Java arrays initializing after declare

I saw someone initialize and array like this in java

int[] s;

s = new int[]{ and put the list here..}

versus

int[] s = {开发者_StackOverflow the list here} 

Are these both acceptable way of doing it?

Yes, both are equally valid ways of creating a java integer array. The second version is just a shortcut syntax of the first version.

Yes, the latter is a shorthand for the former in a specific case: The latter can only be used directly in an initializer of a variable (where the type is given directly on the left-hand side), whereas the former can be used as an expression in general.

Yes, the actual bytecode generated in both cases is exactly the same.
