Java Database Connectivity (JDBC)

I have the following:

  Connection conn = null;

  OracleCallableStatement orclCallStmt = null;

  Integer[] ackinfo = new Integer[ack.size()];

               ack.toArray(ackinfo);

  Integer[] nakinfo = new Integer[nak.size()];

               nak.toArray(nakinfo);

   query = "call pm_pbx_systems.updateInfTransport(?,?)";

  oracle.sql.ARRAY ackList;

  oracle.sql.ARRAY nakList;

ArrayDescriptor acks = ArrayDescriptor.createDescriptor( "T_NUMBER_ARRAY", conn);

             ackList = new ARRAY(acks, conn, ackinfo);

  ArrayDescriptor naks = ArrayDescriptor.createDescriptor( "T_NUMBER_ARRAY", conn);

          nakList = new ARRAY(naks, conn, nakinfo);

    orclCallStmt = (OracleCallableStatement) conn.prepareCall(query);

    orclCallStmt.setObject(1, ackList);

   orclCallStmt.setObject(2, nakList);

    orclCallStmt.execute();

CREATE OR REPLACE TYPE   t_number_array AS TABLE OF number;

I am using OJDBC7.jar for Oracle 12C.

I would like not to use a deprecated method.
