Technically, there is a way to do without iterating through the array -- you can skip generating the array in the first place.... Using Java 8 Streams. Java 8 streams also provide a simple way to transform an array to the List. In this, we create a stream of array and get the list using the collector Collectors.toList() but there is a twist if we are converting an array of primitives i.e. int, float, long etc then we have to use an extra intermediate function ( boxed
