String insert ="insert friends(id,name) values (?,?)";
PreparedStatement prestatement=con.prepareStatement(insert);
String[] names={"liu","qian","shi","xu","zhou","lu"};
for(int i=0;i<6;i++)
{
prestatement.setInt(1, i);
prestatement.setString(2, names[i]);
prestatement.execute();
}
String query="select * from friends";
ResultSet result=(ResultSet) prestatement.executeQuery(query);
while(result.next())
{
System.out.println(result.getString("name"));
}
}
catch (ClassNotFoundException e)
{
e.printStackTrace();
}
catch (SQLException e)
{
e.printStackTrace();
}

}

这是我的程序
已经加载了mysql-connector-java-5.0.6-bin.jar和mysql-connector-java-5.0.6-bin-g.jar包
但总是出现
java.lang.ClassNotFoundException: com.mysql.jdbc.driver
