As a domain expert in the Batman universe, I can provide an informed answer to your question. The character of Bruce Wayne in "Batman Begins" is portrayed as a young adult. While the film does not explicitly state his age, it is generally accepted that Bruce Wayne is in his mid-to-late 20s during the events of this film. This is based on the character's backstory, which involves him leaving Gotham for about a decade to travel the world and train before returning to Gotham to become Batman. The film is a reboot of the Batman franchise, which means it provides a fresh start for the character's story, and it is not strictly tied to the continuity of previous Batman films or comics.
