我在java中执行一个从表中选择的查询后收到一个异常。该查询在mySQL中正常运行，但当它在java中使用时，我会得到一个异常。我试图在mySQL中运行完全相同的查询，它运行良好，但它会在java中给予一个异常。

public static void main(String[] args) throws SQLException,ClassNotFoundException {
        try {
            Class.forName("com.mysql.cj.jdbc.Driver");
            Connection Con = DriverManager.getConnection("jdbc:mysql://localhost:3306/eldenringbuildgenerator" , "root", "admin");
            Statement teststmt = Con.createStatement();
            ResultSet rs = teststmt.executeQuery("select * ;"); // test query to make sure connection is real
            rs = teststmt.executeQuery("select ArmorTypeID,ArmorTypeName from armortypes;");
            // will delete later
            while (rs.next()) {
                System.out.print(rs.getInt(1) + " " + rs.getString(2) + " " );
            }
        } catch (SQLException e){
            System.out.print(e);
        }
