An array in Java is an object. In Java, we can create arrays by using new operator and we know that every object is created using new operator. Hence we can say that array is also an object.
Collection only works on anything which is Object. int is the primitive datatype and int[] is the Object.
That is the reason ArrayList is not allowed but ArrayList is allowed.

I am not able to figure out why ArrayList<int> is not allowed but ArrayList<int[]> is allowed.
I was under the impression that primitive data types are not allowed in Collections, so why is this legit?
