When to use ‘Java util. Objects.*’？

I'm browsing the seven functions of Java. They talked about Java util. Objects course

What I can't understand is the functional difference between them

java.util.Objects.toString(foo)
vs
foo == null ? "":foo.toString()

What I can only see is an empty check and functional notation instead of OOP style

What did I miss?

Solution

java. util. Objects. The main advantage of toString () is that you can easily use it for potentially null return values instead of creating new local variables (or worse, calling the function twice)

comparison

Foo f = getFoo();
String foo = (f==null) ? "null" : f.toString();

Or a daunting and seductive mistake

String foo = (getFoo()==null) ? "null" : getFoo().toString()

To objects based Version of toString

String foo = Objects.toString(getFoo());
