In this section, you will learn to use the "and" method. This is one of the most important method that returns the conjunctions of two expressions. You can also build the nested expressions using 'and' and 'or'. Expressions: The Hibernate Criteria API supports a rich set of comparison operators. Some standard SQL operators are =, <, ?, >, ?.
Expression and(Criterion LHS, Criterion RHS): This method returns the conjunctions of two expressions. Both conditions are 'true' then it xecutes the query otherwise not. In this tutorial, "and" is used :
Expression.and(Expression.gt("lngInsuranceId", new Long(3), Expression.lt("IngInsuranceId", new Long(6))).
