Java Java Objects Harnessing the Power of Objects Method Overloading

Method overloading with same parameters in different order

I am curious that if I have 2 methods like:

public void name(String s, int a, double d){ }

public void name(double d, String s, int a) { }

Are these 2 methods legal? Is this allowed in Java? I'm mainly just curious. What if I wanted to write different code in each? would I need to then create 3 separate methods for this? Thanks! :)

Yes, it is completely legal to have the same parameters in different order when overloading in Java.

Amazing. I see it as cascading method calls like CSS fx; so if I call 'Fill' with no arguments it'll act normal, if I add one argument it can seamlessly cascade to the method with that one argument handling. beautiful.
