Getting an error with boolean who.equals("banana");

Hello,

Can you please help me with this?

boolean who.equals("banana");

Not sure why am I getting an error message?

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.
*/
boolean who.equals("banana");
// ====BEGIN PROMPTING CODE====
do {

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

// Person B asks and Person A's response is stored in the String who:
String who = console.readLine("Who's there?  ");

// Person B responds:
console.printf("%s who?\n", who);
} while (who);
// ==== END PROMPTING CODE ====

//This looks like syntax for setting a boolean variable. 
boolean who.equals("banana");

// more correct: who.equals() will return a boolean value.
boolean checkIfStringIsBanana = who.equals("banana");

Try putting the check in the while ( ) instead.

Very good. Thanks.
