      • newArrayList

        public static <E> java.util.ArrayList<E> newArrayList()
        Returns a new mutable, empty ArrayList instance.

      • newArrayListWithCapacity

        public static <E> java.util.ArrayList<E> newArrayListWithCapacity​(int initialArraySize)
        Creates an ArrayList instance backed by an array of the exact size specified; equivalent to ArrayList(int).
        Parameters:
        initialArraySize - the exact size of the initial backing array for the returned array list (ArrayList documentation calls this value the "capacity")
        Returns:
        a new, empty ArrayList which is guaranteed not to resize itself unless its size reaches initialArraySize + 1
        Throws:
        java.lang.IllegalArgumentException - if initialArraySize is negative
