How to find whether a number is positive or negative without using if() statements or any conditional statement

Question

conditional statement like ternary operator are not allowed

Answer 1

System.out.println(number != Math.abs(number));

Answer 2

Actually Gavin should have had the shortest answer.

System.out.println(number < 0);

Answer 3

@Gavin
You don't need the ternary operator number<0 will give the same result. 😉

Answer 4

Math.abs() uses ternary. 😜

Could also do:

boolean isPositive = (myNum >> 31 == 0);

Answer 5

@Restoring faith
I like your bitwise check, but you could just == instead of negating the result.
myNum >> 31 == 0
a little easier to read and understand imo
either way it's a cool check 👍

Answer 6

@Chaotic
Oops, nice read.

Answer 7

public class Program
{
public static void main(String[] args) {

int number = -1;
boolean negative;

negative=number<0?true:false;

System.out.println(negative);

}
}

Answer 8

Nice one @Hatsy ☺

Answer 9

That's correct @ChaoticDawg but I wanted @Pranav to be curious as to why I used that.
