Question

The method public void addLast(E obj) of the class LinkedList appends the element specified by the parameter obj to the end of the list.

Options:
a) True
b) False

Answer 1

The given statement, "The method public void addLast(E obj) of the class LinkedList appends the element specified by the parameter obj to the end of the list," is false (B) because the method `addLast(E obj)` of the class `LinkedList` does append the element specified by the parameter `obj` to the end of the list.

Step-by-step explanation:

The `addLast(E obj)` method in the `LinkedList` class precisely does what its name suggests—it appends the specified element to the end of the list. This method navigates through the list until it finds the last node and then adds the new element after that node, effectively extending the list. By utilizing this method, you can consistently add elements to the end without altering the existing sequence.

This operation is particularly useful for maintaining the order of elements within the list, ensuring that newly added elements consistently appear at the list's end. Hence, whether you're implementing a queue, managing elements in a specific sequence, or simply needing to consistently add items to the end of a linked list, the `addLast()` method serves as a dependable option.

Correct Answer: False (b)
