27. Consider the following two fragments of Java programs.
public void P1 (int x, int y, int z)
{
if ((x != 0) && ((y / x) == z))
z = z + 1;
System.out.println("x = " + x + " y = " + y + " z = " + z);
}
public void P2 (int x, int y, int z)
{
if (((y / x) == z) && (x != 0))
z = z + 1;
System.out.println("x = " + x + " y = " + y + " z = " + z);
}
Which of the following is true?
(A) For all x, y, and z, P1(x, y, z) and P2(x, y, z) have the same behavior.
(B) For all x and y, there exists z such that P1(x, y, z) and P2(x, y, z) behave differently.
(C) For all x and z, there exists y such that P1(x, y, z) and P2(x, y, z) behave differently.
(D) For all y and z, there exists x such that P1(x, y, z) and P2(x, y, z) behave differently.
(E) For all x, y, and z, P1(x, y, z) and P2(x, y, z) behave differently.
