. Kami juga boleh mensirikan tatasusunan objek menggunakan kaedah
serialize() kelas
JSONSerializer, ini melakukan siri cetek bagi contoh sasaran.
Syntax
public String serialize(Object target)Dalam atur cara di bawah, kita perlu mensirikan tatasusunan objek.Contoh
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 + " ]"; } }输出
[ { "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" } ]
