Question

Int a=4;
Int b=8;
If((b-a--) >=0)
If((b+a)%2==1)
System.out.println(a*b);
else
System.out.println (b+a);

Can anyone explain how the answer to this is 24?
Thanks.

Answer 1

4>0 then 8+3 % 2 == 1
so output is 3*8 = 24

Answer 2

Thanks man

Answer 3

The value of a is changed to 3 in the third line isn't it? Don't we need to do something like a=a-- for that to happen?

Answer 4

a-- means a=a-1
