Daniel Stallard

Hey are you using an IDE  like net beans or eclipse. When I was first starting to learn Java  i waould use the debugger to walk me through code I was having issues with. This really helped me understand what the code was doing step by step. I'm still learning an I still use the debugger to help me grasp code better.

This is my error i get when i run it it prints the riddle in the ide and the answer

I changed my riddle class
so now
if i do a system.out.print(rr) i get the riddle but givenriddle.setText still blows up.

here is my updated code

The Controller:

   @FXML private Label givenRiddle;    @FXML private TextArea answer;    @FXML private Label result;    @FXML private Label correct;    @FXML private Label worng;    @FXML private Label play;    @FXML private Label stop;    @FXML private Label riddleAnswer;                @FXML    private String answerButtonAction() {        String r = "";        if(answer.getText().equalsIgnoreCase(riddleAnswer.getText())){            result.setText("Good Job!!");            r = "c";        }        else{            result.setText("Wrong");            result.setText("The correct answer was: "+ riddleAnswer.getText());            r = "w";        }        return r;    }        @Override    public void initialize(URL url, ResourceBundle rb) {        // TODO        int c = 0;//Keeps count of correct answers        int w = 0;//Keeps count of wrong answers                ArrayList<Riddle> r = new ArrayList<Riddle>();        r = RiddleMethods.readText(r);        for(int i =0;i<r.size();i++){            while(i<5){                Riddle rid = r.get(i);                String rr = rid.getRiddle();//Is the wanted string                String ra = rid.getAnswer();//Is the wanted string                givenRiddle.setText(rr);//turns to null value you here                riddleAnswer.setText(ra);//turns to null value you here               String results = answerButtonAction();                if(results.equalsIgnoreCase("c")){                    c++;                }                else{                    w++;                }            }        }        correct.setText("You Got "+ c +" corret.");        worng.setText("You Got "+ w +" wrong.");            }

my riddle class

public class Riddle {    private SimpleStringProperty Riddle;    private SimpleStringProperty Answer;        //Empty Constructor    public Riddle(){            }        //Full Constructor.    public Riddle(String Riddle,String Answer){        this.Riddle = new SimpleStringProperty(Riddle);        this.Answer = new SimpleStringProperty(Answer);    }    public String getRiddle() {        return Riddle.get();    }    public void setRiddle(SimpleStringProperty Riddle) {        this.Riddle = Riddle;    }    public String  getAnswer() {        return Answer.get();    }    public void setAnswer(SimpleStringProperty Answer) {        this.Answer = Answer;    }
i used the simp;e string property casue thought it may work but it dont.Least i dont see where it has chaged anything so i may put the Riddle and Answer var back to a string

true i could do that didnt think about it that way but i did get rid of that error but now im having an issue with when i try to get the label to display the riddle it has a null value and not the string.The string is a sting up til i try to put it in the givenriddle variable then it turns to null and blows up

the one should be an i So it should be while i is less than 5. The reason i have that is cause i only wana give them five riddles than ask if they wanna play again

Sorry i thought i did put te error in there im getting an error on line 20 in the fxml file its says something about it not being in the root

Hey, guys, I'm trying to get this program to work I got a text file it will read in and then it will cycle through the array list of riddle and give one at a time the user answers it to see if they get it right. For now, I'm just trying to get it to display the riddle and check to see if the answer is right. I'm using Java scene builder I'm just now playing with it.So I'm lost on a lot of it but from what I have seen and read I don't understand why this doesn't work.

This is the Controller

import java.net.URL; import java.util.ArrayList; import java.util.ResourceBundle; import javafx.event.ActionEvent; import javafx.fxml.FXML; import javafx.fxml.Initializable; import javafx.scene.control.CheckBox; import javafx.scene.control.Label; import javafx.scene.control.TextArea; /** * * @author Daniel */ public class FXMLDocumentController implements Initializable {        @FXML private Label givenRiddle;    @FXML private Label riddleAnswer;    @FXML private TextArea answer;    @FXML private Label result;    @FXML private Label correct;    @FXML private Label wrong;    @FXML private CheckBox play;    @FXML private CheckBox stop;        @FXML    public void answerButtonAction(String input,String riddleAnswer) {        if(input.equalsIgnoreCase(riddleAnswer)){                    result.setText("Good job!!!");                                  }                else{                    result.setText("Wrong answer. Let's try the next one.");                                    }    }        @Override    public void initialize(URL url, ResourceBundle rb) {        // TODO        ArrayList<Riddle> r = new ArrayList<Riddle>();        r = RiddleMethods.readText(r);        for(int i = 0;i<r.size();i++){           while(1<5){               Riddle rid = r.get(i);               givenRiddle.setText(rid.getRiddle());               String an = answer.getText();               String ridanswer = rid.getAnswer();               answerButtonAction(an,ridanswer);                                               }                         }        }    }

This is the FXML Document

which is where I get an error line 20

This is the start stage

import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.stage.Stage; public class DStallardRiddleMeUp extends Application {        @Override    public void start(Stage stage) throws Exception {        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));                Scene scene = new Scene(root);                stage.setScene(scene);        stage.show();    }    /**     * @param args the command line arguments     */    public static void main(String[] args) {        launch(args);    }     }

Any help would be great id like to learn to put graphics with my code.

okay cool deal i have used scratch jr with the youngest. Its on her tablet she likes it alot an what ive seen it was easy to grasp an navigate si i figured scratch was the same.

does it ggive you steps on installing the software?

awsome so it would be grat for my 12 year old that loves video games?

Whzt type of material is covered? is it just basic material or do you cover more as in like small animations or anything like that?

So how approachable would you say this is for beginners?

so in what thread do we get to ask questions

Wellcome to the ranch!!!
