Can someone explain this syntax or provide a link that will explain this?

Question

I do not understand what this statment is doing.

(minute==minuteFloor+1 ? TIME_PICKER_INTERVAL : 0)

could someone explain it or provide a link

Thank you.

@PradeepSimha Strictly speaking this is the conditional operator, any operator with 3 arguments is a Ternary operator (but java currently only has 1 Ternary operator; the conditional operator) — Richard Tingle, Nov 07 '13 at 17:31

It's basically

if(minute == minuteFloor + 1) {
 val = TIME_PICKER_INTERVAL;
} else {
 val = 0;
}

Almost, but not quite, `Number n=(true?1:1.5);` will have `n` of type Double so the two are not strictly equivalent. See [here](http://stackoverflow.com/questions/19729588/wrong-type-in-java-conditional-assignment) for more details – Richard Tingle Nov 07 '13 at 17:27

myvariable  =   (minute==minuteFloor+1 ? TIME_PICKER_INTERVAL : 0)

In the above statement you used ?: operator which is called Ternary Operator.

it is used in below context:

if(condition)
{
//assign some value
}
else
{
//assign some other value
}

so your code does similar to below:

if(minute==minuteFloor+1)
{
myvariable=TIME_PICKER_INTERVAL;
}
else
{
myvariable=0;
}
