Javaでflexjsonを使用してオブジェクトの配列をシリアル化するにはどうすればよいですか？

public String serialize(Object target)

以下のプログラムでは、オブジェクトの配列をシリアル化する必要があります。

例

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
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 +
      " ]";
   }
}

出力

[
 {
 "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"
 }
