Question

******Java Programming

Hi guys,

I really need you help. I created a code for my java course, but it keep giving me error messages. Majority of my code is fine but some keep display error on my console. I was hoping someone could pin points the problem. .There are three classes with the testCenter class being the main class. In the following is the assignment, and the bottom is my code. Please help!

Assignment:

Concepts:

GUI

User Design

Graphics

Deployment

Programming Project:

Create a GUI using Swing or Spring Boot for one of the previous programming projects. Convert all console input/output to be used in a GUI. Follow standard programming practices for the design of the GUI.  See this link for more details (Links to an external site.)

. Have fun with it.

Submission:

Submit the executable jar file so that I can run your program.  See this link on how to make an executable jar file.

Animal Class (I place error messages where the problems accures)

//error message

package testCenter;

//error message across the five javafx

import javafx.application.Application;

import javafx.scene.Scene;

import javafx.layout.Stackpane;

import javafx.scene.text.Text;

import javafx.stage.Stage;

//error message

public class Animal implements Runnable {

static boolean winner;

private String name;

private int position;

private int speed;

private int rest;

private Food food;

String read;

public Animal(String name, int pos, int speed, int rest, Food food) {

winner = false;

this.name = name;

this.position = pos;

this.speed = speed;

this.rest = rest;

this.food = food;

}

public void lamborgini() { //run

while(position < 100 && !winner) {

position += speed;

System.out.println(this);

food.eat(rest, read);

}//End of while loop.

winner = true;

System.exit(0);

}//End of void

public int getPosition() {

return position;

}

public String toString(){

read = "Player: " + name + "\nCurrent position in race: \n" + position;

return read;

}

}//end of class

Food Class:

import org.w3c.dom.Text;

class Food {

//error message

Text Message = new Text();

public synchronized void eat(int timeMachine, String textMsg) {

try {

//error message

Message.setText(textMsg + "I'm currently eating.");

System.out.println("I'm currently eating.");

Thread.sleep(timeMachine * 20);

//error message

Message.setText(textMsg + "I'm currently eating.");

System.out.println("I'm done eating.");

} catch(InterruptedException e){

e.printStackTrace();

}

}

} //end of class.

Test Center class:

//error message

public class testCenter extends Application {

//error message

public void start(Stage superStar) {

Food food = new Food();

Animal turtle = new Animal("Turtle", 0, 3, 100, food);

Animal rabbit = new Animal("Rabbit", 0, 5, 150, food);

Thread turtleT = new Thread(turtle);

Thread rabbitR = new Thread(rabbit);

turtleT.start();

rabbitR.start();

//error message

StackPane goGirl = new StackPane();

goGirl.getChildren().add(food.Message);

//error message

Scene action1 = new Scene(goGirl, 350, 200);

superStar.setScene(action1);

superStar.show();

}

public static void main(String[] args) {

//error message

launch(args);

}

} //end of class

Answer 1

It would have been easier if you included what the error messages were as well as the position. Its hard to fix the errors wirhout knowing what exactly they are. I'll provide a possible fix based on the errors I got while running the code.

1. Make sure the package name and the parent folder name are correct. Make sure you created a Java package properly.

2.You need to have JavaFX installed to import it. You can get the jar files and install it easily.

3. You dont need Animal to implement Runnable since it is not an abstract function.

4. You might have imported the wrong Text class. There is a JavaFX Text class as well. Install JavaFX and try including that. If it still doesnt work try using a JLabel instead.

5.You probably got this error because the Text you imported doesnt have a setText method. The above step should fix it.

6.Your class Food should extend Thread or implement Runnable if you want to use Threads.

7. The next few errors may be caused by a mistake in extending Application.

Again, this is merely speculation based on the errors I got. If this doesnt fix it include the error messages as well.
