Question

（java））Write a “Temperature Conversion” program.

Declare choice, tempIn, tempOut variables

Prompt the user with the messages to choose: 1) Centigrade to Fahrenheit, 2) Fahrenheit to centigrade.

Prompt the user for temperature value (tempIn) to convert.

Calculate new tempOut. The calculation of the new tempOUT depends on choice 1 or 2 above.\

( Lookup up the C to F formula online, loop up the F to C formula online )

Print out the the F and the C temps.

Be sure to use the C and F temperature notation ASCII symbol.

Answer 1

If you have any doubts, please give me comment...

import java.util.Scanner;

public class TemperatureConversion {

    public static void main(String[] args) {

        int choice;

        double tempIn, tempOut;

        Scanner scnr = new Scanner(System.in);

        System.out.println("MENU");

        System.out.println("1) Centigrade to Fahrenheit");

        System.out.println("2) Fahrenheit to centigrade.");

        System.out.print("Enter your choice: ");

        choice = scnr.nextInt();

        if (chocie == 1 || choice == 2) {

            System.out.print("Enter temperature value: ");

            tempIn = scnr.nextDouble();

            if (choice == 1) {

                tempOut = (tempIn * 9 / 5.0) + 32;

                System.out.println("C = " + tempIn + "\u00B0, F = " + tempOut + "\u00B0");

            } else {

                tempOut = (tempIn - 32) * 5 / 9.0;

                System.out.println("C = " + tempIn + "\u00B0, F = " + tempOut + "\u00B0");

            }

        } else {

            System.out.println("Invalid choice\n");

        }

    }
