“To have another language is to possess a second soul.”

-------------------
FP strongly discourages changing the state of a variable once initialized. This has a profound effect upon concurrency. If you can’t change the state of a variable, you can’t have a race condition. If you can’t update the value of a variable, you can’t have a concurrent update problem.

8. Forced Null-Checks

In Java, the method signature of a public method does not tell you if
a returned value can be null or not. Take this signature for instance:

public List<Item> getSelectedItems()

What happens when no item is selected? Does this method then return
null? Or does it return an empty list? We do not know for sure without
looking into the implementation of this method (except we are very
lucky in this case that the signature has a good javadoc description
of the return type). There are two mistakes a developer could possibly
make: (1)fForgetting to check the return value for null when it can be
null, resulting in the famous NullPointerException, or; (2) checking
it for null although it never can be null, resulting in needless code.
