    Post Are arraylists redundant?

    If an array in java is re-sizeable and can contain primitive data types as well as objects, what is the point of an arraylist? Take this array of random ints for example:

    int[] intArray = {5, 243, 6766, 2, 23498, 4};

    I can add or delete however much I want from this array, so what is the point of an arraylist?

    Default Re: Are arraylists redundant?

    Arrays are static elements which means that once defined the space cannot be changed. Instead the arraylists are dynamic that is the space can vary. For example if you have an arraylist in which you save user accounts for each account you should increase the space by 1 instead with the array you must immediately declare a default size.
