Given: class Scoop { static int thrower() throws Exception { return 42; } public static void main(String [] args) { try { int x = thrower(); } catch (Exception e) { X++; } finally { System.out.printIn("x = " + ++x); } } } What is the result?

technology programming languages

x = 42
x = 43
x = 44
Compilation fails.
The code runs with no output
