Assertions

	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 x = 0;
	int y = 1;
	int next = console.nextInt();
	<span class="assertionpoint">// Point A
	while (next != 0) {
		<span class="assertionpoint">// Point B
		y = y * next;
		if (next < 0) {
			x++;
			<span class="assertionpoint">// Point C
		}
		next = console.nextInt();
		<span class="assertionpoint">// Point D
	}
	<span class="assertionpoint">// Point E
	System.out.println(y + " " + x);
}

1) next < 0 

2) next == 0 

3) x > 0
