Optional of nullable on something giving NullPointerException

Question

I m trying to use Optional.ofNullable on an a getter that is throwing a NullPointerException :

My code is as follow :

Individual individual = null;

Optional.ofNullable(individual.getIndividualName());

Throwing a NullPointerException here is normal since individual is null

I want to find a pretty way to avoid this exception and get null as result of

Optional.ofNullable(individual.getIndividualName());

The solution in Null check chain vs catching NullPointerException is very heavy. I try it in a jUnit test and takes several seconds to get the result!

Answer 1

The variable individual is null and hence the exception.

You should rather have

Optional.ofNullable(individual)
        map(Individual::getIndividualName);

The above returns Optional<Type> where Type is the return type of getIndividualName()

It shouldn't be the case You might be doing something wrong
