How the setcontentview is called?

Question

I was tweaking the sample hello world app that android studio provides and found out that I cannot call the setContentView(R.layout.activity_main); outside any method.For example:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    setContentView(R.layout.activity_main); //compilation error
}

I know that I should not be calling setContentView outside onCreate(),but just for a reference I tried it out.I can figure out that this has something to do with Java and not android,but I can't seem to figure out the where the problem exactly lies.Any help will be appreciated.

It needs to be **inside** the `onCreate()` method, not **outside**. — Phantômaxx, Oct 17 '16 at 15:32
The compilation error is because a call to a method has to be inside another method, a static block or used in an expression (for example to initialize a variable). — Xavier Rubio Jansana, Oct 17 '16 at 15:33
It needs to be called inside any method and It will set the content view with no problem. You must read OOP fundamentals. — elmontoya7, Oct 17 '16 at 15:37
Just move the first closing bracket (`}`) **one line down**. Enjoy. — Phantômaxx, Oct 17 '16 at 15:53

As per activity life cycle onCreate() is the method called when the activity is first created

OnCreate() is the point where most initialization should go: calling setContentView(int) to inflate the activity's UI, using findViewById to programmatically interact with widgets in the UI, calling managedQuery(android.net.Uri , String[], String, String[], String) to
