 Save the java code and run the program.

 Now the output is displayed on the emulator which are created.

SOURCE CODE:

public class ConvertTempertureExample extends Activity { private EditText text;

@Override

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

} else {

private float convertFahrenheitToCelsius(float fahrenheit) { return ((fahrenheit - 32) * 5 / 9);

}

// Converts to fahrenheit

private float convertCelsiusToFahrenheit(float celsius) { return ((celsius * 9) / 5) + 32;
