How to write this query using JPA Criteria query?

Question

Can anyone help me to get the JPA criteria query for the JPA query mentioned below.

SELECT p,l FROM Person p 
LEFT JOIN Language l ON (p.language = l.language and l.locale like :locale) 
AND p.name like :name 
AND p.time BETWEEN :startDate 
AND :endDate order by name asc

Although the answer given by johncarl was accepted it doesn't look correct to me. The JavaDocs for CriteriaQuery.where() say:

Modify the query to restrict the query result according to the specified boolean expression. Replaces the previously added restriction(s), if any.

As I understand it, each of the following lines (giving restrictions) will override the restrictions given previously:

criteria.where(builder.like(langJoin.get(Language_.locale), locale));
criteria.where(builder.like(pRoot.get(Person_.name), name));
criteria.where(builder.between(pRoot.get(Person_.time), startDate, endDate));

This means that in the end only the last restriction (between start and end date) would remain.

I threfore suggest following modifications to johncarl's answer:

CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Person> criteria = builder.createCriteria(Person.class);
Root<Person> pRoot = criteria.from(Person.class);
Join<Person, Language> langJoin = criteria.join("language", JoinType.LEFT);

Predicate[] restrictions = new Predicate[] { 
    builder.like(langJoin.get(Language_.locale), locale),
    builder.like(pRoot.get(Person_.name), name),
    builder.between(pRoot.get(Person_.time), startDate, endDate)
};

criteria.where(builder.and(restrictions));

criteria.orderBy(builder.asc(pRoot.get(Person_.name)));

However, this code looks really ugly! Please, feel free to edit if it's wrong and comment it if you see a better solution! I'd be gracefull!
