Java 8 Optional instead of if

Question

I have problem with Optional and I don't know how to handle it.

public void check(String name) {
   if (name != null)
      doSomething(name);
   else 
      doMore();
} 

How to change this if into Optional?

Answer 1

There is a very neat method for that, but present in jdk-9...

public void check(String name){
     Optional.ofNullable(name)
            .ifPresentOrElse(YourClass::doSomething, YourClass::doMore);
} 

assuming doSomething and doMore are static methods... If not an instance should be used, like this::doSomething or this::doMore
