假设JavaFX类具有一个名为weight的绑定属性,其类型为DoubleProperty。 按照惯例,该类中定义了以下哪些方法?
A: public double getWeight()
B: public void setWeight(double v)
C: public DoubleProperty weightProperty()
D: public double weightProperty()
E: public DoubleProperty WeightProperty()
A: public double getWeight()
B: public void setWeight(double v)
C: public DoubleProperty weightProperty()
D: public double weightProperty()
E: public DoubleProperty WeightProperty()
举一反三
