Why array is using new ?

Question

when array is declared a new word is used in Java

Answer 1

It allocates the memory that will hold the array. Usually, if you hate the new keyword, and know the exact elements, you can use the shortcut method, like:

int[] arr = {4, 5, 6, 7};

You are explained the 'new' keyword here in detail:

Answer 2

You need "new" keyword if you want to use an array without initialising it. It provides the compiler a heads up to how much memory it might require
