If one was to want such a data structure, one should investigate less RAM intensive approaches such as databases, sparse arrays, and the like. If you were to try to instantiate an array list of this magnitude, you would have a structure that is at least 8 gigabytes - this only accounts for MAX_INT pointers, and not the additional space of the data at each point.Īttempting to access beyond the maximum value allowed through an iterator associated with the array would likely result in one of OutOfMemoryException, IndexOutOfBoundsException or a NoSuchElementException depending on implementation. You can't make an ArrayList (or for that matter an int array) that has a long for its index.

The specifics of what the maximum size of the array or ArrayList differe based upon the implementation of the JVM (which may be lower than the MAX_INT value). ArrayList - Kotlin Programming Language Common JVM JS Native Version 1.8 kotlin-stdlib / llections / ArrayList ArrayList Common 1.2 class ArrayList : MutableList, RandomAccess (source) JVM 1.1 typealias ArrayList ArrayList (source) JS 1.

That is the largest possible value that can be accessed in an ArrayList.

int is a signed 32 bit value, with a maximum value of 2,147,483,647.
