    set/setValue and get/getValue methods pairs exist to align Object properties with primitive types properties like BooleanProperty or DoubleProperty:

    BooleanProperty:

    void set(boolean value)
    void setValue(java.lang.Boolean v)
    

    DoubleProperty:

    void set(double value)
    void setValue(java.lang.Number v)
    

    In these property classes ___Value methods work with corresponding to type objects while direct methods work with primitive types.

    Looking in the code you may find a bit of a difference in the logic. For example, DoubleProperty#setValue(null) is equal to DoubleProperty#set(0.0) (which was required by binding). So generally I'd advise to use set/get methods and leave setValue/getValue to binding needs as they may incorporate additional logic.

    For Object/String properties there is no difference between set and setValue methods.
