hello experts,<br />
<br />
I want to check wether an &quot;int&quot; variable has any data or not.<br />
<br />
but if I do like this -<br />
int a;<br />
---<br />
---<br />
&nbsp;if(a == null){<br />
&nbsp; &nbsp; &nbsp; &nbsp;-----<br />
}<br />
<br />
<br />
then it is saying that operator == is not defined for int and null.<br />
<br />
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 ?<br />
<br />
so please suggest me how to check whether an int or a long variable has any data or not ?<br />
<br />
thank you .

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
