Java Java Basics Perfecting the Prototype Looping until the value passes

stage 3 challenge 1

Read the comments and code below. We want to move that prompting code into a do while loop. Wrap the code into a do while and check in the condition to see if who equals "banana" so the loop continues. Remember to move your who declaration outside the do block.

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

You just posted the question and only changed a little bit. I would advise to not open another thread if you already opened one for same question (You already opened at least 6 threads today with the title stage 3 challenge 1). Otherwise others don't know what already has been answered and you may get same answers for the same topic.

I wouldn't mind but you always only copy/paste the exercise question with your code and that way you really won't learn anything.

l tried it did not work out

In your second last thread I answered you, that you should put the prompts within the do-while loop and some other things :-). But you haven't done that yet.

If you have problems with this exercise I think it's because others already answered the exercises before for you, so now you don't know what your current problem is and will be for the future exercises. Therefore it would be best imo to do the last exercises again yourself so you know what you may have missed.

This is just my opinion and no offense though :-).

thanks .l made it

Do you have any questions about the do-while blocks or things with the challenge that you got stuck on?
