It is caused due to below one

Caused by: java.sql.SQLSyntaxErrorException: Table 'springdb.departement' doesn't exist

my classes are departement and university

this is the department class.

@Entity
@Table(name = "Departement")
public class Departement {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int idDepart;
    
    private String nomDepart;

    public int getIdDepart() {
        return idDepart;
    }
    
    @ManyToOne
    @JoinColumn(name = "idUniv", nullable = false)
    private Universite universite;

and this is the university class.

@Entity
@Table(name = "Universite")
public class Universite {
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int idUniv;
    
    private String nomUniv;
    
    @OneToMany(mappedBy = "universite")
    private Set<Departement> departements;
