How to add try and catch around if statement?

I am unable to surround the following if statement with try and catch statement. I still see the ArrayIndexOutOfBoundsException error.

Scanner sc = new Scanner(System.in);
Scanner sc1 = new Scanner(System.in);
int i = sc.nextint();
int w = sc.nextint();
try {
 if(i == 2 && w == 3)
 {
  System.out.println(“Error. Please enter the missing elements.”);
 }
}
catch (ArrayIndexOutOfBoundsException e){
 System.out.println(“Error. Please try again.”);
}

You are not doing anything with array in mentioned if statement. Exception is caused somewhere else.

A ArrayIndexOutOfBoundsException exception that is thrown is a bug in your program that you have to correct. It is not a exception to catch.
You should never refer to an index outside the boundaries of an array.

And whatever, as mentioned this code doesn't thrown any ArrayIndexOutOfBoundsException.
