Employee[] employees = {
    new Employee("Anton", "Pavlov"),
    new Employee("Elena", "Kirienko")
};

class Employee
{
    public String firstName;
    public String lastName;
    
    public Employee(String firstName, String lastName)
    {
        this.firstName = firstName;
        this.lastName = lastName;
