Author: Marty Stepp (on 2020/04/15)

You will identify various assertions as being either always true, never true or sometimes true/sometimes false at various points in program execution. The comments in the method below indicate the points of interest. 

        public static void mystery(Scanner console) {
            int y = 42;
            int z = 0;
            // Point A
            while (y != 0) {
                // Point B
                y = console.nextInt();
                if (y % 2 == 0) {
                    z++;
                    // Point C
                    y--;
                }
                // Point D
                y--;
            }
            // Point E
            System.out.println("z = " + z);
        }

Fill in each box of the the table below with ALWAYS, NEVER or SOMETIMES.

y == 0 y % 2 == 0 z == 0
Point A
Point B
Point C
Point D
Point E
