I just wanted to make sure...because in my company i see previous code which checks for null when an ArrayList is returned ....

Welcome to the Ranch.

i see previous code which checks for null when an ArrayList is returned ....


Returned from where? If it is from a method then it can indeed be null.

When you create an object using the new operator then you will indeed never get null.

It makes no sense to check for null after using new:

If somewhere in the "more code" (line 8 in your example), dataList is set to null, then the getData() method will return null. But the new operator itself never returns null, so there's no need to check for that.

However - note that if the constructor throws an exception which you ignore, then the reference will indeed be null and result in a nasty surprise later.
