Hi,
Array: Array has fixed in size. We can't insert the values in between the arrays Also we can't remove the values form middle of an arrays. There is no boxing and unboxing process on ArrayCollections: Collection has dynamic in size. We can insert item in between of the collection We can remove an item from middle of collection There is process of Boxing and Unboxing on Collection.

Array:
Use an array when the number of elements that need to be inserted into the array is known at compile time and it remains fixed throughout the execution of the program.
You can store elements of same type only in an array. Unless you declare an array of type 'Object' (involves boxing, unboxing efforts)
You can store basic data types in an array.
Collection:
Use a collection when you do not know how many elements you will need to store. A collection can grow in size dynamically.
In a collection you can store any type of elements provided they are all objects.
You can store objects in a collection.
