getFirst

public V getFirst()

Description copied from interface: com.gs.collections.api.RichIterable

Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.

 {
     public void value(Person person)
     {

This method is a variant of InternalIterable.forEach(Procedure) that has a signature conflict with Iterable#forEach(java.util.function.Consumer).
