I have a Spring boot project wich store data in database.
I want to get it by sorting dby date desc.

This is example of code :
//Furit family entity store in database
@Entity(name = “FruitFamily”)
public class FruitFamilyEntity {

  @Column(name = "user_id", nullable = false)
  private String userId;

  @Column(name = "fruitfamily_id", updatable = false, nullable = false)
  private UUID fruitFamilyId;

  @Enumerated(EnumType.STRING)
  @Column(name = "typeFruit", updatable = false, nullable = false)
  private TypeFruit typeFruit;

  @Column(name = "purchase_date")
  private LocalDateTime purchaseDate;

  @Override
  public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || Hibernate.getClass(this) != Hibernate.getClass(o)) return false;
    LifestyleEntity that = (LifestyleEntity) o;
    return getId() != null && Objects.equals(getId(), that.getId());
  }

  @Override
  public int hashCode() {
    return getClass().hashCode();
  }
}

@Getter
@AllArgsConstructor
public enum TypeFruit {
  STONE_FRUIT("Fruit à noyau"),
  POME_FRUIT("Fruit à pepin"));

  private final String display;
}

@Getter
@Setter()
@NoArgsConstructor
@AllArgsConstructor
public class FruitFamily {

  private String userId;

  private UUID fruitFamilyId;
  
  private TypeFruit typeFruit;

  private LocalDateTime purchaseDate;
}

public class FruitStore {

    public Map<TypeFruit, List<FruitFamily>> allFruitFamily() {
    
        FruitFamily fruit1 = new FruitFamily("1","8244f3ca-1881-44e3",STONE_FRUIT,LocalDateTime.parse("2024-05-02T16:15:54.332"))
        FruitFamily fruit2 = new FruitFamily("2","8244f3ca-1880-45e3",STONE_FRUIT,LocalDateTime.parse("2024-05-01T18:34:28.127"))
        FruitFamily fruit3 = new FruitFamily("3","8244f3ca-1882-46e3",STONE_FRUIT,LocalDateTime.parse("2024-01-28T10:04:28.187"))
        FruitFamily fruit4 = new FruitFamily("4","8244f3ca-1883-47e3",STONE_FRUIT,LocalDateTime.parse("2023-07-18T22:20:45.332"))
        FruitFamily fruit5 = new FruitFamily("5","8244f3ca-1879-48e3",POME_FRUIT,LocalDateTime.parse("2023-05-01T22:20:45.332"))
        FruitFamily fruit6 = new FruitFamily("6","8244f3ca-18767-49e3",POME_FRUIT,LocalDateTime.parse("2023-05-02T12:35:26.443"))
        FruitFamily fruit7 = new FruitFamily("7","8244f3ca-1841-42e3",POME_FRUIT,LocalDateTime.parse("2023-09-13T14:50:26.332"))
        FruitFamily fruit8 = new FruitFamily("8","8244f3ca-1823-41e3",POME_FRUIT,LocalDateTime.parse("2024-05-02T15:23:45.332"))
        
        FruitFamily arrFruit[] = {fruit1,fruit2,fruit3,fruit4,fruit5,fruit6,fruit7,fruit8};
        
        var listFruitFamily = Arrays.asList(arrFruit);
        
        EnumMap<TypeFruit, List<FruitFamily>> result = new EnumMap<>(TypeFruit.class);

        listFruitFamily.forEach(fruitFam -> {
            var listByTypeFruit = result.computeIfAbsent(fruitFam.getTypeFruit(), k -> new ArrayList<>());
            listByTypeFruit.add(fruitFam);
        });

        return result;
    }

    public static void main(String[] args)
    {
        
        
    }

}

I want to filter my result by most recent purchase date by type of fruit

[STONE_FRUIT : 
  [
   {"userId":"1","fruitFamilyId":"8244f3ca-1881-44e3","userId":STONE_FRUIT,"purchaseDate":"2024-05-02T16:15:54.332"},
   {"userId":"2","fruitFamilyId":"8244f3ca-1881-44e3","userId":STONE_FRUIT,"purchaseDate":"2024-05-01T18:34:28.127"},
   {"userId":"3","fruitFamilyId":"8244f3ca-1881-44e3","userId":STONE_FRUIT,"purchaseDate":"2024-01-28T10:04:28.187"},
   {"userId":"4","fruitFamilyId":"8244f3ca-1881-44e3","userId":STONE_FRUIT,"purchaseDate":"2023-07-18T22:20:45.332"}
   ]
],

[POME_FRUIT : 
  [
   {"userId":"8","fruitFamilyId":"8244f3ca-1881-44e3","userId":POME_FRUIT,"purchaseDate":"2024-05-02T15:23:45.332"},
   {"userId":"7","fruitFamilyId":"8244f3ca-1881-44e3","userId":POME_FRUIT,"purchaseDate":"2023-09-13T14:50:26.3323"},
   {"userId":"6","fruitFamilyId":"8244f3ca-1881-44e3","userId":POME_FRUIT,"purchaseDate":"2023-05-02T12:35:26.443"},
   {"userId":"5","fruitFamilyId":"8244f3ca-1881-44e3","userId":POME_FRUIT,"purchaseDate":"2023-05-01T22:20:45.332"}
   ]
]

My allFruitFamily function does not filter by purchase date desc. how to get the result above
