Solution

The Java code you provided creates a LinkedList of Strings and adds three elements to it: "Cat", "Dog", and "Rabbit". Then it prints out the size of the LinkedList.

Here's a step-by-step explanation:

  1. LinkedList<String> ll = new LinkedList<String>(); This line initializes a new LinkedList of Strings and assigns it to the variable ll.

  2. ll.add("Cat"); This line adds the String "Cat" to the LinkedList.

  3. ll.add("Dog"); This line adds the String "Dog" to the LinkedList.

  4. ll.add("Rabbit"); This line adds the String "Rabbit" to the LinkedList.

  5. System.out.println(ll.size()); This line prints out the size of the LinkedList, which is 3 because we added three elements to it.

Both array and LinkedList in Java have indexes that allow elements to be accessed by their position within the collection. When you should choose to use LinkedList rather than array?AWhen you frequently perform addition and removal of data at any point of the collection.BWhen you frequently search for a value from the collection.CWhen you frequently update the existing values in the collection.DWhen you want print all values in the collection.
