Question

**********Java language************

1-      (Conversions between Celsius and Fahrenheit) Write a class that contains the following two methods:

/** Convert from Celsius to Fahrenheit */

public static double celsiusToFahrenheit(double celsius)

/** Convert from Fahrenheit to Celsius */

public static double fahrenheitToCelsius(double fahrenheit)

The formula for the conversion is:

Celsius = (5.0 / 9) * (Fahrenheit – 32)

Fahrenheit = (9.0 / 5) * Celsius + 32

Program output should be like:

If you want to convert from Fahrenheit To Celsius press 0 vice versa press 1:

0

Enter the degree in Fahrenheit: 22

The degree in Celsius: -5.5

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.

If you want to convert from Fahrenheit To Celsius press 0 vice versa press 1:

1

Enter the degree in Celsius: 33

The degree in Celsius: 91.4

Answer 1

import java.util.Scanner;
class Main
{
/** Convert from Celsius to Fahrenheit */
public static double celsiusToFahrenheit(double celsius)
{
return (9.0/5)*celsius+32;
}
/** Convert from Fahrenheit to Celsius */
public static double fahrenheitToCelsius(double fahrenheit)
{
return (5.0/9)*(fahrenheit-32);
}
public static void main(String args[])
{
Scanner sc = new Scanner(System.in);
System.out.println("If you want to convert from Fahrenheit To Celsius press 0 vice versa press 1:");
int ch = sc.nextInt();
if(ch==0)
{
System.out.print("Enter the degree in Fahrenheit: ");
double temp = sc.nextDouble();
double result = fahrenheitToCelsius(temp);
System.out.print("The degree in Celsius: "+result);
}
else
{
System.out.print("Enter the degree in Celsius: ");
double temp = sc.nextDouble();
double result = celsiusToFahrenheit(temp);
System.out.print("The degree in Fahrenheit: "+result);
}
}
}
