The Java Collections Framework provides interfaces and implementations for commonly used data structures like lists, sets, maps and queues. The core interfaces like Collection, List, Set, Queue and Map define the common operations for each type of data structure. General purpose implementations provided for these interfaces include ArrayList, LinkedList, HashSet, TreeSet, HashMap and TreeMap. Additional implementations provide functionality like synchronization or immutable collections.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. APIs and Versions
• Number one hint for programming with Java
Collections: use the API
▫ http://java.sun.com/j2se/1.5.0/docs/api/java/util
/Collection.html
• Be sure to use the 1.5.0 APIs to get the version
with generics
3. Java Collections Framework
• The Java language API provides many of the
data structures from this class for you.
• It defines a “collection” as “an object that
represents a group of objects”.
• It defines a collections framework as “a unified
architecture for representing and manipulating
collections, allowing them to be manipulated
independent of the details of their
representation.”
4. Collections Framework (cont)
• Collection Interfaces - Represent different types of collections, such as sets, lists
and maps. These interfaces form the basis of the framework.
• General-purpose Implementations - Primary implementations of the collection
interfaces.
• Legacy Implementations - The collection classes from earlier releases, Vector and
Hashtable, have been retrofitted to implement the collection interfaces.
• Wrapper Implementations - Add functionality, such as synchronization, to other
implementations.
• Convenience Implementations - High-performance "mini-implementations" of
the collection interfaces.
• Abstract Implementations - Partial implementations of the collection interfaces
to facilitate custom implementations.
• Algorithms - Static methods that perform useful functions on collections, such as
sorting a list.
• Infrastructure - Interfaces that provide essential support for the collection
interfaces.
• Array Utilities - Utility functions for arrays of primitives and reference objects.
Not, strictly speaking, a part of the Collections Framework, this functionality is being
added to the Java platform at the same time and relies on some of the same
infrastructure.
5. Collection interfaces
• The core collection interfaces encapsulate
different types of collections. They represent the
abstract data types that are part of the
collections framework. They are interfaces so
they do not provide an implementation!
6. public interface Collection<E>
extends Iterable<E>
• Collection — the root of the collection hierarchy. A
collection represents a group of objects known as its
elements. The Collection interface is the least common
denominator that all collections implement and is used
to pass collections around and to manipulate them when
maximum generality is desired. Some types of
collections allow duplicate elements, and others do not.
Some are ordered and others are unordered. The Java
platform doesn't provide any direct implementations of
this interface but provides implementations of more
specific subinterfaces, such as Set and List.
7. A note on iterators
• An Iterator is an object that enables you to traverse
through a collection and to remove elements from the
collection selectively, if desired. You get an Iterator
for a collection by calling its iterator() method. The
following is the Iterator interface.
public interface Iterator<E> {
boolean hasNext();
E next();
void remove(); //optional
}
8. public interface Set<E>
• Set — a Collection<E>
extendscollection that cannot contain duplicate
elements. This interface models the
mathematical set abstraction and is used to
represent sets, such as the cards comprising a
poker hand, the courses making up a student's
schedule, or the processes running on a
machine.
9. public interface List<E>
extends Collection<E> (sometimes called a
• List — an ordered collection
sequence). Lists can contain duplicate elements.
The user of a List generally has precise control
over where in the list each element is inserted
and can access elements by their integer index
(position). If you've used Vector, you're familiar
with the general flavor of List.
10. public interface Queue<E>
extends Collection<E>
• Queue — a collection used to hold multiple
elements prior to processing. Besides basic
Collection operations, a Queue provides
additional insertion, extraction, and inspection
operations.
11. Note on Comparator interface
• Comparator is another interface (in addition to
Comparable) provided by the Java API which
can be used to order objects.
• You can use this interface to define an order that
is different from the Comparable (natural)
order.
12. public interface SortedMap<K,V>
extends Map<K,V>
• SortedMap — a Map that maintains its
mappings in ascending key order. This is the
Map analog of SortedSet. Sorted maps are used
for naturally ordered collections of key/value
pairs, such as dictionaries and telephone
directories.
13. General-purpose Implementations
Interfaces
Implementations
Hash table
Set
Resizable array
Linked list
TreeSet
(sorted)
HashSet
List
Tree
(sorted)
Hash table + Linked list
LinkedHashSet
LinkedList
ArrayList
Queue
Map
HashMap
TreeMap
(sorted)
LinkedHashMap
Note the naming convention
LinkedList also implements queue and there is a PriorityQueue implementation (implemented with heap)
14. Other implementations in the API
• Wrapper implementations delegate all their real
work to a specified collection but add (or
remove) extra functionality on top of what the
collection offers.
▫ Synchronization Wrappers
▫ Unmodifiable Wrappers
• Convenience implementations are miniimplementations that can be more convenient
and more efficient than general-purpose
implementations when you don't need their full
power
▫
▫
▫
▫
List View of an Array
Immutable Multiple-Copy List
Immutable Singleton Set
Empty Set, List, and Map Constants
15. public interface Map<K,V>
• Map — an object that maps keys to values. A
Map cannot contain duplicate keys; each key can
map to at most one value. If you've used
Hashtable, you're already familiar with the
basics of Map.
16. public interface SortedSet<E>
extends Set<E> that maintains its elements in
• SortedSet — a Set
ascending order. Several additional operations
are provided to take advantage of the ordering.
Sorted sets are used for naturally ordered sets,
such as word lists and membership rolls.
17. Making your own implementations
• Most of the time you can use the
implementations provided for you in the Java
API.
• In case the existing implementations do not
satisfy your needs, you can write your own by
extending the abstract classes provided in the
collections framework.
