How to Add Filter in DynamoDB Query with Number Set using Java SDK/PartiQL?

In the PartiQL query editor the queries would look like:

SELECT * FROM "tablename" WHERE contains("field1", 2)

SELECT * FROM "tablename" WHERE contains("field1", 3)

I have never created any JAVA client but reading the docs it would be someting like

statement = new ParameterizedStatement()
     .withStatement("SELECT * FROM 'tablename' WHERE contains('field1', ?)")
     .withParameters(new AttributeValue(2))
