AlertDialog setButton was deprecated

Question

I use this code in my Eclipse Android project

alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
    
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
});

But Eclipse is saying:

This method was deprecated in API level 3. Use setButton(int, CharSequence, android.content.DialogInterface.OnClickListener) with BUTTON_POSITIVE

UPDATE AFTER 5 YEARS

This was my first step on entering a real programming adventure. It was like, oh I know how to do html website and this must be easy to code -native programming- so lets jump into it without reading any document. This is my first question on this awesome community which is a terrible question. One big suggestion that I can give to any beginner programmer which is; have some idea, dig some document and read open source about how others made before you jump into a new adventure. Patiently read the error that you encounter and try to realise what the real problem is. Thus you don't ask unnecessary question.

Java

AlertDialog alert = new AlertDialog.Builder(this).create();
            alert.setTitle("Error");
            alert.setMessage("Sorry, your device doesn't support flash light!");
            alert.setButton(Dialog.BUTTON_POSITIVE,"OK",new DialogInterface.OnClickListener(){

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });

alert.show();

Kotlin

    var alert: AlertDialog = AlertDialog.Builder(this).create()
    alert.setTitle("Error")
    alert.setMessage("Sorry, your device doesn't support flash light!")
    alert.setButton(Dialog.BUTTON_POSITIVE, "OK", DialogInterface.OnClickListener {
            //do your own idea.
            dialog, which -> finish() })
    alert.show()
