如何设置和获取SimpleStringProperty数组

Question

我正在尝试使用javafx bean设置并获取某些字段的值。问题是我能够使用“StringProperty specialization”但不能使用“StringProperty degrees []”这是一个字符串属性数组，因为下面代码中的set方法不起作用：

   private StringProperty degrees[];
  //getter and setter for degrees array

   public final void setDegrees(String[] degrees) {

    **this.degreesProperty().set(degrees);**
} 
 public final StringProperty[] degreesProperty() {

    if (degrees == null) {
        SimpleStringProperty degree[]=new SimpleStringProperty[100];
        degree[0]=new SimpleStringProperty("");
        degree[1]=new SimpleStringProperty("");
        degrees =degree;
        return degrees;
    } else {

        return degrees;
    }
}

下面的代码工作正常：

     private StringProperty specialization;

    //getter and setter for specialization
    public final void setSpecialization(String specialization) {
    this.specializationProperty().set(specialization);
}

public final StringProperty specializationProperty() {

    if (specialization == null) {

        specialization = new SimpleStringProperty("");
        return specialization;
    } else {

        return specialization;
    }
}

public final String getSpecialization() {

    if (specialization != null) {
        return specialization.get();
    } else {
        return "";
    }
}
