For, foreach.

So i normally do for example.

Code:java

 
Collection<HashSet<Block>> blockSets = chunkSplitter.values();
 

I would do something like

Code:java

 
for (HashSet<Block> : blockSets)
{
      // Do something with the hashset.
}
 

But i recently came aware of .foreach()

Code:java

 
blockSets.forEach(blocks -> { 
     // Do something with the hashset
});
 

What is the difference?

 

@JanTuck
There really is no difference, one is a for loop, one is a lambda expression (new in Java 8).

 

@AlvinB
Hmmm, okay.

 

@JanTuck

Well one also does streaming and uses Java 8 only features. It can also use implicit parallelization.

 

@mythbusterma
I prefer .foreach() i just wanted to know what is best to use.

 

@JanTuck If you are supporting servers on Java 7, the regular for loop, if you are mainly for Java 8 you can use the forEach it does in my opinion also look nicer and can take a lot less code.
