I\'ve got this code but IntelliJ tells me to replace anonymous with lambda but I don\'t know how. can anyone help me with this? Here is my code:

soundVolume.valu         


        

Answer 1

It doesn't really help with the readability but here it is.

Note that main's reference should be final or effectively final for this to work.

soundVolume.valueProperty()
           .addListener(
           (ObservableValue ov, Number old_val, Number new_val) -> {
               main.setSoundVolume(new_val.doubleValue());
               main.getMediaPlayer().setVolume(main.getSoundVolume())
           });
