The expression of an array is the name of the array followed by the index of the particular element in the square bracket.

The first element in every array has an index of zero.

Every array object knows its own length and the length of an array can always be changed.

An indexed array name is an array-access expression.

Elements of the arrays can be either primitive or reference types.

The highest index in an array is one less than the number of elements in the array.
