This is a sample code but very similar to my code.

class JW_Options{
    public $options;

    public function __construct(){
        //delete_option('jw_plugin_options');
        $this->options = get_option('jw_plugin_options');
        $this->register_setting_and_fields();  

    }

    public static function add_menu_page(){
        add_options_page('Theme Options', 'Theme Options', 'administrator', __FILE__, array('JW_Options', 'display_options_page'));
    }

    public static function display_options_page(){
        ?>
        <div class="wrap">
            <?php screen_icon(); ?>
            <h2>My Theme Options</h2>
            <?php print_r(get_option('jw_plugin_options'));?>
            <form method="post" action="options.php" enctype="multipart/form-data">
                <?php settings_fields('jw_plugin_options'); ?>
                <?php do_settings_sections(__FILE__); ?>

                <P class="submit">
                    <input name="submit" type="submit" class="button-primary" value="Save Changes" />

                </P>
            </form>

        </div>

        <?php
    }

    public function register_setting_and_fields(){
        register_setting('jw_plugin_options', 'jw_plugin_options', array($this, 'jw_validate_settings'));// 3rd param = optional call back function
        //register_setting('jw_plugin_options', 'jw_plugin_options');
        add_settings_section('jw_main_section', 'Main Settings', array($this, 'jw_main_section_cb'), __FILE__); // id,title of section, cb, which page?
        add_settings_field('jw_banner_heading', 'Banner Heading', array($this, 'jw_banner_heading_setting'), __FILE__, 'jw_main_section');
        add_settings_field('jw_logo', 'Your Logo', array($this, 'jw_logo_setting'), __FILE__, 'jw_main_section');
        add_settings_field('jw_color_scheme', 'Your Desired Color Scheme', array($this, 'jw_color_scheme_setting'), __FILE__, 'jw_main_section');
    }

    public function jw_main_section_cb(){
        //optional
    }

    public function jw_validate_settings($plugin_options){
        print_r($plugin_options);
    }

    /*
     *
     *Inputs
     *
     */

    // Banner Heading
    public function jw_banner_heading_setting(){

        echo "<input name='jw_plugin_options[jw_banner_heading]' type='text' value='{$this->options['jw_banner_heading']}' />";
        //echo "<input name='jw_plugin_options[jw_banner_heading]' type='text' value='' />";
    }

    public function jw_logo_setting(){

        echo '<input type= "file" />';
    }

    public function jw_color_scheme_setting(){
        $items = array('Red', 'Green', 'Blue', 'Yellow', 'Black', 'White');
        echo "<select name='jw_plugin_options[jw_color_scheme]'>";
        foreach ($items as $item){
            $selected = ($this->options['jw_color_scheme']== $item) ? 'selected="selected"' : '';
            echo "<option value='$item' $selected>$item</option>";
        }
        echo "</select>";

    }

}

add_action('admin_menu', function(){
    JW_Options::add_menu_page();
});

add_action('admin_init', function(){
    new JW_Options();
});
