Java Programming

Hi

I have an object which shows itself as null but does not equal to null when compared. Her is the sequence

Object obj = x.getXXX();
System.out.println(obj);

if(obj != null){
System.out.println("Executing y.do something");
y.doSomething();
}

Here is the result of this

obj = null;
Executing y.doSomething.

My question is if obj is null it should not enter the loop. Please hel me with this . Any suggestions with regards to this is appreciated.

Thanks
Manoj
