+Ensure a class only has limited number of instances and provide a global point of access to them.
+
+## Explanation
+
+Real world example
+
+> The Nazgûl, also called ringwraiths or the Nine Riders, are Sauron's most terrible servants. By definition there's always nine of them.           
+
+In plain words
+
+> Multiton pattern ensures there's predefined amount of instances available globally.   
+
+Wikipedia says
+
+> In software engineering, the multiton pattern is a design pattern which generalizes the singleton pattern. Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map.
+
+**Programmatic Example**
+
+Nazgul is the multiton class.
+
+```java
+public enum NazgulName {
+
+  KHAMUL, MURAZOR, DWAR, JI_INDUR, AKHORAHIL, HOARMURATH, ADUNAPHEL, REN, UVATHA;
+}
+
+public final class Nazgul {
+
+  private static Map<NazgulName, Nazgul> nazguls;
+
+  private NazgulName name;
+
+  static {
+    nazguls = new ConcurrentHashMap<>();
+    nazguls.put(NazgulName.KHAMUL, new Nazgul(NazgulName.KHAMUL));
+    nazguls.put(NazgulName.MURAZOR, new Nazgul(NazgulName.MURAZOR));
+    nazguls.put(NazgulName.DWAR, new Nazgul(NazgulName.DWAR));
+    nazguls.put(NazgulName.JI_INDUR, new Nazgul(NazgulName.JI_INDUR));
+    nazguls.put(NazgulName.AKHORAHIL, new Nazgul(NazgulName.AKHORAHIL));
+    nazguls.put(NazgulName.HOARMURATH, new Nazgul(NazgulName.HOARMURATH));
+    nazguls.put(NazgulName.ADUNAPHEL, new Nazgul(NazgulName.ADUNAPHEL));
+    nazguls.put(NazgulName.REN, new Nazgul(NazgulName.REN));
+    nazguls.put(NazgulName.UVATHA, new Nazgul(NazgulName.UVATHA));
+  }
+
+  private Nazgul(NazgulName name) {
+    this.name = name;
+  }
+
+  public static Nazgul getInstance(NazgulName name) {
+    return nazguls.get(name);
+  }
+
+  public NazgulName getName() {
+    return name;
+  }
+}
+```
+
+And here's how we access the Nazgul instances.
+
+```java
+    LOGGER.info("KHAMUL={}", Nazgul.getInstance(NazgulName.KHAMUL));
+    LOGGER.info("MURAZOR={}", Nazgul.getInstance(NazgulName.MURAZOR));
+    LOGGER.info("DWAR={}", Nazgul.getInstance(NazgulName.DWAR));
+    LOGGER.info("JI_INDUR={}", Nazgul.getInstance(NazgulName.JI_INDUR));
+    LOGGER.info("AKHORAHIL={}", Nazgul.getInstance(NazgulName.AKHORAHIL));
+    LOGGER.info("HOARMURATH={}", Nazgul.getInstance(NazgulName.HOARMURATH));
+    LOGGER.info("ADUNAPHEL={}", Nazgul.getInstance(NazgulName.ADUNAPHEL));
+    LOGGER.info("REN={}", Nazgul.getInstance(NazgulName.REN));
+    LOGGER.info("UVATHA={}", Nazgul.getInstance(NazgulName.UVATHA));
+    
+    // KHAMUL=com.iluwatar.multiton.Nazgul@2b214b94
+    // MURAZOR=com.iluwatar.multiton.Nazgul@17814b1c
+    // DWAR=com.iluwatar.multiton.Nazgul@7ac9af2a
