Convert Mobile Ads method to a Lambda expression. How could I do that?

Question

First of all, my code is working, so this is more like a "best practice" kind of question.

I am working with Mobile Ads SDK, using the following code with MobileAds.initialize method:

import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

public class MainActivity extends AppCompatActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });
    }
}

Android Studio is giving me the following warning:

Anonymous new OnInitializationCompleteListener() can be replaced with lambda

I checked out about lambda expressions here.

But I am not sure how, if I should do this conversion, and what would be the benefits of it (just more readability?)

If someone could enlight me I will be thankful.

Basically to solve Warnings in android developing and If you are using Android Studio you can solve those mistakes pretty easily by Ide itself!

Like you are getting warning -

Anonymous new OnInitializationCompleteListener() can be replaced with lambda

you can easily solve by pressing alt + enter or clicking a light bulb and then you will get lot of option to fix those warnings

In your problem you can convert it like this -

MobileAds.initialize(this, initializationStatus -> { 
   // your code here 
});

for example you can see this image by Light Bulb or Alt + Enter while putting cursor in the grey code line.
