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.
/* 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);
string who=console.readLine("banana");
do{
if(who.equalsIgnoreCase(banana)||
who.equalsIgnoreCase(orange));
}
}while(who.equalsIgnoreCase(banana)

The semicolon shouldn't be within the evaluation of the condition. You forgot the opening curly brace for the if statement. But you actually don't need the if statement.
Within the do-while loop, put in the prompts when somebody answers "banana". Outside that loop, put in the prompts for the case when somebody answers "orange". The evaluation should be in within the braces of the while statement like you did.
I could write the correct code in here but I think one learns best when trying himself with some tips in mind :-). Try it, I am sure you will get it done yourself and if you still have problems just asked again.

19,750 PointsHey Andrew Wiley I think that should be a good start:
String who = ""; // has to be outside the loop
do {
// all the prompt for the case "banana"
console.printf("Knock Knock.\n");
who = console.readLine("Who's there? ");
console.printf("%s who?\n", who);
} while(who.equals("banana"));
// The rest should go here...
The handling for the case that one types in "orange" should then be outside the loop.
Can you do something with that?

19,750 PointsYou are welcome MUZ140118 MAKUYA I am glad that I could help you :-). Really trying yourself + asking for tips and hints is the best way to learn. If you only get the answer you will have more and more problems the more advance the exercises will get.

19,750 PointsHi,
I can see your mistakes but what are your exact problems? I only see you posting the exercises with your code but you don't state what your problem is. That way you won't learn anything good by just wanting to know the solutions.
