print out punchline

I've tried to complete this a few different ways. This code is just my last attempt. I realize it's throwing task 1 off. I believe I am unclear on what the question wants.

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

console.printf("Orange\n");
who = console.readLine("------ who?\n");
console.printf("%s you glad I didn't say banana again?", who);

This is the correct code:

//Here is the prompting code
String who;
do {
console.printf("Knock Knock.\n");
who = console.readLine("Who's there?  ");
console.printf("%s who?\n", who);
} while (who.equals("banana"));
console.printf("%s who?", who);
console.printf("%s you glad I didn't say Banana again?", who);

You got the loop write but for the punchline you have to print "Orange who?" and "Orange you glad I didn't say banana again?" using the who variable. But I agree the code challenge is badly phrased.
