The Uri.Equals() method in C# compares two Uri instances for equality.SyntaxFollowing is the syntax −public override bool Equals (object comparand);Above, the parameter comparand is the Uri instance or a URI identifier to compare with the current instance.ExampleLet us now see an example to implement the Uri.Equals() method −using System; public class Demo {    public static void Main(){       Uri newURI1 = new Uri("https://www.tutorialspoint.com/index.htm");       Console.WriteLine("URI = "+newURI1);       Uri newURI2 = new Uri("https://www.tutorialspoint.com/index.htm");       Console.WriteLine("URI = "+newURI2);       if(newURI1.Equals(newURI2))          Console.WriteLine("Both the URIs are equal!");   ...

The Uri.CheckHostName() method in C# is used to determine whether the specified hostname is a valid DNS name.SyntaxFollowing is the syntax −public static UriHostNameType CheckHostName (string host_name);ExampleLet us now see an example to implement the Uri.CheckHostName() method −using System; public class Demo {    public static void Main(){       string strURI = "http://localhost";       Console.WriteLine("URI = "+strURI);       UriHostNameType res = Uri.CheckHostName(strURI);       Console.WriteLine("Host type = "+res);    } }OutputThis will produce the following output −URI = http://localhost Host type = UnknownExampleLet us now see another example to implement the Uri.CheckHostName() method ...

The UInt64.ToString() method in C# is used to convert the numeric value of the current UInt64 instance to its equivalent string representation.SyntaxFollowing is the syntax −public override string ToString();ExampleLet us now see an example to implement the UInt64.ToString() method −using System; public class Demo {    public static void Main(){       ulong val1 = 465656665;       ulong val2 = 232525678;       Console.WriteLine("Value1 (String representation) = "+val1.ToString());       Console.WriteLine("Value2 (String representation) = "+val2.ToString());       bool res = val1.Equals(val2);       Console.WriteLine("Return value (comparison) = "+res);       if (res) ...

The closest() method in jQuery is used to return the first ancestor of the selected element.SyntaxThe syntax is as follows −$(selector).closest(filter)ExampleLet us now see an example to implement the jQuery closest() method −    .demo * {       display: block;       border: 2px solid blue;       padding: 5px;       margin: 15px;    }    $(document).ready(function(){       $("span").closest("ol").css({"background-color": "orange", "color": "black","border": "3px dashed orange"});    }); body ol ol ol li span OutputThis will produce the following output −

The fadeIn() method in jQuery is used to change the opacity, for selected elements, from hidden to visible.SyntaxThe syntax is as follows −$(selector).fadeIn(speed, easing, callback)ExampleAbove, speed is the speed of the fading effect. The easing can be swing or linear for speed at different animation points. Callback is the function to be executed after the method gets finished.Let us now see an example to implement the jQuery fadeIn() method −    $(document).ready(function(){       $(".btnout").click(function(){          $("div").fadeOut();       });       $(".btnin").click(function(){          $("div").fadeIn();     ...

The @JsonIdentityInfo annotation is used when an object has a parent-child relationship in the Jackson library. The @JsonIdentityInfo annotation is used to indicate the object identity during the serialization and deserialization process. The ObjectIdGenerators.PropertyGenerator is an abstract place-holder class to denote a case where Object Identifier to use comes from a POJO property.Syntax@Target(value={ANNOTATION_TYPE, TYPE, FIELD, METHOD, PARAMETER}) @Retention(value=RUNTIME) public @interface JsonIdentityInfoExampleimport java.util.*; import java.io.*; import com.fasterxml.jackson.annotation.JsonIdentityInfo; import com.fasterxml.jackson.annotation.ObjectIdGenerators; import com.fasterxml.jackson.databind.ObjectMapper; public class JsonIdentityInfoTest {    public static void main(String[] args) throws IOException {       ObjectMapper mapper = new ObjectMapper();       User user = new User(115, "Raja", "Ramesh");       ...
