null check for object

[Shilpa B, modificado hace 11 años.]

As I'm fetching data from web services and displaying in my portlet. Around 5 filed are there, in that sometimes some of fields may be null. because of this filed whole portlet not getting displayed.

As i have to check for null, and I'm doing in this way. Is this the correct approach for null check?

String reqLastRD = fetching form web service;
if (reqLastRD != null)
{
reqLastRD = fetching form web service;
} else
{
reqLastRD = "";
}
renderRequest.setAttribute("reqLastRD", reqLastRD);

please suggest me the right approach for null check.

thank you in advance...

Try using Validator.isNotNull function from the Validator Class.
