which line in the following program will cause a compiler error?

12. What will the following print ? public class Test public static void main (String[] args) boolean bl = true; boolean b2 = false; boolean b3 = true; if ((bl && b2) || (b2 && b3) || b2) System.out.print("ok"); if ((bl && b2) || (b2 && b3) 11 (bl || b2)) System.out.println("dokey"); (A) No output is produced (B) ok (C) dokey (D) Compile-time error (E) ok dokey

18. Fill in the blank so that this function returns true if the circle at xl, yl, with radius rl, has collided with the circle at x2, y2, with radius r2. boolean collided (int xl, int yi, int ri, int x2, int y2, int r2) | return A. dist (xl, yl, x2, y2) <= rl+r2 B. abs (x1-x2) >= rl+r2 && abs (yl-y2) <= rl+r2 C. A and B will both work D. Neither A nor B work but one would be correct if the <= was > E. Neither A nor B work but both would be correct if the <= was >
