Which of the following statements is true?

``` public class TestA { public static void main(String[] args) { int x = 2; int y = 20 int counter = 0; for (int j = y % x; j < 100; j += (y / x)) { counter++; } } } public class TestB { public static void main(String[] args) { int counter = 0; for (int j = 10; j > 0; --j) { ++counter; } } } ``` a. The value of counter will be different at the end of each for loop for each class. b. The value of j will be the same for each loop for all iterations c. Both (a) and (b) are true. d. Neither (a) nor (b) is true.

Write a static method findFigure(picture, threshold), where picture is a two-dimensional array of double values. The method should return a new twodimensional array whose elements are either 0.0 or 1.0. Each 1.0 in this new array indicates that the corresponding value in picture exceeds threshold times the average of all values in picture. Other elements in the new array are 0.0.

For example, if the values in picture are the average value is 5.55. The resulting array for a threshold of 1.4 would be and the resulting array for a threshold of 0.6 would be
