Welcome to Treehouse!
It appears you are working on the Looping until value passes challenge in the Java Basics course, correct?
If so, and going strictly based on the code you posted, you are missing some line ending semi-colons and other important facets of the challenge.. Additionally, I think you are over-complicating what the task is asking. You can complete the challenge without an if
statement, as well as without the creation of a separate Boolean variable.
Something along the lines of:
String who;
do {
console.printf("Knock Knock.\n");
who = console.readLine("Who's there? ");
console.printf("%s who?\n", who);
} while(who.equalsIgnoreCase("banana"));
should suffice.
Do you follow along with what the above code is doing?
Happy coding,
Ken
