Hi, it's okay to be wrong. Java is a difficult language and even I still have trouble with it some time. Take your time and good luck. Anyways here is the answer to your question:

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