Le Flexjson est une bibliothèque légère pour sérialiser et désérialiser des objets Java vers et depuis le format JSON. Nous pouvons également sérialiser un tableau d'objets en utilisant la méthode serialize() de la classe JSONSerializer , cela effectue une sérialisation superficielle de l'instance cible.
public String serialize(Object target)
Dans le programme ci-dessous, nous devons sérialiser un tableau d'objets. objets.
import flexjson.JSONSerializer; public class JsonSerializeArrayTest { public static void main(String[] args) { JSONSerializer serializer = new JSONSerializer().prettyPrint(true); Student stud1 = new Student("Adithya", "Sai", 28, "Hyderabad"); Student stud2 = new Student("Jai", "Dev", 30, "Chennai"); Student stud3 = new Student("Ravi", "Chandra", 35, "Pune"); Student[] students = {stud1, stud2, stud3}; String jsonStr = serializer.serialize(students); System.out.println(jsonStr); } } // Student class<strong> </strong>class Student { private String firstName; private String lastName; private int age; private String address; public Student() {} public Student(String firstName, String lastName, int age, String address) { super(); this.firstName = firstName; this.lastName = lastName; this.age = age; this.address = address; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public int getAge() { return age; } public String getAddress() { return address; } public String toString() { return "Student[ " + "firstName = " + firstName + ", lastName = " + lastName + ", age = " + age + ", address = " + address + " ]"; } }
[ { "address": "Hyderabad", "age": 28, "class": "Student", "firstName": "Adithya", "lastName": "Sai" }, { "address": "Chennai", "age": 30, "class": "Student", "firstName": "Jai", "lastName": "Dev" }, { "address": "Pune", "age": 35, "class": "Student", "firstName": "Ravi", "lastName": "Chandra" } ]
