Stage 3 Perfecting the Prototype Task 2/2 - printing the punch line.

Hey guys, i already searched the forum and found an answer in this link : https://teamtreehouse.com/forum/stage-3-challenge-2-printing-the-punch-line , but when i try it out.. its not working could you have a look and leave me a comment? thanks!

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?
    ...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.
*/

// ====BEGIN PROMPTING CODE====

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);

// ==== END PROMPTING CODE ====

You need to comment out the line just after the while loop, and add a curly bracket to close the while loop. You can also delete the if statement in the loop, though it passes with it too:

String who;
boolean answer;
do
{
  console.printf("Knock Knock.\n");
  who = console.readLine("Who's there? ");
  answer = (who.equalsIgnoreCase("banana"));
  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);
