How to rewrite this 3 statements to make it more compact

[shean1488]

Hi everybody, I'm just wondering what is the more eficient and compact way to write statements like this

if(site.next(1) == null) {
      return false;
}
if(site.next(2) == null) {
      return false;
}
if(site.next(3) == null) {
      return false;
}

1. You can combine multiple tests in one if, in this case ORing them together, as in
   if ( site.next(1) == null || site.next(2) == null ...

2. The contents of the if must be a boolean expression, so you don't need an if to turn that into a booelan result, eg
   return ! ( site.next(1) == null || site.next(2) == null
