I cry a little when I code in java

These two pieces of code do the same thing.

Java

Collection<String> output = Collections2.transform(cur.toArray(), new Function<DBObject, String>(){
  public String apply(final DBObject input){
    return input.toString();
  }
});
String o = Joiner.on(",").join(output);

Ruby

o = cur.map { |e| e.to_s }.join(",")
