how to handle date 1

[112055]

Hello,
I know it's wrong to check for !=null, but can anyone tell me the correct to handle this error.
The method getDaysToExpiration() returns an int

here I have ...
String tempDate = "";
if(aUser.getDaysToExpiration() !=null) tempDate = aUser.getDaysToExpiration().trim();



Generated servlet error:
D:\Tomcat\work\Standalone\localhost\WI\maintainUser$jsp.java:257: Incompatible type for int. Can't convert int to null.
if(aUser.getDaysToExpiration() !=null) tempDate = aUser.getDaysToExpiration().trim();


many thanks

Well since getDaysToExpiration() is not a Java API we have no documentation that explains the meaning of the return value. How can we tell you what to check for?

Possibly you want to check for ZERO?

if( aUser.getDaysToExpiration() != 0)

however if that function returns an (int) type then
aUser.getDaysToExpire().trim() is not going to work since you can't "trim" an integer.

You post is very confusing.

Sorry,
let me try again..
I have ....
if(aUser.getDaysToExpiration() !=null) tempDate = aUser.getDaysToExpiration().trim();

I know I can't do null and I can't do trim..

so I set it up like the following ...

int tempDate = 0;
tempDate = Integer.parseInt(aUser.getDaysToExpiration("tempDate&quot);


I got the following error message ..
Generated servlet error: D:\Tomcat\work\Standalone\localhost\WI\maintainUser$jsp.java:275: Incompatible type for method. Can't convert int to java.lang.String. tempDate = Integer.parseInt(aUser.getDaysToExpiration());

**********************************************
this method getDaysToExpiration returns an int
see below....

public int getDaysToExpiration()
{
return m_daysToPasswordExpire;
}


I am not looking at something right, can anyone tell me where I screwed up?

Thanks,
Ngai

>> int tempDate = 0;
>> tempDate = Integer.parseInt(aUser.getDaysToExpiration("tempDate&quot);

Well that is rather confusing. I think you want this:

int tempDate = aUser.getDaysToExpiration();
