definition of String who is outside the do block keep getting an error message

My definition of the "String Who;" is outside the do block ... Error message keeps asking me to move it outside the do block.

I kinda feel like this is the opening scene to Super Troopers - Where the kids are pulled over but the cop keeps asking them to pull over - and the drivers response is " I'm already pulled over, I can't pull over any further".

My String Who definition is already out side of the do block, I can't get it any more out side the do block.

What can I do ...


/*  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.

String Who;
do {
// 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);

What is the error message?

String Who;

Should be:

String who;

When I hit the check work button it comes back with "Bummer, remember to move the definition of String Who outside the do block ... Which I have done.

I actually get a error code when I use the "who" with a lower case .. but that is not what is stopping me from moving forward - It is telling me that I need to definition of string who outside the do block which it is.

Remove 'String' from the below line of code

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

I was stuck on this challenge and this post helped me as well. Thanks!
