Entering in the loop,even if the value is null or empty

[swati.jyoti]

if ((req_.getEmpData()!=null )||(req_.getEmpData()!=""))
{
itemsEmp=req_.getEmpData().split(",");
}

I dont know ,Y the control is entering in the block when i am hardcoding the
empdata to null
as req.setEmpData(null);
And also at the debug time it showing the value as-->
"req_.getEmpData()"= null

Dont know what is the problem,Y the control is entering in the loop??

Pls do help me with the Problem

Thanks in advance. :)

Don't use == (or !=) for Strings. Change the second half of that to use the equals method.

Its giving the error when i am debugging --->java.lang.NullPointerException at equals(Object)

if (!(req_.getEmpData().equals(null) )||!(req_.getEmpData().equals("")))
{
}

[masijade]

I said to do that for the second half of the statement, not the first half. The null check must be done with == or != as you cannot dereference null as that error shows.

[masijade]

Also, you want to use "and" (&&) not "or" (||) as all strings will be either "not null" or "not empty". An "empty" string is "not null" and a null string is "not empty".

None is working..I have tried each and every possibe cases suggested by u..

Ye Gods

if ((req_.getEmpData() != null) && (!req_.getEmpData().equals("")))

[swati.jyoti]

Exception in thread "main" java.lang.NullPointerException..
Its pointing to that line only
since its entering in the loop
and then trying to split the null string.

:sigh: Show the entire code in that area. and mark the npe line. PS an if statement is a statement that controls a block, it is not a loop. It is couter-productive to think of it as one.

Also, if that line, as I typed it, is throwing an NPE, then it is req_ that is null, not the result of req_.getEmpData().
