While loops

Question

Obviously I'm not getting how to do While loops in Java.

Do I at least have the syntax correct?

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====

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

// Person B asks and Person A's response is stored in the String who:
String who;
do {
 who = console.readLine("Who's there?  ");
} while (! who.equalsIgnoreCase("banana"));


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

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

Your syntax is close, you need to expand it to include all of the proper code to match the code prompt from the top of the challenge and it looks like you are trying to making it repeat as long as the input is not banana. I think the code wants the do...while loop to look something like:

do {
  //something
} while (who.equalsIgnoreCase("banana"));

Then once someone enters something other than "banana" you will print out the punch line.

Post back if you are still stuck.
