LinkedList: [Cat, Dog, Horse] First Element: Cat Last Element: Horse In the above example, we have used the LinkedList class to implement the linked list in Java. Here, we have used methods provided by the class
The Arrays class in the java.util package provides a utility method to convert an array to a List. The Arrays.asList() method will convert an array to a fixed size List. To create a LinkedList, we just need to pass the List to the constructor of the java.util.LinkedList class. 6th...

• Using built-in Java classes, such as ArrayList and LinkedList, is not allowed.• Do not forget the issue of managing the “real estate” (i.e., the fixed size of the array) in the case of thenumArrayList implementation.2. Write a class called numSet that uses one of your ...
