Java Java Basics Perfecting the Prototype Parsing Integers

My workspace never displays, "How old are you ?". I get several errors although I typed everything exactly the same as C

My workspace never displays, "How old are you ?". I get several errors although I typed everything exactly the same as Craig. How can I reset my workspace back to the default before what I recently saved? I may have deleted important code.

Thank you. You are indeed missing a closing bracket.

You should have:

  • a closing bracket for the if block
  • a closing bracket for the main method
  • a closing bracket for the class

You were actually missing 2 previously. My bad, I only saw 1 missing. I edited my previous answer. Just add a closing bracket and you will be fine :)

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) {
        //Insert exit code
        console.printf("Sorry you must be at least 13 to use this program.\n");
        System.exit(0);
      }    // <- closing bracket for the if block
    }      // <- closing bracket for the main method
}          // <- closing bracket for the class

screen shot your code please

Hi Monica. You have 2 options:

  • Go to Workspaces on the right of the Treehouse top menu bar up there ^ (next to your points) and delete the workspace from the list. Then re-create a brand new one from the lesson.
  • Post your code here so we can help you find where the error is.

Hope that helps :)

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) {
    //Insert exit code
    console.printf("Sorry you must be at least 13 to use this program.\n");
    System.exit(0);
}

}

Hi Monica. It looks like you're just missing the closing bracket for your if block:

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) {
         //Insert exit code
         console.printf("Sorry you must be at least 13 to use this program.\n");
         System.exit(0);
      }    // <- Add this missing bracket
}

Hope that helps:)

Edit: 2 closing brackets were actually missing

}

it doesn't show both brackets inside the cmd prompt screen but it is there

Hi. It is not there in the code you pasted above.

i have a screen shot. it is. not sure why it doesn't show

You need 2 closing brackets after

System.exit(0);

One for the if block and one for the main method, as in the code I included in my previous answer.

Are you able to access my forked ws?

Yes, just post the link here. I'll have a look

it worked!!!! thanks

You're welcome! Glad it's sorted :)

Thanks so much for helping me through this! I'm learning tons

No problem. I'm glad you're enjoying this. Happy coding! :)
