Nov 4, 2013 · In this method you should compare e.g. the number of elements in boths lists. If the lists contain the same number of elements, you can use the previously defined Linked.equals() to compare the lists item by item.

Aug 21, 2022 · Search for an element in a linked list. Approach: When the linked list is provided to us directly, we can use a for loop to traverse through the list and find the element. In case, if we are not allowed to use pre-built libraries, we need to create our very own linked list and search for the element. Examples:

The indexOf() method returns the position of the first occurrence of a value in the list. If the item is not found in the list then it returns -1.

Dec 18, 2024 · In Java, the indexOf() method of the LinkedList class is used to find the index of the first occurrence of the specified element in the list. Syntax of LinkedList indexOf() Method . public int indexOf(Object o); Parameter: This method takes an object “o” as an argument. Return type: It returns the index of the first occurrence of the ...

Nov 4, 2011 · I was wondering if there's a way in java to find the position of a node when I have the specific data value as a parameter. For example, if I wanted to remove the node before or after a specific object within the linked list, how would I do this?

Mar 10, 2020 · Just take one step through the list for each position: public Character getData(int position) { Node current = head; while(position > 0) { current = current.next; position--; } return current.data; }

Jan 3, 2025 · The LinkedList class in Java is a part of the Java Collections Framework and provides a linked list implementation of the List interface. It allows for the storage and retrieval of elements in a doubly-linked list data structure, where each element is linked to its predecessor and successor elements.

Mar 12, 2025 · Write a Java program to iterate over a linked list and print each element along with its position using a loop counter. Write a Java program to implement a recursive function that prints each element and its position in a linked list.

Since java.util.LinkedList is an implementation of a doubly-linked list, these two methods are quite handy to search from either end e.g. indexOf () method starts the search from the head and returns an element's position while lastIndexOf () starts the search from the tail.

May 10, 2022 · How do you find the element of a LinkedList in Java? indexOf () method of List can be used to get the location of an element in the list. Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
