How to Convert JSON Array Object to Java Object?

package org.example;

public class User 
{
    private String firstName;
    private String lastName;

    private String email;

    public User() {}
    // Constructor Declaration
    public User(String firstName, String lastName,
                String email)
    {
        this.firstName = firstName;
        this.lastName = lastName;
        this.email = email;
    }
    // generate getters and setters
    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 String getEmail() 
    { 
      return email; 
    }

    public void setEmail(String email)
    {
        this.email = email;
    }
}

package org.example;

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args)
    {
        try {
            // JSON string representing an array of user objects
            String jsonString = "[{\"firstName\":\"User1\",\"lastName\":\"XYZ\",\"email\":\"[email protected]\"},"
                  + "{\"firstName\":\"User2\",\"lastName\":\"PQR\",\"email\":\"[email protected]\"}]";

            // Create an ObjectMapper instance
            ObjectMapper objectMapper = new ObjectMapper();

            // Deserialize the JSON string into an array of User objects
            User[] users = objectMapper.readValue(jsonString, User[].class);

            // Print the details of each user
            for (User user : users) {
                System.out.println(
                    "First Name: " + user.getFirstName()
                    + ", Last Name: " + user.getLastName()
                    + ", Email: " + user.getEmail());
            }
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}
