What will this small program output? class Main { private static int foo(int a) { int b = 3; return b; } * a private static int bar(int b) { int a = 19 b; return a; - } private static int baz(int a) { int b = a + 4; return b; } public static void main(String[] args) { int a = 7; int b = 5; int x = foo(bar(a)) + baz(b); System.out.println(x); } }
