This error message indicates that you are trying to call a method called `convertToFahrenheit(float)` on an object of the `CelsiusDisplay` class, but such a method is not defined within the class.
To resolve this issue, you need to define the `convertToFahrenheit(float)` method within the `CelsiusDisplay` class. Here's an example implementation:
```
public class CelsiusDisplay {
private float temperature;
// Constructor
public CelsiusDisplay(float initialTemp) {
temperature = initialTemp;
}
// Method to convert temperature to Fahrenheit
public float convertToFahrenheit(float celsiusTemp) {
return (celsiusTemp * 9/5) + 32;
}
// Other methods...
}
```
In this example, we define a `convertToFahrenheit(float)` method that takes a Celsius temperature as input and returns the equivalent temperature in Fahrenheit. We can then call this method on an object of the `CelsiusDisplay` class like this:
```
CelsiusDisplay celsiusDisplay = new CelsiusDisplay(25.0f);
float fahrenheitTemp = celsiusDisplay.convertToFahrenheit(celsiusDisplay.temperature);
System.out.println("Temperature in Fahrenheit: " + fahrenheitTemp);
```
This would output "Temperature in Fahrenheit: 77.0" for an initial Celsius temperature of 25 degrees.
