My annotation created with reflection API return null even when there is data

so I'm building ORM Manager from scratch with reflection API, everything works fine but there is one annotation @Table that i created and it doesn't want to work as it should. So annotation looks like this

@Retention(RetentionPolicy.RUNTIME)
  @Target(ElementType.TYPE)
   public @interface Table {
    String value() default "";
}

and I'm using it on my model class as so

@Entity
@Table(value = "Books")
public class Book {

and now i'm trying to get that value passed as a parameter like this

@Override
    void register(Class... entityClasses) throws SQLException {
        for (Class entityClass : entityClasses) {

            if (entityClass.isAnnotationPresent(Entity.class)) {

                String tableName;

                if (entityClass.isAnnotationPresent(Table.class)) {
                    tableName = entityClass.getClass().getDeclaredAnnotation(Table.class).value();
                } else {
                    tableName = entityClass.getSimpleName();
                }

Dont mind @Entity annotation it works fine. Only problem is that @Table annotation always returns null so it throws NullPointerException and crashing.

Where is a problem, how can i solve this. I already implemented @Column annotation and when i use .value() on @Column annotation it works fine so no clue why it doesn't work for @Table
