Chapter 3, Problem 4RE

What do these code fragments print?

1. a. int n = 1;

  int m = -1;

  if (n < -m) { System.out.print(n); }

  else { System.out.print(m); }

1. b. int n = 1;

  int m = -1;

  if (-n >= m) { System.out.print(n); }

  else { System.out.print(m); }

1. c. double x = 0;

  double y = 1;

  if (Math.abs(x - y) < 1) { System.out.print(x); }

  else { System.out.print(y); }

1. d. double x = Math.sqrt(2);

  double y = 2; if (x * x == y) { System.out.print(x); }

  else { System.out.print(y); }
