Java code example (using the StringUtils utility class for string processing):
import android.support.coreutils.StringUtils;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String originalString = "Hello World";
String transformedString = StringUtils.capitalize(originalString);
Log.d("MainActivity", "Transformed String: " + transformedString);
}
}
In the above example, we imported the StringUtils utility class and used its capitalize() method to capitalize the first character of the original string. Finally, we print the converted string to LogCat.
