This tutorial demonstrates the use ofArrayList, Iterator and a List. There are 7 ways you can iterate through List. Simple For loop Enhanced For loop Iterator ListIterator While loop Iterable.forEach() util Stream.forEach() util Java Example: You need JDK 13 to run below program aspoint-5...
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
In Java, every ArrayList has aforEachmethod, which is one of the simplest ways to loop through all the items just like theforloop. Like the previous example, we can get the names fromModelClassusing thegetName()method. importjava.util.ArrayList;importjava.util.Arrays;importjava.util.function...
You can iterate over the ArrayList elements through multiple methods: // simple `for` loop for (int i = 0; i < foods.size(); i++) { System.out.println(foods.get(i)); } // for each loop for (String item : foods) { System.out.println(item); } // Java 8 `forEach` from ...
1. Different Methods to Loop Through a List We are listing down 4 different ways which are in my knowledge. 1.1. Stream API Java 8 Stream APIprovides ways to iterate over a collection and operate over each element.Streamcan be used as analternative to the for-loop. ...
As soon as, thecounterreaches 6, the loop terminates. intcounter=1;while(counter<=5){System.out.println(counter);counter++;} Program output. 12345 2.2. Iterate through aList The following Java program iterates over anArrayListusing itsiteratorin thewhileloop. ...
Print List in Java Using the Enhanced for Loop One of the simplest and most readable methods to iterate through list elements is using the enhanced for loop. The enhanced for loop, also known as the for-each loop, simplifies the process of iterating through collections, including lists. Its...

In this tutorial, you will learn how to remove element from Arraylist in java while iterating using different implementations provided by Java. It is necessary to understand the right way to remove items from a List because we might encounter errors in our programs if not done correctly. For...
To filter a list in Java, we either use a for loop and an if condition or we utilize the stream's filter method. Filter a list of integersIn the first example, we filter a list of integers. Main.java import java.util.List; import java.util.ArrayList; void main() { var vals = ...
