## JSON Serialization with Java Reflection API
### Features
* _@JsonSerializable_ - Class annotation to mark class as json serializable
* _@JsonElement_ - Field annotation to mark field as json serializable. Can have an alias and can be marked as required (only for Objects)
* _@JsonInit_ - Method annotation. The method will execute before the json is constructed
### Can serialize
* primitives and wrapper classes
* arrays
* collections (lists, sets)
* objects
* maps
### Example
```java
@JsonSerializable
public class Student {
@JsonElement
private String firstName;
@JsonElement
private String lastName;
@JsonElement(required = false)
private String middleName;
public Student(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
}
```
```java
Student student = new Student("John", "Doe");
String jsonString = JsonConverter.convertToJson(student);
System.out.println(jsonString);
```
Output
```json
{"firstName": "John", "lastName": "Doe"}
```
