Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional conditions requiring special processing – often changing the normal flow of program execution. (Wikipedia)
Java has built-in mechanism to handle exceptions. Using the try statement we can test a block of code for errors. The catch block contains the code that says what to do if exception occurs.
This problem will test your knowledge on try-catch block.
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, exception will occur and you have to report it. Read sample Input/Output to know what to report in case of exceptions.
Sample Input 0:

Java Programming
import java.util.Scanner;
import java.util.InputMismatchException;
public class Solution {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
try {
int x = scan.nextInt();
int y = scan.nextInt();
System.out.println(x/y);
} catch (InputMismatchException e) {
System.out.println(e.getClass().getName());
} catch (ArithmeticException e) {
System.out.println(e.getClass().getName() + ": / by zero");
}
