To check if ListDictionary contains a specific key, the code is as follows −Example Live Demousing System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { ListDictionary dict1 = new ListDictionary(); dict1.Add("A", "Books"); dict1.Add("B", "Electronics"); dict1.Add("C", "Smart Wearables"); dict1.Add("D", "Pet Supplies"); dict1.Add("E", "Clothing"); dict1.Add("F", "Footwear"); Console.WriteLine("ListDictionary1 elements..."); foreach(DictionaryEntry d in dict1) { Console.WriteLine(d.Key + " " + d.Value); } ...

To get an enumerator that iterates through HashSet, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { HashSet set1 = new HashSet(); set1.Add("A"); set1.Add("B"); set1.Add("C"); set1.Add("D"); set1.Add("E"); set1.Add("F"); set1.Add("G"); set1.Add("H"); Console.WriteLine("Elements in HashSet1..."); foreach (string res in set1) { Console.WriteLine(res); } HashSet set2 = new ...

To remove all classes, use the removeClass() method with no parameters. This will remove all of the item's classes.ExampleYou can try to run the following code to remove all CSS classes using jQuery:Live Demo jQuery Selector $(document).ready(function() { $("#button1").click(function(){ $("p").removeClass(); }); }); .red { color:red; } .blue { color:blue; } This is first paragraph. This is second paragraph. Remove
A lambda expression is an anonymous method and doesn't execute on its own in java. Instead, it is used to implement a method defined by the functional interface. A lambda expression used with any functional interface and Comparator is a functional interface. The Comparator interface has used when sorting a collection of objects compared with each other.In the below example, we can sort the employee list by name using the Comparator interface.Exampleimport java.util.ArrayList; import java.util.Collections; import java.util.List; class Employee { int id; String name; double salary; public Employee(int id, String name, double salary) { super(); ...

To get the number of nodes contained in the LinkedList, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main() { LinkedList list = new LinkedList(); list.AddLast("A"); list.AddLast("B"); list.AddLast("C"); list.AddLast("D"); list.AddLast("E"); list.AddLast("F"); list.AddLast("G"); list.AddLast("H"); list.AddLast("I"); list.AddLast("J"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("First Node = "+list.First.Value); list.Clear(); ...

To check if HybridDictionary has fixed size, the code is as follows −Example Live Demousing System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main() { HybridDictionary dict1 = new HybridDictionary(); dict1.Add("A", "Books"); dict1.Add("B", "Electronics"); dict1.Add("C", "Smart Wearables"); dict1.Add("D", "Pet Supplies"); dict1.Add("E", "Clothing"); dict1.Add("F", "Footwear"); Console.WriteLine("HybridDictionary1 elements..."); foreach(DictionaryEntry d in dict1) { Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("Is ...

To add new node or value at the end of LinkedList, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main() { LinkedList list = new LinkedList(); list.AddLast("A"); list.AddLast("B"); list.AddLast("C"); list.AddLast("D"); list.AddLast("E"); list.AddLast("F"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("Elements in LinkedList..."); foreach (string res in list) { Console.WriteLine(res); } ...

To add elements to the end of the ArrayList, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo { public static void Main(String[] args) { ArrayList list = new ArrayList(); list.Add("Andy"); list.Add("Gary"); list.Add("Katie"); list.Add("Amy"); Console.WriteLine("Elements in ArrayList..."); foreach (string res in list) { Console.WriteLine(res); } string[] strArr = { "John", "Jacob" }; list.AddRange(strArr); Console.WriteLine("Elements in ArrayList...UPDATED"); ...

To add an element to the List, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main(String[] args) { List list = new List(); list.Add("One"); list.Add("Two"); list.Add("Three"); list.Add("Four"); list.Add("Five"); list.Add("Six"); list.Add("Seven"); list.Add("Eight"); Console.WriteLine("Enumerator iterates through the list elements..."); List.Enumerator demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; ...

To check if SortedDictionary contains the specified key or not, the code is as follows −Example Live Demousing System; using System.Collections; using System.Collections.Generic; public class Demo { public static void Main() { SortedDictionary sortedDict = new SortedDictionary(); sortedDict.Add(100, "Mobile"); sortedDict.Add(200, "Laptop"); sortedDict.Add(300, "Desktop"); sortedDict.Add(400, "Speakers"); sortedDict.Add(500, "Headphone"); sortedDict.Add(600, "Earphone"); Console.WriteLine("SortedDictionary key-value pairs..."); IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator(); while (demoEnum.MoveNext()) Console.WriteLine("Key = " + demoEnum.Key + ", Value = ...
