Why Strange Answers Java?

Question

I have following code

int num1 = 8;
int num2 = 5;

double ans = num1/num2;

System.out.println(ans); // result is 1.0

why i am getting 1.0 in ans where it should be 1.6 ?

Have you done any prior research? For example tried to read **anything** about the nature of the primitive data types that you are using? — GhostCat, Jun 08 '15 at 11:06
I recommend reading this very closely: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html — Daniel M., Jun 08 '15 at 11:08
Obvious homework question, yes this board is for people of all levels but please do some basic research before posting. — Reginald, Jun 08 '15 at 11:14

No, it not should be 1.6

Here how it is complied

int / int -> result int.

i.e. 8/5 = 1

then int value assigned to double.

int -> double // is 1.0

if you use this :

double ans =(double) num1/num2;

this will give 1.6 because num1 will be considered as double and

double / int -> result double.
