Getting errors when compiling

This is my code:

import java.io.Console;

public class TreeStory {

    public static void main(String[] args) {
        Console console = System.console();
        /*  Some terms:
            noun - Person, place or thing
            verb - An action
            adjective - A description used to modify or describe a noun
            Enter your amazing code here!
        */
        // __Name__is__a__adjective__noun. They are always__adverb__verb.
        String ageAsString = console.readline("How old are you?  ");
        int age = Integer.parseInt(ageAsString);
        if (age < 13) {
          console.printf("Sorry you must be at least 13 to use this program. \n");
          System.exit(0);
        }

        String name = console.readLine("Enter a name:  ");
        String adjective = console.readLine("Enter an adjective:  ");
        String noun = console.readLine("Enter a noun:  ");
        if (noun.equalsIgnoreCase("dork")) {
          console.printf("That word is not allow. Exiting. \n\n");
          System.exit(0);
        }

        String adverb = console.readLine("Enter an adverb:  ");
        String verb = console.readLine("Enter a verb ending with -ing:  ");

        console.printf("My TreeStory:\n %s is a %s %s. They are always %s %s.\n",name, adjective, noun, adverb, verb);
    }

}

and this is my error when I run the code: treehouse:~/workspace$ javac TreeStory.java && java TreeStory
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
TreeStory.java:14: error: incompatible types: String cannot be converted to boolean
String ageAsString = console.readline("How old are you? ");
^
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output
1 error
Basically I have no idea how to fix this and why it occurs. Anybody can help ?

The error message is confusing, but the issue seems to be spelling "readline" (with lower-case "l") instead of "readLine" (with capital "L").
