      IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size())

    • forEach

      public void forEach(IntConsumer action)
      Performs the given action for each element of the list.
      Parameters:
      action - the action to be performed for each element
      Throws:
      NullPointerException - if the specified action is null

    • stream

      public IntStream stream()
      Returns a sequential IntStream with the specified list as its source.
      Returns:
      a sequential IntStream

    • add

      public void add(int element)
      Appends the specified element to the end of this list.
      Parameters:
      element - element to be appended to this list

    • add

      public void add(int index, int element)

      Parameters:
      index - index at which the specified element is to be inserted
      element - element to be inserted
      Throws:

    • addAll

      public boolean addAll(int[] elements)
      Appends all of the elements in the specified array to the end of this list.
      Parameters:
      elements - array containing elements to be added to this list
      Returns:
