ArrayList of int array in java

To create an ArrayList of int arrays in Java, you can use the following syntax:

List<int[]> list = new ArrayList<>();

This creates an ArrayList that can hold arrays of int values. You can add an int array to the list using the add method:

int[] array = {1, 2, 3};

You can also create an ArrayList of Integer objects, which allows you to use the add and get methods of the ArrayList class to add and retrieve Integer values, respectively.

List<Integer> list = new ArrayList<>();

int value = list.get(0);  // value is 1

I hope this helps! Let me know if you have any questions.
