What is difference between these two array declarations?

Question

It seems these two declarations are the same:

int[] array1 = {11, 22, 33};

and

int[] array2 = new int[] {11, 22, 33};
         


        

Answer 1

Since you are providing the initializer in the same line in which you are declaring, you cam omit the new operator.

// This is OK

int[] i32Array = { 1,2,3,4,5 };

// This is NOT

int[] i32Array; i32Array = { 1,2,3,4,5 };

If your definition and initiation happens in different line you will have to do this

i32Array = new int[] { 1,2,3,4,5 };

So, technically speaking, it is possible to declare an array variable without initialization, but you must use the new operator when you assign an array to this variable
