PreparedStatement with list of parameters in a IN clause [duplicate]

Answer 1

Using Java 8 APIs, 

    List empNoList = Arrays.asList(1234, 7678, 2432, 9756556, 3354646);

    List parameters = new ArrayList<>();
    empNoList.forEach(empNo -> parameters.add("?"));   //Use forEach to add required no. of '?'
    String commaSepParameters = String.join(",", parameters); //Use String to join '?' with ','

StringBuilder selectQuery = new StringBuilder().append("SELECT COUNT(EMP_ID) FROM EMPLOYEE WHERE EMP_ID IN (").append(commaSepParameters).append(")");
