Example Code

Here is an example of how to use super.onCreate in an Android activity:
java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialize variables and data structures
// Bind views to data
// Set up event listeners
}
}
In this example, super.onCreate is called before performing any other initialization tasks in the onCreate method.
