R5.5 What do these code fragments print? a. int n = 1; int m = -1; if (nm) { System.out.print(n); } else { System.out.print(m); } b. int n = 1; int m = -1; if (nm) { System.out.print(n); } else { System.out.print(m); } c. double x = 0; double y = 1; if (Math.abs (xy) < 1) { System.out.print(x); } else { System.out.print(y); } d. double x = Math.sqrt(2); double y = 2; if (x * x == y) { System.out.print(x); } else { System.out.print(y); }
