Scanner scan = new Scanner(System.in); // Create a Scanner Object to work on first
System.out.println("Enter xyz") // Ask user a question
String answer; // Initialize the string variable to record answer, note below

You can use one of many ways to assign data to the string depending on how much you want to copy. For example

String answer = scan.nextLine(); // Capture text separated by the Enter key
int answer = scan.nextInt(); // Capture integer to variable
