I don't understand what the question is asking. Are they asking me to complete the full knock knock joke?

/*  So the age old knock knock joke goes like this:
        Person A:  Knock Knock.
        Person B:  Who's there?
        Person A:  Banana
        Person B:  Banana who?
        ...This repeats until Person A answers Orange
        Person A:  Orange
        Person B:  Orange who?
        Person A:  Orange you glad I didn't say Banana again?
*/
String who;
String who2;
boolean correctWord;
boolean correctWord2;
//Here is the prompting code
do {
  console.printf("Knock Knock.\n");
  who = console.readLine("Who's there?  ");
  correctWord = who.equalsIgnoreCase("Banana");
} while(correctWord);
console.printf("%s who?\n", who);

do {
  who2 = console.readLine("%s who?\n", who);
  correctWord2 = who2.equalsIgnoreCase("Orange");
} while(correctWord2);
console.printf("%s who?\n", who2);
console.printf("%s you glad I didn't say Banana again?". who2, who);
