What do these code fragments print?

a. int n = 1;

int m = -1;

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

else { System.out.print(m); }

b. int n = 1;

int m = -1;

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

else { System.out.print(m); }

c. double x = 0;

double y = 1;

if (Math.abs(x - y) < 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); }
