the String variable called firstName.

The readLine method reads input from the user.

Hello Peter,

To set a variable to the result of a function, you'll need to declare the type of the variable, the name and assign it to the output of a method. For example, for first name you would do this.

String firstName = console.readLine();

Then print the first name like this.

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

I hope this helps.

String firstName = console.readLine("Enter first name: ");
String lastName = console.readLine("Enter last name: ");
console.printf("First name: %s", firstName);
console.printf("Last name: %s", lastName);
