After many searches I found the following way from which you can get all the details.

Following link shows How to Open your app notification channel setting programmatically.

open app notification setting

This may help someone.

Following code will return you all channels of application

public static List<NotificationChannel> getNotificationChannels(Context context) {
    if (isNotificationChannelSupported(context)) {
        NotificationManager notificationManager =
                (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        if (notificationManager == null) {
            Log.e("", "Notification manager is null");
            return null;
        }
        return notificationManager.getNotificationChannels();
    }
    return null;
}

public static boolean isNotificationChannelSupported(Context context) {
    return Build.VERSION.SDK_INT >= 26 && getTargetSdkVersion(context) >= 26;
}

private static int getTargetSdkVersion(Context context) {
    int targetSdk = -1;
    if (context != null) {
        targetSdk = context.getApplicationInfo().targetSdkVersion;
    }
    return targetSdk;
}

Following line will return you sound Uri same way you can get name,Id etc. get(2) is channel you want to refer to retrieve details you can use 0,1 also

Uri soundUri= getNotificationChannels(this).get(2).getSound()
