Java: Why can't return array using {..} without new operator?

Question

I have searched a lot on the website, but didn\'t find any related question. So I believe it is not a duplicate.

I know we can initialize an array with 3 ways:

Answer 1

char[ ] charAr=new char[10];

Is a proper array declaration. You could assign charAr to another char array.

char[ ] charAr=new char[]{'a','b','c'};

Syntax where you do both declaration and initialization in one line. You can reassign this to a new char array.

char[ ] charAr={'a', 'b', 'c'};

Is a array literal. You can assign literal value only where you define the array. You cannot reassign this to a new char array.

You cannot return array literals because during compile time, the compiler does not know the type of elements you are returning.
