public class Fibonacy {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
int a=0;
int b=1;
for(int i=0;i<10;i++)
{
   
    a=a+b;
    //System.out.println("a data"+a);
    b=a-b;
    System.out.println("b data "+b);
}
    }

}

Output:
b data 0
b data 1
b data 1
b data 2
b data 3
b data 5
