Flexjson जावा ऑब्जेक्ट को JSON प्रारूप में सीरियलाइज़ और डिसीरियलाइज़ करने के लिए एक हल्की लाइब्रेरी है। हम JSONDeserializer क्लास की deserialize() विधि का उपयोग करके रीडर स्ट्रीम से जावा ऑब्जेक्ट को डिसीरियलाइज़ कर सकते हैं, यह JSON इनपुट के रूप में Reader क्लास के इंस्टेंस का उपयोग करता है।
सिंटैक्स
public T deserialize(Reader input)
उदाहरण
import java.io.*; import flexjson.JSONDeserializer; public class JSONDeserializeReaderTest { public static void main(String[] args) { JSONDeserializer deserializer = new JSONDeserializer(); String jsonStr = "{" + "\"firstName\": \"Adithya\"," + "\"lastName\": \"Sai\"," + "\"age\": 25," + "\"address\": \"Hyderabad\"" + "\"class\": \"Student\"" + "}"; Student student = deserializer.deserialize(new StringReader(jsonStr)); System.out.println(student); } } // 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 void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public String toString() { return "Student[ " + "firstName = " + firstName + ", lastName = " + lastName + ", age = " + age + ", address = " + address + " ]"; } } आउटपुट
Student[ firstName = Adithya, lastName = Sai, age = 25, address = Hyderabad ]
