My mistake for Channel ID need to create some Channel id just like my past question

I created another class for Channel id

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel1 = new NotificationChannel(
                CHANNEL_1_ID,
                "Channel 1",
                NotificationManager.IMPORTANCE_HIGH
        );
        channel1.setDescription("This is channel 1");

        NotificationChannel channel2 = new NotificationChannel(
                CHANNEL_2_ID,
                "Channel 2",
                NotificationManager.IMPORTANCE_LOW
        );
        channel2.setDescription("This is channel 2");

        NotificationManager manager = getSystemService(NotificationManager.class);
        manager.createNotificationChannel(channel1);
        manager.createNotificationChannel(channel2);
    }
}
