Java for loop printing only 1st value- BuilderPattern - object

Question

I am trying to experiment and learn BuilderPattern,reading from json file at the same time. My goal is to create object using the data I get from the json file. This is how the json file looks like:
[{
"firstName": "Git",
"lastName": "Hub",
"website": "howtodoinjava.com"
},
{
"firstName": "Brian",
"lastName": "Schultz"
}
]
Class1: Employee Class
public class Employee {
private String firstName; // required
private String lastName; // required
private String website; // optional
//Only has setters
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public void setWebsite(String website) {
this.website = website;
}
//no public constructor. So the only way to get a Employee object is through the EmployeeBuilder class.
private Employee(EmployeeBuilder builder) {
this.firstName = firstName;
this.lastName = lastName;
this.website = website;
}
public static class EmployeeBuilder {
private String firstName; // required
private String lastName; // required
private String website; // optional
public EmployeeBuilder() throws IOException {
}
public EmployeeBuilder requiredFirstName(String firstName) {
this.firstName = firstName;
return this;
}
public EmployeeBuilder requiredLastName(String lastName) {
this.lastName = lastName;
return this;
}
public EmployeeBuilder optionalWebsite(String website) {
this.website = website;
return this;
}
//Return the finally constructed User object
public Employee build() {
Employee emp = new Employee(this);
return emp;
}
}
}
Class2: User Class
public class User {
String firstName;
String lastName;
String website;
//Using Getters to get values from Json
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String getWebsite() {
return website;
}
}
3 Main class
public class Main {
public static void main(String[] args) throws IOException {
ObjectMapper object = new ObjectMapper();
User[] user = object.readValue(new File("C:\\MyTemp\\jackson.json"), User[].class);
//Employee employee= new Employee.EmployeeBuilder().requiredFirstName(person.getFirstName()).requiredLastName(person.getLastName()).optionalWebsite(person.getWebsite()).build();
List<User> emp1 = object.readValue("C:\\MyTemp\\jackson.json", new TypeReference<List<User>>() {});
emp1.stream().forEach(x -> System.out.println(x));
/*for (User person : user) {
Employee employee= new Employee.EmployeeBuilder().requiredFirstName(person.getFirstName()).build();
System.out.println(employee);
} */
}
}
Problem: When I run this code all I get are the 1st names. Git and Brian. I am not getting the last names or website.
Can someone please suggest what am I missing? Thanks in advance for your time.
