750 PointsI am having difficulties getting past the Java Basics knockknock.java challenge. Keeps telling me to try again.
My code does not have compiler errors - but the code check fails and I am forced to try again. I can run the code in my workspace. What do I need to do to get past this step?
import java.io.Console;
public class Joke {
public static void main(String[] args) {
Console console = System.console();
String who;
boolean isBananaWho;
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\n\n", who);
isBananaWho = (who.equalsIgnoreCase("banana"));
}
while (isBananaWho);
if
(who.equalsIgnoreCase("orange"));
console.printf("%s you glad I didn't say Banana again?\n", who);
System.exit(0);
} }
/* 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====
String who;
boolean isBananaWho;
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\n\n", who);
isBananaWho = (who.equalsIgnoreCase("banana"));
}
while (isBananaWho);
if
(who.equalsIgnoreCase("orange"));
console.printf("Orange you glad I didn't say Banana again?\n");
System.exit(0);
// ==== END PROMPTING CODE ====

750 PointsYep - the syntax was not quite right. Changed my IF statement to look like this:
if ( who.equalsIgnoreCase("orange") ) { console.printf("%s you glad I didn't say Banana again?\n", who); System.exit(0);
...and runs fine now. Thanks for your speedy help. i have now completed the Java basics and hope to start the Java Objects tutorial tomorrow.
Regards,
Richard

Treehouse TeacherAre you missing a closing curly brace for your if? If not the System.exit might be messing up the runner.
Your logic looks great!
