For the first stage you can try the code below.

String who;
// Person A asks:
do { 
    console.printf("Knock Knock.\n");

// Person B asks and Person A's response is stored in the String who:
    who = console.readLine("Who's there?  ");
     console.printf("%s who?\n", who);
} while(who.equalsIgnoreCase("banana"));

After passing the first stage then for the second stage try the code below. if it helps please click best answer and if it doesnt ....give me a shout

if (who.equalsIgnoreCase("orange")){
console.printf(" %s you glad i did not ask for banana",who);
}

Hey there,

What this challenge is wanting you to wrap the entire joke in a do while loop.

The syntax is like below.

do {

// run through this code until the while condition is not met. 

} while (//condition that breaks loop);

So basically the first task is wanting you to put the whole condition in a loop and have it continue to go through the joke until who is not banana

We can do this by the follow

String who;
do {
console.printf("Knock Knock.\n");

// Person B asks and Person A's response is stored in the String who:
 who = console.readLine("Who's there?  ");
} while (who.equalsIgnoreCase("banana"));
// Person B responds:
console.printf("%s who?\n", who);

Notice we declare who outside of the loop, this is because during the second task of this assignment, we will need to use who again, and if it was only defined in the loop, we wouldn't have the scope to access it.

Thanks, let me know if this doesn't help.

Hey Kyle, I see you already got the answer, I just wanted to add a warning. The above code is having you change the already pre-written code and look through another if statement, that's not nessecary.

The only code that was needed to pass the second question is 

console.printf("%s you glad I didn't say banana?", who);

Causing the program to go through two if statements isn't necessary in this challenge.

Thanks, glad we got it worked out for you.
