var arr:[int] this is fixed size array and don't change size after initialization.

var arr=Array() this is array list and this array change the size with respect to number of elements. you can easily remove and add element easily in this array.

var arr:[Int] This one simply declares an array of Integers named arr. It does not initialise the array and hence is not usable.

var arr=Array() This one declares as well as initialises the array. We can add whatever we want to this arr.

The second one is better since its initialised and usable.
