Write a Java class to represent a temperature The class has

Write a Java class to represent a temperature. The class has a single data field: temperature The class has a single constructor that accepts an initial temperature provided as a double argument. If this argument is

Solution

TemperatureTester.java

import java.util.Scanner;

public class TemperatureTester {

   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.print(\"Please enter the initial temperature: \");
       double tempC = scan.nextDouble();
       TemperatureC temp = new TemperatureC(tempC);
       System.out.println(\"The current temperature in Celsius is: \"+temp.getC());
       System.out.println(\"The current temperature in Fahrenheit is: \"+temp.getF());
       System.out.println(\"The current temperature in Kelvin is: \"+temp.getK());
      
       System.out.print(\"Please enter a new temperature: \");
       double newTempC = scan.nextDouble();
       temp.setC(newTempC);
       System.out.println(\"The current temperature in Celsius is: \"+temp.getC());
       System.out.println(\"The current temperature in Fahrenheit is: \"+temp.getF());
       System.out.println(\"The current temperature in Kelvin is: \"+temp.getK());
      
   }

}

TemperatureC.java

public class TemperatureC {
   private double temperatureC;
   public TemperatureC(double temperatureC){
       this.temperatureC = temperatureC;
   }
   public void setC(double temperatureC){
       if(temperatureC > 273.15){
       this.temperatureC = temperatureC;
       }

else{
           this.temperatureC=0;
       }
   }
   public double getC(){
       return temperatureC;
   }
   public double getF(){
       return temperatureC*1.8 + 32;
   }
   public double getK(){
       return temperatureC+273.15;
   }
  
}

Output:

Please enter the initial temperature: 20
The current temperature in Celsius is: 20.0
The current temperature in Fahrenheit is: 68.0
The current temperature in Kelvin is: 293.15
Please enter a new temperature: 4000
The current temperature in Celsius is: 4000.0
The current temperature in Fahrenheit is: 7232.0
The current temperature in Kelvin is: 4273.15
