The object of an Array contains a number of variables,called as the components of array.These variables are referenced by array access expressions that use non negative integer index values. If an array has n components, then you can say n is the length of the array. The components of the array are referenced using integer indices from 0 to n - 1.All the components of an array have the same type, called the component type of the array. If the component type of an array is arr, then the type of the array itself is written arr.The component type of an array may itself be an array type.
