Java - LinkedList Methods Part 2: Accessing Elements

Accessing elements in a LinkedList is straightforward with methods like get(), getFirst(), and getLast().

Examples and Explanation

Using get()

System.out.println(list.get(2)); // Output: Apple

Explanation: Retrieves the element at the specified index.

Using getFirst()

System.out.println(list.getFirst()); // Output: Cherry

Explanation: Efficiently retrieves the first element, useful for queue operations.

Using getLast()

System.out.println(list.getLast()); // Output: Grape

Explanation: Fetches the last element, useful in stack or deque contexts.

Using a Loop

for (String item : list) {

    System.out.print(item + " ");

}

// Output: Cherry Elderberry Apple Banana Date Fig Grape

Explanation: Access elements sequentially for processing or display.

Random Access Example

System.out.println("Middle Element: " + list.get(list.size() / 2)); // Output: Banana

Explanation: Retrieves an element based on calculated index, like the middle element.
