Arrays don't have a "toList" function, so we need "Arrays.asList" helper functions to do the conversion.
This is quite odd: List has its own function to convert to an array, but arrays need some helper functions to convert to a List. Why not let arrays have a "toList" function, and what's the reason behind this Java design?
Thanks a lot.
Because List instances are an actual object, while arrays are (for MOST intents and purposes) a primitive and don’t expose methods. Although technically arrays are an object which is how they can have a field
length and a method call such as
clone(), but their classes are created after compilation by the JVM.
