```
public MutableCollection<T> select(Predicate<? super T> predicate)
```
 Description copied from interface: RichIterable
 Returns all elements of the source collection that return true when evaluating the predicate. This method is also commonly called filter.

```
 RichIterable<Person> selected =

 public boolean accept(Person person)
 {
 return person.getAddress().getCity().equals("London");
 }
 });

 - reject
```
public MutableCollection<T> reject(Predicate<? super T> predicate)
```
 Description copied from interface: RichIterable
 Returns all elements of the source collection that return false when evaluating of the predicate. This method is also sometimes called filterNot and is the equivalent of calling iterable.select(Predicates.not(predicate)).
 Example using a Java 8 lambda expression:
```
 RichIterable<Person> rejected =
 people.reject(person -> person.person.getLastName().equals("Smith"));
 
```
 Example using an anonymous inner class:
```
 RichIterable<Person> rejected =

 {
 return person.person.getLastName().equals("Smith");
 }

 - flatCollect
```
public <V> MutableCollection<V> flatCollect(Function<? super T,? extends Iterable<V>> function)
```
 Description copied from interface: RichIterable
 flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.
 Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:
```
 Function<Person, List<Address>> addressFunction = Person::getAddresses;
 RichIterable<Person> people = ...;
 
```
 Using collect returns a collection of collections of addresses.
```
 RichIterable<List<Address>> addresses = people.collect(addressFunction);
 
```
 Using flatCollect returns a single flattened list of addresses.
```
 RichIterable<Address> addresses = people.flatCollect(addressFunction);
 
```

 - groupBy
```
public <V> MutableMultimap<V,T> groupBy(Function<? super T,? extends V> function)
```
 Description copied from interface: RichIterable
 For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.
 Example using a Java 8 method reference:
```
 Multimap<String, Person> peopleByLastName =
 people.groupBy(Person::getLastName);
 
```
 Example using an anonymous inner class:
```
 Multimap<String, Person> peopleByLastName =
 people.groupBy(new Function<Person, String>()
 {
 public String valueOf(Person person)
 {
 return person.getLastName();
 }
 });
