error detection

String noun;
     do{
       noun= console.readLine("enter a noun:  ");
        if (noun.equalsIgnoreCase("dork") || noun.equalsIgnoreCase("jerk"));
       {
         console.printf("That language is not allowed please try again later.. \n");
      }
     }  

      while (noun.equalsIgnoreCase("dork")|| noun.equalsIgnoreCase("jerk"));

      String name= console.readLine("enter your name  ");
      String adjective= console.readLine("enter an adjective  ");
      noun= console.readLine("enter a noun  ");
      console.printf(" %s is a very %s girl \n , she lives in %s \n",name, adjective,noun);

the main problem is when i am giving any name apart from dork and jerk then too it is printing( the language is not allowed line ) which should not get print .

Hi there,

Which task/course is this in? Does it require a do|while or could you use a while loop?

Something like: Enter a noun - while noun equals(list of illegal words), keep looping and warning - else carry on through the code.

I've not got an IDE here, so this is just for an example - it'll be unlikely to work! 

String noun = console.readLine("Enter a noun: ");

while (noun.equalsIgnoreCase("dork")|| noun.equalsIgnoreCase("jerk")) {
  noun = console.readLine("That language is not allowed. Try again: ");
}

// rest of code here : no more noun code, though!!
String name= console.readLine("Enter your name:  ");
String adjective= console.readLine("Enter an adjective:  ");

Make sense?

Steve.

Meenakshi;

It looks like you have some extra semi-colons that are posing issues. The syntax for an if statement is:

if (someConditionToCheck.equals(somethingToCheckAgainst)) {
       // do something magical
}

Notice that at the end of the conditional checking that there is not a semi-colon, like you have in your code.

Post back if you are still stuck.

Happy coding,
Ken
