stage 3, task 1 of 2

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);

Hi,

can you tell us what your problem is? What is your attempt? We will gladly help.

I could just write you the answer but you really won't learn anything like that.

Try this:

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

String who; 

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.equalsIgnoreCase("banana"));

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

console.printf("%s you glad i didn't say banana again", who);
