Java Blooper #2: Must be a Better Way...

It's Monday, which means it's time for another blooper... What's wrong with this code?

boolean hasThing( List things, Thing thing ) {
  for ( int i=0; i < things.size(); i++ ) {
    if ( thing.equals( things.get( i ) ) ) {
      return true;
    }
  }
  return false;
}

Update: Minor edit to add missing parenthesis from if statement that got "lost in translation" en-route to the blog :)
