To insert an item at any position into a linked list object we can use the add(int index, Object o) method. This method takes the index to where the new object to be inserted and the object to be inserted itself. package org.kodejava.util; import java.util.LinkedList; public class LinkedListAddDemo { public static void main(String[] args) { […]
To add an item before the first item in the linked list we use the LinkedList.addFisrt() method and to add an items after the last item in the linked list we use the LinkedList.addLast() method. package org.kodejava.util; import java.util.LinkedList; public class LinkedListAddItems { public static void main(String[] args) { LinkedList<String> grades = new LinkedList<>(); grades.add("B"); […]
To remove the first or the last elements from the linked list we can use the removeFirst() and removeLast() methods provided by the LinkedList class. package org.kodejava.util; import java.util.LinkedList; public class LinkedListRemoveItems { public static void main(String[] args) { LinkedList<String> grades = new LinkedList<>(); grades.add("A"); grades.add("B"); grades.add("C"); grades.add("D"); grades.add("E"); grades.add("F"); System.out.println("Original values are:"); Sy...
The example show you how to retrieve particular object from LinkedList using the indexOf() method. package org.kodejava.util; import java.util.List; import java.util.LinkedList; public class LinkedListIndexOf { public static void main(String[] args) { List<String> names = new LinkedList<>(); names.add("Alice"); names.add("Bob"); names.add("Carol"); names.add("Mallory"); // Search for Carol using the indexOf method. This method // returns the index of […]
This example show you how to use the ListIterator interface to iterate elements of a LinkedList. package org.kodejava.util; import java.util.List; import java.util.LinkedList; import java.util.ListIterator; public class LinkedListListIterator { public static void main(String[] args) { List<String> grades = new LinkedList<>(); grades.add("A"); grades.add("B"); grades.add("C"); grades.add("D"); grades.add("E"); // Retrieves object from LinkedList using the ListIterator // inter...
This example show you how to use the Iterator interface to iterate elements of a LinkedList. package org.kodejava.util; import java.util.List; import java.util.LinkedList; import java.util.Iterator; public class LinkedListIterator { public static void main(String[] args) { List<String> grades = new LinkedList<>(); grades.add("A"); grades.add("B"); grades.add("C"); grades.add("D"); grades.add("E"); // Iterates elements in LinkedList using Iterator. Iterator<String> iterator =...
