Is there any difference between ways we are declaring arrays?

Question

• int[] a = new int[] {1, 2, 3};

And

• int[] a = {1, 2, 3};

Are there any practical differences between those?

Answer 1

They are equivalent, no difference between the two.

new keyword creates an object.. and you're creating.. an array, which is an object.

See Chapter 10. Arrays:

In the Java programming language, arrays are objects (§4.3.1)...
