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);

Hey!

Please could you copy and paste us your attempt so we can help correct that? You won't learn it anywhere near as well if I just straight up tell you the answer.

String who; // declare who string variable outside who block do { console.printf.(Knock Knock.\n"); String who = console.readLine("Who's there? "); console.printf("%s who?\n", who);
