java - difference between these 2 ways of initializing an simple array

Question

In java, I can initialize an array with predefined content either by :

int[] myArr = new int[]{1,2,3};

Or by :

int[] myArr = {1,2,3};

Essentially, is there any difference between these two ways ? Are they completely identical in Java ? Which way is better and why?

Answer 1

is there any difference between these two ways ? Are they completely identical in Java ?

No there is no difference. Both of them will create an array of length 3 with the given values.

The 2nd one is just a shorthand of creating an array where you declare it. However, you can't use the 2nd way of creating an array, at any other place than the declaration, where the type of array is inferred from the declared type of array reference.
