The best replacement for static final

1

in Java we use something like

@NamedQuery(name = Entity.FIND_BY_NAME,
  query = “select o from Entity o where o.name = ?1”)
public class Entity {
  public static final String FIND_BY_NAME = “Entity.byName”;

  public static Query findByName(EntityManager em, String name) {
  return em.createNamedQuery(FIND_BY_NAME).setParameter(1, name);
  }
}

but in Kotlin I can’t find appropriate way to replace such kind of constants:
package level values may cause naming conflicts.

This should work: 

@NamedQuery(name = Entity.FIND_BY_NAME,
            query = "select o from Entity o where o.name = ?1")
public class Entity {
    companion object {
        public val FIND_BY_NAME: String = "Entity.byName"

    public fun findByName(em: EntityManager,



                              name: String): Query {

            return em.createNamedQuery(FIND_BY_NAME).setParameter(1, name)

  }

  }

}


If your Java class had only static fields and methods you could write:

@NamedQuery(name = Entity.FIND_BY_NAME,
            query = "select o from Entity o where o.name = ?1")
public object Entity {
    public val FIND_BY_NAME: String = "Entity.byName"



  public fun findByName(em: EntityManager,

                          name: String): Query {

  return em.createNamedQuery(FIND_BY_NAME).setParameter(1, name)

  }

}
