I encountered end of file error. I checked to make sure I close all my curly braces

public static void main(String[] args) {
    Console console = System.console();
     String ageAsString = console.readLine("How old are you?  ");
    int age = Integer.parseInt(ageAsString);
    if (age < 13) 
    {
        //insert exit code
        console.printf("Sorry you must be at least 13 to use this program.\n");
        System.exit(0);
    }
    String name = console.readLine("Enter your name:  ");
    String adjective = console.readLine("Enter an adjective: ");
    String noun;
    boolean isInvalidWord;
    do 
        {
        noun = console.readLine("Enter a noun:  ");
        isInvalidWord = (noun.equalsIgnoreCase("dork") ||                                                   noun.equalsIgnoreCase("jerk"));
        if (isInvalidWord) {
            console.printf("That language is not allowed. Try again \n\n");
        } while(isInvalidWord);
    String adverb = console.readLine("Enter a adverb:  ");
    String verb = console.readLine("Enter a verb:  ");
    console.printf("Your TreeStory:\n_______________________\n ");
    console.printf("%s is an %s %s.", name, adjective, noun);
    console.printf("They are always %s %s.\n", adverb, verb);
    }
}
