java - Problems with generating another "Joke" Statement -

currently, creating simple program tells jokes users.

bot: how can 4 suits dollar? type reveal view answer
you: reveal
bot: buy deck of cards. giggle giggle
bot: wish continue? yes or no?
you: yes
bot: call boomerang won't come back? type reveal view answer

that intended script. however, faced problem:

bot: wish continue? yes or no?
you: yes
bot: wrong >:d

the bot print out "wrong" instead of generating joke. here code:

public class newclass {      public static void main(string[] args) {         int randomnumber;         string userinput;          string[] jokesanswer = {"snowballs! haha ", "a stick!!! :d", "a pork chop.", "a piano! hehe ", "a dead centipede!! xd", "at crystal ball. *chuckle chuckle*",             "a conversation. teehee", "buy deck of cards. *giggle giggle*"};         string[] jokes = {"what difference between snowman , snowwoman?", "what call boomerang won't come back?",             "what call pig karate?", "what has lot of keys can not open doors?", "what lies on back, 1 hundred feet in air?",             "where fortune tellers dance?", "what can hold without ever touching it?", "how can 4 suits dollar?"};          randomnumber = (int) (math.random() * jokes.length);         system.out.println("bot: " + jokes[randomnumber] + " type reveal view answer");         scanner input = new scanner(system.in);         {             system.out.print("you: ");             userinput = input.nextline();             userinput = userinput.tolowercase();             if (userinput.equals("reveal")) {                 system.out.println("bot: " + jokesanswer[randomnumber] + "\nbot: want hear joke? :d yes or no?");             } else {                 system.out.println("bot: wrong! >:d");             }         } while (!userinput.equals("no"));      } 

your logic little bit broken. need tell joke within do-while loop, else you'll ever tell once. need able handle situation repeatedly type other 'reveal', added loop case. it's while-loop opposed do-while because not need guaranteed happen @ all.

scanner input = new scanner(system.in);  {     randomnumber = (int) (math.random() * jokes.length);     system.out.println("bot: " + jokes[randomnumber] + " type reveal view answer");      system.out.print("you: ");     userinput = input.nextline();     userinput = userinput.tolowercase();      while (!userinput.equals("reveal"))     {         system.out.println("bot: wrong! >:d");          system.out.print("you: ");         userinput = input.nextline();         userinput = userinput.tolowercase();     }      system.out.println("bot: " + jokesanswer[randomnumber] + "\nbot: want hear joke? :d yes or no?");      system.out.print("you: ");     userinput = input.nextline();     userinput = userinput.tolowercase();  } while (!userinput.equals("no")); 

i move user input statements own function avoid code duplication.
