A List of elements can be created using multiple ways.Way #1Create a List without specifying the type of elements it can holds. Compiler will throw warning message for it.List list = new ArrayList();Create a List and specify the type of elements it can holds.Way #2List list = new ArrayList();Way #3Create and initialize the list in one line.List list = Arrays.asList(object1, object 2);ExampleFollowing is the example to explain the creation of List objects −package com.tutorialspoint; import java.util.*; public class CollectionsDemo { public static void main(String[] args) { List list = new ArrayList(); list.add("Zara"); ...

We can create a list from a set using its constructor.List list = new ArrayList(set);ExampleFollowing is the example showing the conversion of set to list −package com.tutorialspoint; import java.util.ArrayList; import java.util.HashSet; import java.util.List; import java.util.Set; public class CollectionsDemo { public static void main(String[] args) { Set set = new HashSet(); set.add(1); set.add(2); set.add(3); set.add(4); System.out.println("Set: " + set); List list = new ArrayList(set); System.out.println("List: " + list); } }OutputThis will produce the following result −Set: [1, 2, 3, 4] List: [1, 2, 3, 4]
An element can be copied to another List using streams easily.Use Streams to copy selective elements.List copyOfList = list.stream().filter(i -> i % 2 == 0).collect(Collectors.toList());ExampleFollowing is the example to copy only even numbers from a list −package com.tutorialspoint; import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; public class CollectionsDemo { public static void main(String[] args) { List list = Arrays.asList(11, 22, 3, 48, 57); System.out.println("Source: " + list); List evenNumberList = list.stream().filter(i -> i % 2 == 0).collect(Collectors.toList()); System.out.println("Even numbers in the list: " + evenNumberList); ...

Elements can be checked from a list using indexOf() or contains() methods.Syntax - indexOf() methodint indexOf(Object o)Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.Parameterso − Element to search for.ReturnsThe index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.ThrowsClassCastException − If the type of the specified element is incompatible with ...
