In this article, we will learn to iterate list in our Java application. There are many ways to iterate list. List can be iterated using its forEach method that will use lambda expression as an argument.
The code demonstrates how to iterate over a 2D list (list of lists) in Java by using nested for-each loops. It prints the elements of each inner list in the desired format. Algorithm Step 1 Import necessary libraries for the code. Step 2 Create the "iterateUsingForEach" function, which...
How to iterate using Interator when the parameter of List is an object of another user defined class. Say you pass the objects of type book in the List and iterate. itr.next() prints the reference and takes the ptr to next location. how to print the fields of the object? for eg ID,...
Since version 8, Java has introduced theStream APIand lambdas. Next, let’s see how to iterate a map using these techniques. 5.1. UsingforEach()and Lambda Like most other things in Java 8, this turns out to be much simpler than the alternatives. We’ll just make use of theforEach()...
A linked list is a data structure that consists of a sequence of nodes, where each node stores an element and a reference to the next node. In Java, the
If the path is a Java System Property it is replaced by its value in the running VM. The following properties are translated: user.home - User's home directory user.dir - User's current working directory java.io.tmpdir - Default temp file path--><diskStorepath="java.io.tmpdir"/><!-...

The following is an example to iterate through Decade Tuple in Java Example import org.javatuples.Decade; public class Demo { public static void main(String[] args) { // Tuple with 10 elements Decade<String, String, String, String, String, String, String, String, String, String> d = De...
Java Code:import java.util.LinkedList; public class Exercise2 { public static void main(String[] args) { // create an empty linked list LinkedList<String> l_list = new LinkedList<String>(); // use add() method to add values in the linked list l_list.add("Red"); l_list.add("...
This post will discuss various ways to iterate a list in reverse order in Java without actually reversing the list.. The `List` interface provides a special iterator, called ListIterator, that allows bidirectional access
