POJO

Plain Old java object (not Bean)

Example

public class EmployeePOJO {

    private String firstName;
    private String lastName;
    private LocalDate startDate;

    public EmployeePOJO(String firstName, String lastName, LocalDate startDate) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.startDate = startDate;
    }

    public String name() {
        return this.firstName + " " + this.lastName;
    }

    public LocalDate getStart() {
        return this.startDate;
    }
}

It's not JavaBean because:

1. It does not implement serializable class
2. There is no Setter for private
3. Getter convention name is wrong
