Question

Write a program in java that generates a two-column table showing Fahrenheit temperatures from -40F to 120F and their equivalent Celsius temperatures. Each line in the table should be 5 degrees F more than the previous one. Both the Fahrenheit and Celsius temperatures should be accurate to 2 decimal place.

Answer 1

// program in java.

//package

import java.util.*;

// class definition

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

System.out.println("Fahrenheit \t celsius :");

// print the temperature in Fahrenheit and equivalent celsius

for(double f=-40;f<=120;f=f+5)

{

// convert Fahrenheit to equivalent celsius

double cel=((f-32)*5)/9;

// print the values

System.out.printf("%.2f \t %.2f \\", f, cel);

}

}catch(Exception ex){

return;}

}

}

Step-by-step explanation:

Run a loop from -40 to 120.To convert a temperature from Fahrenheit to equivalent celsius we use formula cel=(f-32)5/9.This will convert the temperature from Fahrenheit to celsius.increment 5 in Fahrenheit temperature and convert it to celsius till it reaches to 120.

Output:

Fahrenheit celsius :

-40.00 -40.00

-35.00 -37.22

-30.00 -34.44

110.00 43.33

115.00 46.11

120.00 48.89
