The following Code is to accept the temperature by the user in fahrenheit and convert it to celsius. Another Exception that can be thrown is 'InputMismatchException'.
Code:-

import java.util.*;
public class TemperatureConversion{
    Scanner scan=new Scanner(System.in);
    float fah, cel;
    public void input(){
        try{
            System.out.println("Enter Temperature in Fahrenheit: ");
            fah=scan.nextInt();
        }
        catch(NumberFormatException e){
            System.out.println("Error Code: "+e);
            System.exit(0);
        }
    }

    public void compute(){
        cel=(float) ((fah-32)/1.8);
        System.out.println("Fahrenheit\t\tCelsius");
        System.out.println(fah+"\t\t\t"+cel);
    }

    public static void main(String[] args){
        TemperatureConversion temp=new TemperatureConversion();
        temp.input();
        temp.compute();
    }
}

Output:-
Enter Temperature in Fahrenheit:
