            int b = 0;
            int result = a / b;   // may cause an exception
            System.out.println("Result: " + result);
        } catch (ArithmeticException e) {
            System.out.println("Error: Cannot divide by zero!");
        } finally {
            System.out.println("Execution completed.");
