Simple code, but confusing

[t.prasanna]

class C{  
static int f1(int i) {  
System.out.print(i + ",");  
return 0;  
}  
public static void main (String[] args) {  
int i = 0;  
i = i++ + f1(i);  
System.out.print(i);  
}}

When the above code compile and run, it give 1,0 (I am confused how?)
when it pass the value its passing as 1 then the value should remain same when it returns zero.
and it should be like i = 1 + 0;

As per my idea it should give 1,1

Can any one explain clearly how it works here ?

I got it how it work, if some one not clear can check the below link:p

[Webuser]

i = (i++) + f1(i);
Try that instead

[Webuser]

i = i++ + f1(i);
remember that java support linear algorythm from up to down
it gives 1.0 because
i is 1 here and f1(i); is zero :)
See yourself

As per my idea it should give 1,1

Have no idea where you take double as 0.1 here ?
Your program works just as it written... what problem you can see in it?

Inline comments how it process

class C{
static int f1(int i) { //argument i=1
System.out.print(i + ","); //prints 1,
return 0;
}
public static void main (String[] args) { //Program starts here
int i = 0; //i value is 0
i = i++ + f1(i);
/**i++ is evaluated , then i=1 and 1 is passed
*as parameter to f1(),there it prints----> 1,
*then returns 0 to statement i=i++ +f1(i)
*here,i=0+0
*which is equal to 0 and then prints 0
*so finally 1,0
*/
System.out.print(i);
