WR 416 Lecture 9: Channel Flow

9. Enter the best choice from the list of choices A-W above for what this program displays _ // caution - this may be a trick question int XPOS, Y POS; void setup() { y Pos = 0; xPos = width/2; void draw() { background (255); int ball Size = 10; fill(0); ellipse (xPos, ypos, ballSize, ballSize); yPos = y Pos + 1; xPos = xPos + y Pos/(height/2);

36. True or false, the output of these two code fragments is always the same? That is, for a given pair of values for x and y, these fragments will both print A or both print nothing. if (x < 20 && y < 30) { println("A"); if (x < 20){ if (y < 30) { println("A");

Syscene.UU.VIILIIllesUIL! 8. Consider a method with the header: public static boolean method (int x, boolean y) Is boolean b = method(10+2, true &&0) a valid way to call it? Write YES or NO
