Question

I am having difficultie while validating a long variable if it is null.
The Code which I am using is :

long late_in= latein_hours.getTime();

It will show an error that java null pointer exception. So how can I validate if it is null then make it equal to zero.

Thanks

Answer 1

long late_in = 0;
if(latein_hours!=null){
    late_in= latein_hours.getTime();
}

Primitive can’t be null, only reference to object can hold null value
