Please answer the question example in Java programming

1. Dynamic Array You need to understand the implementation of this data structure, especially for the methods, such as get, set, append, insert, remove, and resize. Exam question example: the current version of dynamic array will double its capacity when the array is full. If we want it to shrink its size when it has fewer elements, what methods of the dynamic array need to be changed? 2. Singly Linked List You need to understand the implementation of Singly Linked List, and you need to know how to navigate a Singly Linked List. Exam question example: suppose we have a singly linked list, which has more than two integers. Please finish the following method to find the first number that's not in ascending order. For example, given a list {1, 2, 3, 4, 4, 1, 2,3}, the method should return 5, because at index 5, 1 is less than the previous node. If the list is in ascending order, the method should return -1. Exam question example: Compare the get method of dynamic array and the get method of Singly Linked List, which method is faster? Why? 3. Doubly Linked List You need to understand the implementation of Doubly Linked List, and you need to know how to navigate a Doubly Linked List. Exam question example: suppose we have a doubly linked list, which has more than three nodes. Please finish the following method to replace the second node with the given node, newNode
