Java LinkedList Print

LinkedList is a class in Java that represents a linked list. A linked list is a data structure consisting of a group of nodes in which each node points to the next node in the sequence.

To print a LinkedList in Java, we can use the toString() method of the LinkedList class or we can traverse the list using a loop and print each element.

Using toString() Method

LinkedList<String> linkedList = new LinkedList<>();
linkedList.add("John");
linkedList.add("Mike");
linkedList.add("Lisa");

String linkedListAsString = linkedList.toString();
System.out.println(linkedListAsString);

Output:

[John, Mike, Lisa]

Using a Loop

LinkedList<String> linkedList = new LinkedList<>();
linkedList.add("John");
linkedList.add("Mike");
linkedList.add("Lisa");

for(String element: linkedList) {
    System.out.println(element);
}

Output:

John
Mike
Lisa

In this example, we use a for-each loop to iterate over the elements in the LinkedList and print each element.

We can also use a traditional for loop to traverse the LinkedList:

for(int i = 0; i < linkedList.size(); i++) {
    System.out.println(linkedList.get(i));
}

Output:

John
Mike
Lisa

In this example, we use the get() method of the LinkedList class to retrieve the element at a given index.

Overall, there are multiple ways to print a LinkedList in Java, and the chosen approach depends on the specific requirements of the program.
