    Description copied from interface: RichIterable
    Same as the reject method with one parameter but uses the specified target collection for the results.
    Example using a Java 8 lambda expression:
```
 MutableList<Person> rejected =
     people.reject(person -> person.person.getLastName().equals("Smith"), Lists.mutable.empty());
 
```
    Example using an anonymous inner class:
```
 MutableList<Person> rejected =
     people.reject(new Predicate<Person>()
     {
         public boolean accept(Person person)
         {
             return person.person.getLastName().equals("Smith");

  - getFirst
```
public Integer getFirst()
```
    Description copied from interface: 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 Integer getLast()
```
    Description copied from interface: RichIterable
    
    Returns the last element of an iterable. In the case of a List it is the element at the last index. In the case of any other Collection, it is the last 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 last element could be any element from the Set.
