Getting null values with data in list of collection of object

I am trying to add few employee objects inside the list named collectionofEmployees here.I am able to add the data but i am getting first record for custom object attributes as nulls.The data is getting inserted after that properly.

Here is my controller.

@RestController
public class CustomController {

@Autowired
Employees collectionofEmployees;

@RequestMapping("/add")
public Employees add() {
    
    collectionofEmployees.add(new Employee(1,"XYZ"));
    collectionofEmployees.add(new Employee(3, "VTY"));
    return collectionofEmployees;

}

Here is my Employees Model class which contains list of employee

@Component
public class Employees {

@Autowired
private List<Employee>employees;

public List<Employee> getEmployees() {
    return employees;
}
public Employees(List<Employee> employees) {
    super();
    this.employees = employees;
}


public void setEmployees(List<Employee> employees) {
    this.employees = employees;
}


public void add(Employee employee)
{        
         this.employees.add(employee);
    
}

Here is my employee class

@Component
public class Employee {

private Integer id;
private String name;
public Integer getId() {
    return id;
}   
public Employee() {
    super();
}


public Employee(Integer id, String name) {
    super();
    this.id = id;
    this.name = name;
}


public void setId(Integer id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}

The output i am getting is as {"employees":[{"id":null,"name":null},{"id":1,"name":"XYZ"},{"id":3,"name":"VTY"}]}

Help would be appreciated alot:)I want to avoid nulls

As i still dont know how to avoid nulls at time of intialisation done by spring,for temporary purpose i have added collectionofEmployees.getEmployees().remove(0) under add method which removes the nulls from the input.

Try to remove @Component from Employee class. It is initialized by Spring and injected to your

@Autowired
private List<Employee>employees
