hello experts,

I want to check wether an "int" variable has any data or not.

but if I do like this -
int a;
---
---
 if(a == null){
       -----
}


then it is saying that operator == is not defined for int and null.

is the default value of int and long variables are 0 ? if so can I do like this if( a == 0) then does it mean that it has no data ?

so please suggest me how to check whether an int or a long variable has any data or not ?

thank you .
