I have generated a fibonacci Series but now i want to mention on each number that which number is odd or even?

Question

public class fiboaddeven {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
int a=-1;
int b=1;
int c=0;
for(int i=1;i<=12;i++){


    c=a+b;
    a=b;
    b=c;
    System.out.println(c);
}
    }

}

The Following output is 0 1 1 2 3 5 8 13 21 34 55 89 I want 0odd 1odd 1odd 2even 3odd 5odd 8even 13odd 21even 34odd 55odd 89odd

Answer 1

What you want to use is % operator with returns remainder.

String evenOrOdd = c % 2 == 0 ? " even" : " odd";
System.out.println(c + evenOrOdd);

Answer 2

除以2时，只需测试其余部分即可：

System.out.println(c + (( c % 2 == 0 ) ? "even" : "odd" ));
