How do I check a Long value for null in Java?
Will this work?
if ( longValue == null) { return blah; }
Primitive data types cannot be null
. Only Object
data types can be null
.
int
, long
, etc... can't be null
.
If you use Long
(wrapper class for long
) then you can check for null
's:
Long longValue = null;
if(longValue == null)
