Java Optional with multiple commands and return object

Question

Attempting to execute multiple commands and return an Object (ResponseEntity) using Optional.ifPresentOrElse

More complex does not work:

return ifPresentOrElse(
           repoService.findById(inId),
           i -> {
               i.setStatus(inStatus);
               repoService.save(i);
               ResponseEntity.ok().body(i);
           }, 
           () -> {
               LOG.error("Object not available");
               ResponseEntity.notFound().build();
           });

Simpler works but doesn't execute all the commands required:

Optional<I> iOptional = repoService.findById(inId);
        
return iOptional.map(i -> ResponseEntity.ok().body(i))
                .orElse(ResponseEntity.notFound().build());

Is there away to achieve this using Optional functions?

Answer 1

Use Optional.map and Optional.orElseGet, like this:

var responseEntity = repoService.findById(inId)
  .map(record -> {
    record .setStatus(inStatus);
    repoService.save(record);
    return ResponseEntity.ok().body(record);
  }).orElseGet(() -> {
    LOG.error("Object not available");
    return ResponseEntity.notFound().build();
  });
