primitives dont have null value. default have for an int is 0.

if(person.getId()==0){}

Default values for primitives in java:

Data Type Default Value (for fields)

byte                0
short               0
int                 0
long                0L
float               0.0f
double              0.0d
char               '\u0000'
boolean             false

Objects have null as default value.
