Can someone paste the answer for this challenge? I've been stuck on it for a while now and it's killing me


/*  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?
    ...as long as Person A has answered Banana the above repeats endlessly
    ...assuming the person answers Orange we'd see
    Person B:  Orange who?
    ...and then the punchline.
    Person A:  Orange you glad I didn't say Banana again?
    (It's a really bad joke that makes it sound like "Aren't you glad I didn't say Banana again?")

    Let's just assume the only two words passed in from the console from Person B are either banana or orange.


// Person A asks:
console.printf("Knock Knock.\n");

// Person B asks and Person A's response is stored in the String who:
String who = console.readLine("Who's there?  ");

// Person B responds:
console.printf("%s who?\n", who);

Hey there Dakota.

What they're asking you to is put the entire joke in a while loop while loop until who equals "banana" so until the user passes banana, they'll keep it repeating, I see you have if and else statements in your code, really all you need is to wrap the 3 lines in a do while loop, and make it run until the condition where who is equal to banana.

it would look something like below.

String who;

do {
    console.printf("Knock Knock.");
    who = console.readLine("Who's there?  ");
    console.printf("%s who?", who);
} while (who.equalsIgnoreCase("banana"));

Let me know if this doesnt help.

Thank you so much!
