Stage 3 Challenge 2 printing the punch line

So I'm trying to print the punch line here, but I don't know what I'm missing. I executed the loop and now if everything checks it should print the variable which is who. But I am getting an error.

KnockKnock.java 
/*  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?
*/

//Here is the prompting code
String who;

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

Hello Henry so If you remember in the last video we learned about booleans. this challenge has 2 task. first we need to create the do while loop , than the punchLine. so here is what it should look like this is the first part.

String who;

boolean answer;

do{

console.printf("Knock Knock.\n");

who = console.readLine("Who's there? ");

answer = (who.equalsIgnoreCase("banana"));

if (answer){

  console.printf("%s who?\n", who);

}

  }

  while(answer);

than if the answer is "Orange" than we can print out the punchLine.

        console.printf("%s you glad I didn't say Banana again?", who);

Hope this helps!!!
