                        int a = 20, b = 0;

                        int div = a/b;

                  }catch(ArithmeticException e){

                        System.out.println("Division by 0 not allowed");

                  }


                  try{

                        int arr[] = {1,2,3,4,5};

                        System.out.println(arr[10]);
