        }
        catch (ExceptionType1 ex1)
        {
            // Handle ExceptionType1
        }
        catch (ExceptionType2 ex2)
        {
            // Handle ExceptionType2
        }
        finally
        {
            // Code that always executes, 
            //whether an exception is thrown or not
        }
    }
}

PYTHON

class ExceptionHandlingExample:
    def main(self):
        try:
            # Code that may throw an exception
        except ExceptionType1 as ex1:
            # Handle ExceptionType1
        except ExceptionType2 as ex2:
            # Handle ExceptionType2
        finally:
            # Code that always executes, 
            #whether an exception is thrown or not

C#:

try-catch Blocks:
Similar to Java, C# relies on try-catch blocks to manage exceptions gracefully.
Multiple Catch Blocks:
C# allows the use of multiple catch blocks, each tailored to handle a specific type of exception. This feature promotes code cleanliness and brevity.
