    Exclamation Java Databases error Exception in thread "main" java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?, ?, ?, ?, ?, ?, ?, ?,

    note: I use mysql database if that's of relevance

    Here's the code:
    Can I know how to fix the error

    package databaseTest;

    // import package
    import java.sql.*;
    public class DemoClass {

    public static void main(String[] args) throws Exception {
    // TODO Auto-generated method stub

    // load package from properties then add mysql jar drive
    String url = "jdbc:mysql://localhost:3306/coursesdatabase";
    String uname = "root";
    String pass = "fatima2002";

    String query = "select * from courseslist";
    // register driver
    Class.forName("com.mysql.cj.jdbc.Driver");
    // establish the connect
    Connection con = DriverManager.getConnection(url, uname, pass);
    // create statement
    Statement st = con.createStatement();

    // execute query
    ResultSet rs = st.executeQuery(query);

    String userData=null;

    while(rs.next()) { // how to fetch the whole table
    // shift pointer to next result
    userData = rs.getInt(1) + " : " + rs.getString(2);

    // process results
    System.out.println(userData);
    }

    String query2 = "insert into courseslist values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
    int count = st.executeUpdate(query2); // affects a row
    System.out.println(count + "row/s affected");

    int classcode = 24590;
    String courseCode = "GENS";
    String courseName = "Arabic Language";
    int crdhrs = 3;
    int sectionNum = 1;
    String days = "TRU";
    String time = "11:00-11:50";
    String instructor = "Hakim Ajhar";
    int capacity = 40;
    String SemSrtEnd = "28/08-20/12";
    String roomNum = "G098549";

    PreparedStatement pSt = con.prepareStatement(query2);
    pSt.setInt(1, classcode);
    pSt.setString(2, courseName);
    pSt.setString(3, courseCode);
    pSt.setInt(4, crdhrs);
    pSt.setInt(5, sectionNum);
    pSt.setString(6, days);
    pSt.setString(7, time);
    pSt.setString(8, instructor);
    pSt.setInt(9, capacity);
    pSt.setInt(10, 0);
    pSt.setInt(11, 0);
    pSt.setString(12, SemSrtEnd);
    pSt.setString(13, roomNum);

    int count2 = pSt.executeUpdate();
    System.out.println(count2 + "row/s affected");
    // close
    st.close();
    con.close();

    }

    }
