Question: Implement a nested class DoubleNode for building doubly-linked lists, where each node contains a reference to the item preceding it and the item following it

Implement a nested class DoubleNode for building doubly-linked lists, where each node contains a reference to the item preceding it and the item following it in the list (null if there is no such item). Then implement methods for the following tasks:

  • Insert at the beginning

  • Insert at the end

  • Remove from the beginning

  • Remove from the end
