When the method Run encounters an instance where number2 == 0 i want it to throw an exception BUT i dont want the program to stop. How does that work?

Is the β€œbase” keyword only used to get the superclasses info?

βœ… Exception handling
I'm trying to understand exceptions but i'm having a hard time. So when an error occurs in my program. For example :
int number = Console.Readline();
Console.Writeline($"{number}");
int number = Console.Readline();
Console.Writeline($"{number}");
If the input here in this case wasn't an integer but a string. The program would crash right? And to prevent it from crashing we use exception handling with try and catch ?
