# Creando a capa Modelo/Entity

Na capa de modelo imos a crear un conxunto de clases que representan a cada unha das entidades que temos definidas na base de datos. 

No exemplo que se expón a continuación amosase a definición da clase alumno:

```java
package Modelo;

import java.time.LocalDate;

public class Alumno {
    private int id;
    private String nombre;
    private String apellido;
    private LocalDate fechaNac;

    public Alumno() {
    }

    public Alumno(int id, String nombre, String apellido, LocalDate fechaNac) {
        this.id = id;
        this.nombre = nombre;
        this.apellido = apellido;
        this.fechaNac = fechaNac;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getNombre() {
        return nombre;
    }

    public void setNombre(String nombre) {
        this.nombre = nombre;
    }

    public String getApellido() {
        return apellido;
    }

    public void setApellido(String apellido) {
        this.apellido = apellido;
    }

    public LocalDate getFechaNac() {
        return fechaNac;
    }

    public void setFechaNac(LocalDate fechaNac) {
        this.fechaNac = fechaNac;
    }

    @Override
    public String toString() {
        return "Alumno{" +
                "id=" + id +
                ", nombre='" + nombre + '\'' +
                ", apellido='" + apellido + '\'' +
                ", fechaNac=" + fechaNac +
                '}';
    }
}

```
