You are allowed to import the scanner and math methods. Not allowed to use the var variable

Solution Description TemperatureConverter A formula for converting temperature in Kelvin to degrees Fahrenheit is as follows: Fahrenheit Kelvin(9/5)-459.67 Your goal for this assignment is to write one file, TemperatureConverter.java, which prompts the user for a temperature in Kelvin, converts the temperature to degrees Fahrenheit, and then outputs the results by printing it to the terminal. Note that the temperature provided by the user may or may not have a decimal value (e.g. 42 and 3.14159 are both valid inputs). The converted result that you output should be rounded to two decimal places (e.g. 2->2.00, 28.1231 -> 28.12). You may assume that the user will enter a valid number when prompted for a temperature. Below is an example of the way a user would interact with your program. Be sure to follow the syntax exactly. Note that each execution ends with a newline character (after Fahrenheit), and that the temperature in Kelvin is identical to the input when it is printed back to the console. java TemperatureConverter Enter a temperature in Kelvin: 291.2359 291.2359 Kelvin is 64.55 degrees Fahrenheit $ java TemperatureConverter Enter a temperature in Kelvin: 278.706 278.706 Kelvin is 42.00 degrees Fahrenheit

Answer 1

import java.io.*;
import java.text.DecimalFormat;

public class TemperatureConverter
{
   public static void main(String[] args) throws IOException {
       System.out.print("Enter a temperature in Kelvin: ");
       BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
       double temperatureInKelvin = Double.parseDouble(br.readLine());
       double result = convertToFahrenheit(temperatureInKelvin);
       System.out.println("\n" + temperatureInKelvin + " Kelvin is " + roundToTwoDecimalPlaces(result) + " degrees Fahrenheit");
   }
  
   public static double convertToFahrenheit(double temperatureInKelvin)
   {
   double convertedTemperature = (((temperatureInKelvin - 273) * 9/5) + 32);
   return convertedTemperature;
   }
  
   public static double roundToTwoDecimalPlaces(double value)
   {
   DecimalFormat df = new DecimalFormat("#.##");
value = Double.valueOf(df.format(value));
return value;
   }
}
