Java Add elements to a LinkedList

To add elements to a LinkedList in Java, you can use the add method of the LinkedList class.

The add method adds a new element to the end of the LinkedList, and it takes a single argument that specifies the value of the element to be added.

Here is an example of how you can add elements to a LinkedList in Java:

import java.util.LinkedList;

public class Main {
  public static void main(String[] args) {
    // Create a LinkedList
    LinkedList<String> list = new LinkedList<>();

    // Add some elements to the LinkedList
    list.add("Apple");
    list.add("Banana");
    list.add("Orange");

    // Print the LinkedList
    System.out.println(list);  // Output: [Apple, Banana, Orange]
  }
}

In this example, the list variable is a LinkedList that stores strings.

The add method is used to add three elements to the LinkedList: "Apple", "Banana", and "Orange".

Then, the list variable is printed, and it contains the three elements that were added to the LinkedList.

It is important to note that the add method adds the element to the end of the LinkedList, and it always returns true.

Therefore, you can use the add method to append elements to the LinkedList, but you cannot use it to insert elements at a specific position in the LinkedList.

To insert an element at a specific position in a LinkedList, you can use the add method of the List interface, which takes two arguments: the index at which the element is to be inserted, and the element to be inserted.

Here is an example of how you can insert an element at a specific position in a LinkedList:

list.add(1, "Peach");

In this example, the element "Peach" is inserted at the index 1, which is the second position in the LinkedList.

After this operation, the LinkedList contains the following elements: "Apple", "Peach", "Banana".
