How to prevent the arrowhead anti-pattern

Question

I\'m a bit confused about how to best refactor my code into something more readable.

Consider this piece of code:

var foo = getfoo();
if(foo!=null)
{         


        

Answer 1

If you can change the stuff you are calling, you can change it to never ever return null, but a NULL-Object instead.

This would allow you to lose all the ifs completely.
