using array in JPQL query

Question

How can I use an array list in JPQL query? I want something like this: I am passing this

private static final String[] MASKS = {"30109", "30111"};

into

public List<Account> findAccount(String[] Masks){
StringBuilder sb = new StringBuilder("from AccountTable a where SUBSTRING(a.Account,1,5) in :Masks ");
Query q = em.createQuery(sb.toString(), AccountTable.class)
                .setParameter("Masks",Masks);
}

currently, error is

Encountered array-valued parameter binding, but was expecting [java.lang.String (n/a)]; nested exception is java.lang.IllegalArgumentException: Encountered array-valued parameter binding, but was expecting [java.lang.String (n/a)]

Reading this site it seems that is possible, but your array must be a Collection , maybe something like this:

public List<Account> findAccount(String[] Masks){
    StringBuilder sb = new StringBuilder("from AccountTable a where SUBSTRING(a.Account,1,5) in :Masks ");
    Query q = em.createQuery(sb.toString(), AccountTable.class)
                .setParameter("Masks", Arrays.asList(MASKS));
}

Should help you.
