In java,an array is a wrapper class.An array is an object and it gets room in heap.Array can store a collection of data's of same datatype.It can be used to store integers,strings even objects..its collections of data's.Wheather the array stores primitive data,s or objects in it an array s always an object. int numbers[] = new int[10]; this array is of size 10 which can hold 10 int values.This array numbers stores primitive data type but the array number is an object Each item in an array is called an element, and each element is accessed by its numerical index. As shown in the above illustration, numbering begins with 0. The 9th element, for example, would therefore be accessed at index 8.
