  - reject
```
public <R extends Collection<Integer>> R reject(Predicate<? super Integer> predicate,

```
    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");
         }
     }, Lists.mutable.empty());
 
```
    Specified by:
    
    reject in interface RichIterable<Integer>
    
    Overrides:
    
    reject in class AbstractRichIterable<Integer>
    
    Parameters:
    
    predicate - a Predicate to use as the reject criteria
    
    target - the Collection to append to for all elements in this RichIterable that cause Predicate#accept(Object) method to evaluate to false
    
    Returns:
    
    target, which contains appended elements as a result of the reject criteria

  - toIntArray
```
public int[] toIntArray()
```
    Converts the interval to an Integer array
  - toString
```
public String toString()
```
    Description copied from class: AbstractRichIterable
    
    Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).
    
    This implementation creates an empty string buffer, appends a left square bracket, and iterates over the collection appending the string representation of each element in turn. After appending each element except the last, the string ", " is appended. Finally a right bracket is appended. A string is obtained from the string buffer, and returned.
    
    Specified by:
    
    toString in interface RichIterable<Integer>
    
    Overrides:
    
    toString in class AbstractRichIterable<Integer>

  - 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.

  - getLast
```
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.
