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?
    ...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.

You need to wrap the code in a do...while block, and

check in the while condition to see if who is "banana" so that the loop continues.

You also need to move the String variable who outside of the loop

String who;    // move who variable outside of the loop
do {
    // Person A asks:
  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?  ");
  // Person B responds:
  console.printf("%s who?\n", who);
} while (who == "banana");   // continue the loop as long as who=='banana'
