    Scanner in = new Scanner(System.in);

        try{
        int x = in.nextInt();
        int y = in.nextInt();
        if(x>=0 && y>=0)
        System.out.println(x/y);
    }catch(InputMismatchException ee){
        System.out.println("java.util.InputMismatchException");
    }
        catch(Exception e){
        System.out.println(e.toString());
    }


}

    Initially in catch block i simply wrote sysout(e); to print exception message.

    But one of the test case failed for arithmetic exception so i used ternery operator like below instaed of writing catch block for all exceptions.

    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 x = 0;
        int y = 0;


        x = sc.nextInt();
        y = sc.nextInt();

       System.out.print(x/y);

    }catch(Exception e){
        String emsg = (e.getClass().getName().equalsIgnoreCase("java.lang.ArithmeticException")) ? "java.lang.ArithmeticException: / by zero" : e.getClass().getName();
        System.out.print(emsg);
    }
    finally{
        sc.close();
    }



}

    }
