Java Java Basics Perfecting the Prototype Looping until the value passes

how did you tackle this one

We want to move that prompting code into a do while loop. Wrap the code into a do while code block and check in the while condition to see if who is "banana" so that the loop continues

/*  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;
do {
String who = console.readLine("Who's there?  ");

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

Having the same issue. Let me know if you figure it out. ^_^

Sorry for leaving that as an answer, rather than a comment. I'm still getting used to this. Jonathon posted an answer on my thread that might be of help to you:

*After where the comment reads "Begin prompting code", put do{

It will say "knock, knock", "who's there" prompt, use the prompt to say "(prompt) who." Then it needs to repeat. Before "end prompting code", put your }while(who=="banana")*

its ok i managed to do it.
