method printf doesnt not exist in your code so you have to call static method from Libery System by typing : System.out.printf() or Console ( console no works in real IDE ) better use System.out :)

out ( Output) in ( input )

// 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( "firstName: %s",nikhil);

even though it is not compiling this is my code
