Question

As described here:

We connect the object and its method (or property) call with a logical
AND operator (&&), so the method is only invoked if the object is
truthy (not null). This technique is commonly known as ‘andand’.

In Ruby, we’re able to do this:

name = @person && @person.name

This way we don’t have to explicitly check if @person is null.

Is there a similar technique in java?

Answer 1

Try ternary operator However it’s not very similar to && technique, but works that way only.

person != null ? peson.name : <default name>
