チームを設定するために使用するguiがあり、各チームに2人のエンジンと2つのエンジンと1つの機械と1つのAerodinamic plus 1は最も戦略的です。 私たちのguiではすべてを設定し、上記のそれぞれの値を初期化します。私たちのGUIはある種のレースシミュレーションであり、勝者を返すことになっています。私たちはGUIをコンパイルスレッド「JavaFXアプリケーションスレッド」のJava例外を修正しようとしています。java.lang.NullPointerException
しかし毎回、私たちはこのエラーを取得：私たちはどのように、なぜ何かがゼロであり、我々はそれをdebuged、すべてがデバッグで（正常に動作しますようです知らないので

これは本当に奇妙です）しかし、あなたが単にmainメソッドを実行すると、これらのすべてのエラーが発生します。
我々は我々が持っているレースをシミュレートするための方法出法で
public double calcRisk(TDriver td) {
double risk = MIN_RISK;
risk += td.getCar().getSetupStrategy();
risk += (100 - td.getTeam().getStrategist().getProficiency());
return risk;
}
ともあります：
double crashRisk = calcRisk(td);
and this method:
private void beginRace() {
int raceNumber = Interact.game.getChamp().getNumber();
System.out.println("RN " + raceNumber);
StartInterac.game.getCham().simulateNextRace();
rScene();
}
をし、次のエラーは、次の方法である：
private void raceStartScene() {
.....rest of the code.......
raceBtn.setOnAction(e -> {
beginRace();
});
......rest of the code......
}
編集：
私たちは、この方法のためにチェック入れDriverPerTeam
と呼ばれるクラスに位置していますgeeTeam amethodています
public double calcRisk(TDriver td) {
System.out.println("---check----");
System.out.println("1 "+td.getTeam());
System.out.println("2 "+td.getTeam().getStrategist());
System.out.println("3 "+td.getTeam().getStrategist().getProficiency());
System.out.println("-------------");
double risk = MIN_RISK;
risk += td.getCar().getSetupStrategy();
risk += (100 - td.getTeam().getStrategist().getProficiency());
return risk;
}
を、今ではこのような答えを返します。

誰でも助けることができるのこの状況で私？
