clarification of “this” keyword in Java

Question

I have this code copied from Android developers website:

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCrea         


        

Answer 1

"this" is a reference to the current object.

In your case, it refers to an instance of the ExampleActivity class.
