In Java, Jackson is a library that is used to convert JSON to Java objects and vice versa. Jackson Annotations are used during serialization and deserialization to denote a particular field that is declared in Java as an instance variable, is a JsonProperty, and should be ignored. We can also use annotations with methods. So, basically, Annotations make JSON output clearer as we required. In this Article, we will learn about one of its annotations is @JsonRawValue Annotation. @JsonRawValue This annotation can be used for methods and fields. The @JsonRawValue annotation is used to serialize methods or fields as it ... Read More

The Uri.FromHex() method in C# is used to get the decimal value of a hexadecimal digit.SyntaxFollowing is the syntax −public static int FromHex (char digit);Above, the parameter digit is the hexadecimal digit (0-9, a-f, A-F) to convert.ExampleLet us now see an example to implement the Uri.FromHex() method −using System; public class Demo {    public static void Main(){       char ch = 'D';       Console.WriteLine("Character value = "+ch);       int res = Uri.FromHex(ch);       Console.WriteLine("Converted int value = "+res);    } }OutputThis will produce the following output −Character value = D Result ...
