HackerRank Java Exception Handling (Try-catch) solution

In this HackerRank Java Exception Handling (Try-catch) problem in java programming, you will be given two integers x and y as input, you have to compute x/y. If x and y are not 32 bit signed integers or if y is zero, an exception will occur and you have to report it. Read sample Input/Output to know what to report in case of exceptions.

import java.util.regex.*;

public class Solution {

    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
        Scanner scan = new Scanner(System.in);
    try {
      int x = scan.nextInt();
      int y = scan.nextInt();
      System.out.println(x / y);
    } catch(ArithmeticException | InputMismatchException e) {
      if (e instanceof ArithmeticException) {
        System.out.println("java.lang.ArithmeticException: / by zero");
      } else if (e instanceof InputMismatchException){
        System.out.println("java.util.InputMismatchException");
      }
    }
    scan.close();
        
    }
}

            System.out.println(a/b);            
        } catch (java.util.InputMismatchException ime) {
            System.out.println("java.util.InputMismatchException");
        } catch (java.lang.ArithmeticException ae) {
            System.out.println("java.lang.ArithmeticException: / by zero");
        }        
    }
}

The third solution in java8 programming

import java.io.*;
import java.util.*;

public class Solution {

   
         public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named
        Solution. */
        Scanner sc=new Scanner(System.in);
        try{
            int a=sc.nextInt();
            int b=sc.nextInt();
            System.out.println(a/b);
        }
        catch(Exception e){
            if(e instanceof java.lang.ArithmeticException)
                System.out.println(e.toString());
            if(e instanceof java.util.InputMismatchException)
                System.out.println("java.util.InputMismatchException");
        }
    }
    
}
