Does an array object explicitly contain the indexes?

Question

Since day one of learning Java I\'ve been told by various websites and many teachers that arrays are consecutive memory locations which can store the specified number of data al

Answer 1

The "consecutive memory locations" is an implementation detail and may be wrong. For example, Objective-C mutable arrays do not use consecutive memory locations.

To you, it mostly doesn't matter. All you need to know is that you can access an array element by supplying the array and an index, and some mechanism unknown to you uses the array and the index to produce the array element.

There is obviously no need for the array to store indexes, since for example every array in the world with five array elements has the indexes 0, 1, 2, 3, and 4. We know these are the indexes, no need to store them.
