Confusion again???

[Joe San]

Hi Ranchers,

Consider the code below,

1. public class Alpha1 {
2. public static void main( String[] args ) {
3. boolean flag; int i=0;
5. do {
6. flag = false;
7. System.out.println( i++ );
8. flag = i < 10;
9. continue;
10. } while ( (flag)? true:false );
11. }
12. }

What is the result?

When run, it prints 0 through 9, but I feel that it enters an infinite loop?? bceause the ternary operator always assignes true to the flag in the statement while ( (flag)? true:false )...........Anyone on this???

Thanks in advance.

Hi ranchers,

no,
while((flag)?true:false)
this assigns nothing to the flag. It just returns true, when flag is true and false when flag is false.
It's just the same as if you simple coded
while(flag);

By the way, the continue does nothing here, it just jumps to the while clause.


Yours,
Bu.

Thanks Bu,

I understand it now. If any of fellow ranchers come across questions like this elsewhere, please post them here. That would be helpful for people like me.

Thanks all.
