How to convert JSON object to bean using JSON-lib API in Java?

public static Object toBean(JSONObject jsonObject, Class beanClass)

import net.sf.json.JSONObject; public class ConvertJSONObjToBeanTest { public static void main(String[] args) { mployee emp = new Employee("Sai", "Ram", 30, "Bangalore"); JSONObject jsonObj = JSONObject.fromObject(emp); System.out.println(jsonObj.toString(3)); // pretty print JSON emp = (Employee)JSONObject.toBean(jsonObj, Employee.class); System.out.println(emp.toString()); }  // Employee class public static class Employee { private String firstName, lastName, address; private int age; public Employee() { } public Employee(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 "Employee[ " + "firstName = " + firstName + ", lastName = " + lastName + ", age = " + age + ", address = " + address + " ]"; } } }

{ "firstName": "Sai", "lastName": "Ram", "address": "Bangalore", "age": 30 } Employee[ firstName = Sai, lastName = Ram, age = 30, address = Bangalore ]
