"double[] array = {1,2,3,4};" vs "double[] array = new double[]{1,2,3,4,};"

Question

I have been programming for quite sometime and I came across something I never noticed before.

What is the difference between these two?

double[] nums = {1,2,3,4};
double[] nums2 = new double[]{1,2,3,4,};

They both compile and have the same properties. At first I thought that nums2 could accept a new int[] and have integer values in it since its lower down in the hierarchy. But It actually didn't work.

The difference is that you can only use the former syntax when declaring a variable. You can use the latter syntax anywhere. — Andy Turner, Apr 08 '18 at 19:14

The first way is just a shortcut syntax to create and initialize an array of the second way.

This is the only difference.

Take a look at https://docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html
