Question

What Java method takes an int and returns +1 or -1? The criteria for this is whether or not the int is positive or negative. I looked through the docum

Answer 1

Use Integer.signum(int i), but if you want a custom in-line bit of code:

int ans = i < 0 ? -1 : 1;

if you want 0 also:

int ans = i == 0 ? 0 : (i < 0 ? -1 : 1);
