Can you store a variable inside a if-clause?

Question

I\'m kinda waiting for a \'no\' answer on this question.

I was interested if you can save a variable at the same time when you checking it in an if-clause.

Answer 1

Actually I think that is a way to do this using Java Optional, here's an example:

Optional.ofNullable("text").ifPresent( $0 -> {
  System.out.println($0.toUpperCase());
});

Or in your case:

  if(foo != null){
      Optional.ofNullable(foo.getBar()).ifPresent(bar -> {
          System.out.println("Success: " + bar);
      });
  }
