Do anyone know how to write this program in java programing? i some help for out line?

a temperature class that has two instance variables: a temperature value double and a character for the scale, either c for Celsius or F for Fahrenheit. The classe should have four constructor methods: one for each instance variable(assume zero degrees if no value is specified and Celsius if no scale is specified). One with two parameter for the two instance variable, and a no-argument constructor. include the following (10 two accessor methods to return the temperature- one to return the degree of Celsius, the other to return the degree Fahrenheit – use the this fomula to write the two methods and round to nearest tenth of a degree:


DegreeC= 5(degree-32)/9


degree=(9(degree)/5)+32;


2. three mutator methods: one to set the value, one to set the scale( F or C) and one to set both ;


3. three comparison methods, and equals method to test whether two temperature are equal, one method to test whether one temperature is greater than another

Reply:Temperature Conversion Program in Java





Here's a simple program to convert temperatures between degrees Celcius, Fahrenheit and Kelvin written in Java. There's no GUI used here - all output is done via the command line.





File: Converter.java








/**


* Conversion between temperatures in Celcius, Fahrenheit and Kelvin


* Uses conversion forumulas from the wikipedia:

// Method to convert from degrees Celcius to degrees Fahrenheit


public static float celciusToFahrenheit(float degCelcius)


{


float degFahrenheit;


degFahrenheit = degCelcius * 9/5 + 32;


return degFahrenheit;


}





// Method to convert from degrees Fahrenheit to degrees Celcius


public static float fahrenheitToCelcius(float degFahrenheit)


{


float degCelcius;


degCelcius = (degFahrenheit - 32) * 5/9;


return degCelcius;


}





// Method to convert from degrees Celcius to degrees Kelvin


public static float celciusToKelvin(float degCelcius)


{


float degKelvin;


degKelvin = degCelcius + 273.15f;


return degKelvin;


}





// Method to convert from degrees Kelvin to degrees Celcius


public static float kelvinToCelcius(float degKelvin)


{


float degCelcius;


degCelcius = degKelvin - 273.15f;


return degCelcius;


}





// Main method demonstrating usage of above methods


public static void main(String[] args)


{


System.out.print("100 degrees Celcius in Fahrenheit is: ");


System.out.println(celciusToFahrenheit(1...





System.out.print("-40 degrees Fahrenheit in Celcius is: ");


System.out.println(fahrenheitToCelcius(-...





System.out.print("0 degrees Celcius in Kelvin is: ");


System.out.println(celciusToKelvin(0));





// to convert from Kelvin to Fahrenheit, combine two methods:
