Estoy tratando de insertar algunos datos en mi base de datos con jdbc. Estoy usando la tabla correcta, el nombre de base de datos y los parámetros. Todo está revisado.

Código

public static void main(String[] args) throws IOException/*, ClassNotFoundException, SQLException*/ {
    DataInputStream d = new DataInputStream(System.in);
    System.out.println("Enter employee ID : ");

    @SuppressWarnings("deprecation")
    int empid = Integer.parseInt(d.readLine());

    System.out.println("Enter employee name : ");

    @SuppressWarnings("deprecation")
    String empname = d.readLine();

    System.out.println("Enter employee ID : ");
    @SuppressWarnings("deprecation")
    double empsalary = Double.parseDouble(d.readLine());

    try {
        Class.forName("com.mysql.jdbc.Driver");

    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    Connection con;
    try {
        con = DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB","root","");
        PreparedStatement  pst = con.prepareStatement("insert into `employee` values(?,?,?");
        pst.setInt(1, empid);
        pst.setString(2, empname);
        pst.setDouble(3, empsalary);
        int rowcount = pst.executeUpdate();
        System.out.println(rowcount + " row has been instered");
    } catch (SQLException e) {

        e.printStackTrace();
    }

y aquí están los errores que me da cuando intento ejecutarlo:
