public class FahrenToCelsius

{

    public static void main(String args[])throws IOException

    {

        int ch,c,f;

        InputStreamReader ab=new InputStreamReader(System.in);

        BufferedReader br=new BufferedReader(ab);

        // Menu List

        System.out.println("Enter 1. Farenheit to Celsius:");

        System.out.println("Enter 2. Celsius To Farenheit:");

        System.out.print("Enter Choice :");

        ch=Integer.parseInt(br.readLine());

        // switch statement

        switch(ch)

        {

            case 1:

                System.out.print("Enter Temperature in Farenheit :");

                f=Integer.parseInt(br.readLine());

                c=((f-32)*5)/9;

                System.out.println("Temperature in Celsius :"+c);

                break;

            case 2:

                System.out.print("Enter Temperature in Celsius :");

                c=Integer.parseInt(br.readLine());

                f=(9*c/5)+32;

                System.out.println("Temperature in Farenheit :"+f);

                break;

       }

    }

}

Output :

Enter 1. Farenheit to Celsius:

Enter 2. Celsius To Farenheit:

Enter Choice :1

Enter Temperature in Farenheit :100

Temperature in Celsius :37

Enter 1. Farenheit to Celsius:

Enter 2. Celsius To Farenheit:

Enter Choice :2

Enter Temperature in Celsius :100

Temperature in Farenheit :212
