Answer 1

Yes actually when 25 is divided by 5 the it will live no remainder means it will return null value but you had defined again null value as number and you know that compilers always return 0 or 1 so it will consider null as 0 and because of your 4th line code null (0) become 0 which is an int.

if you want that second condition should print then directly use z there instead of zero because zero contain 0 and z contains null value

Answer 2

If zero have any value then it will return true . But if zero will contain null value then it will go for else

Answer 3

hay Jyoti Rani Who said 0 is a null value . Infact 0 is a value itself . If you want to give it null just use "" double quote without any string or space in it because spaces may also considered as values
