Serializable and Clonable Interface

• Usually, we can use collections to hold and transfer objects from one location to another location
• To provide support for this requirement, every collection class by default implements serializable and clonable interface

Random Access Interface

• Implemented by ArrayList and Vector
• ArrayList and Vector class implements RandomAccessInterface so that any random element in the collection we can access with the same speed
• RandomAccess is a marker interface where required ability will be provided automatically by the JVM
