How to avoid @SuppressWarnings on generic arrays

Question

I have the following code

ParameterExpression<String>[] searchStrings = new ParameterExpression[10];

Which works but will give a warning stating that I am doing an "unchecked" operation which is the case.

I want to get rid of the warning without doing a @SupressWarnings but if I do

ParameterExpression<String>[] searchStrings = new ParameterExpression<String>[10];

I get an error

Cannot create a generic array of ParameterExpression

Is there anyway to remove the warning without using @SupressWarnings?

Is there any class that is a concrete implementation of ParametersExpression that you will use? — Eddie Martinez, Jul 14 '17 at 15:06

Not without making it specific to the JPA provider http://docs.oracle.com/javaee/6/api/javax/persistence/criteria/ParameterExpression.html — Archimedes Trajano, Jul 14 '17 at 15:07
@ArchimedesTrajano it seems your best is a `List` ¯\_(ツ)_/¯ — Eddie Martinez, Jul 14 '17 at 15:11

With arrays, you cannot initialize using generic classes, but you can do a list

List<ParameterExpression<String>> searchStrings = new ArrayList<>();
