Example – Inserting a new item using add() We can insert an item to an ArrayList using the add() function provided by the Kotlin library. In this example, we will be creating two lists: one is "myMutableList" which is a collection of mutable data types, and the other one is "myImm...

To initialize anArrayListwith multiple items in a single line can be done by creating aListof items using eitherArrays.asList()orList.of()methods. Both methods create an immutableListcontaining items passed to the factory method. In the given example, we add two strings, “a” and “b”,...
import java.util.*; public class Main { public static void main(String[] args) { // ArrayList Declaration ArrayList al = new ArrayList(); // By using add() method to add few elements in //ArrayList al.add(10); al.add(20); al.add(30); al.add(40); al.add(50); // Display ...
To add an element in ArrayList, we can use the remove( ) method. This method also has variations. 1 class ArrayList1{ 2 3 public static void main(String args[]){ 4 5 ArrayList<String> ArrayList<String>(); 6 7 arlist.add("JAVA"); 8 9 arlist.add("Cshar...
In this example, we start by importing the ArrayList class from the java.util package. We then create an instance of ArrayList called integerArray to store integers. Here, the add() function is used to add integers (10, 20, 30, and 40 in this case) to the array. Finally, we print ...
1. ArrayList addAll() Method TheaddAll()method first ensures that there is sufficient space in the list. If the list does not have space, then it grows the list by adding more spaces in the backing array. ThenaddAll()appends new elements to the end of the list or at the specified ...
Note that this may not work well with the first approach - a List.of() method creates an unmodifiable list, so if you then do a list.add(), it won't work. So you may need to do additional work to copy the original List to a separate ArrayList, created by you in the builder cla...
