I have to print out the punch line after the while function and i have no idea how to go about doing this.

I have tried many different ways but it ends up just crashing the page and i have to restart.

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.
*/

// ====BEGIN PROMPTING CODE====

// Person A asks:
console.printf("Knock Knock.\n");
boolean isInvalidWord;
boolean validWord;

// Person B asks and Person A's response is stored in the String who:
String who; 
do 
{ 
  who = console.readLine("Who's there?  ");
  isInvalidWord = (who.equalsIgnoreCase("banana"));
  if(isInvalidWord) {
    console.printf("Knock Knock. \n"); }
} while(isInvalidWord);
{ 
  orange = (who.equalsIgnoreCase("orange")); 
 who = console.readline("Who's there?  ");
  if(orange) {
    console.printf("Orange you glad I didn't say Banana again?"); }
} while(orange);


// ==== END PROMPTING CODE ====

The loop needs to do something, while a specific condition exists. While the input is "banana" it should prompt fot the surname. Please notify me if this helps.

String who;

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

if(who.equals("orange"))
                   {console.print("orange you glad i'm not another banana?");
                   }

For the first stage u do this

String who;

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

for the second stage u do the following

if(who.equalsIgnoreCase("orange"))
                   {console.print("%s you glad i'm not another banana?", who);
                   }
