Question

What is currently the most common way to authenticate users on private and public computer networks?

Answer 1

To create a Thermometer class in programming, you start with an initial temperature of 0°C, increase it by 10°C using setCelsius, and then use the getFahrenheit method to print the equivalent Fahrenheit temperature, which would be 50°F.

Step-by-step explanation:

To address the student's schoolwork question regarding the creation and manipulation of a Thermometer class in programming, we begin by constructing the thermometer with a no-arguments constructor that sets its initial temperature to 0°C. We then use the setCelsius method to increase the temperature by 10 degrees Celsius. Following this, we use the getFahrenheit method to retrieve the current temperature in Fahrenheit and print it.

The conversion between Celsius and Fahrenheit uses the formula: Fahrenheit = (Celsius * 9/5) + 32. Therefore, after raising the temperature by 10°C, we must apply this formula to get the resulting Fahrenheit temperature.

Example Implementation:

public class Thermometer {
private double temperatureCelsius;

public Thermometer() {
this.temperatureCelsius = 0;
}

public void setCelsius(double temperature) {
this.temperatureCelsius = temperature;
}

public void setFahrenheit(double temperature) {
this.temperatureCelsius = (temperature - 32) * 5/9;
}

public double getCelsius() {
return this.temperatureCelsius;
}

public double getFahrenheit() {
return (this.temperatureCelsius * 9/5) + 32;
}

public static void main(String[] args) {
Thermometer myThermometer = new Thermometer();
myThermometer.setCelsius(myThermometer.getCelsius() + 10);
System.out.println("The temperature in Fahrenheit is: " + myThermometer.getFahrenheit());
}
}

In this example, the Thermometer starts at 0°C, then we add 10°C to make it 10°C, which is equivalent to 50°F after conversion.
