Start building Java-based web applications now, even if you’re a complete newcomer to Java. Comprehensive and example-driven, this book is all you need to develop dynamic Java-based web applications using JSP, connect to databases with JSF, and put them into action using the popular open source Java web server, Apache Tomcat. Beginning Jakarta EE Web Development is a comprehensive introduction to building Java-based web applications using JSP, JSF, MySQL, and the Apache Tomcat web application server. Other APIs including JSON, JSTL, and XML parser are covered along the way. Key concepts are made easy to grasp with numerous working examples and a walk-through of the development of a complete ecommerce project. This book is written for professionals by practicing Java web application professionals and experts.

Quickly find solutions to dozens of common programming problems encountered while building Java applications, with recipes presented in the popular problem-solution format. Look up the programming problem that you want to resolve. Read the solution. Apply the solution directly in your own code. Problem solved! Java 17 Recipes is updated to reflect changes in specification and implementation since the Java 9 edition of this book. Java 17 is the next long-term support release (LTS) of the core Java Standard Edition (SE) version 17 which also includes some of the features from previous short term support (STS) releases of Java 16 and previous versions. This new edition covers of some of the newest features, APIs, and more such as pattern matching for switch, Restore Always-Strict-Floating-Point-Semantics, enhanced pseudo-random number generators, the vector API, sealed classes, and enhancements in the use of String. Source code for all recipes is available in a dedicated GitHub repository. This must-have reference belongs in your library. What You Will Learn Look up solutions to everyday problems involving Java SE 17 LTS and other recent releasesDevelop Java SE applications using the latest in Java SE technologyIncorporate Java major features introduced in versions 17, 16, and 15 into your code Who This Book Is For Programmers and developers with some prior Java experience.

Study elementary and complex algorithms with clear examples and implementations in C. This book introduces data types (simple and structured) and algorithms with graphical and textual explanations. In the next sections, you’ll cover simple and complex standard algorithms with their flowcharts: everything is integrated with explanations and tables to give a step-by-step evolution of the algorithms. The main algorithms are: the sum of three or n numbers in a loop, decimal-to-binary conversion, maximum and minimum search, linear/sequential search, binary search, bubble sort, selection sort, merging of two sorted arrays, reading characters from a file, stack management, and factorial and Fibonacci sequences. The last section of Introducing Algorithms in C is devoted to the introduction of the C language and the implementation of the code, which is connected to the studied algorithms. The book is full of screenshots and illustrations showingthe meaning of the code. What You Will Learn Implement algorithms in C Work with variables, constants, and primitive and structured typesUse arrays, stacks, queues, graphs, trees, hash tables, records, and filesExplore the design of algorithms Solve searching problems, including binary search, sorting, and bubble/selection sortProgram recursive algorithms with factorial functions and Fibonacci sequences Who This Book Is For Primarily beginners: it can serve as a starting point for anyone who is beginning the study of computer science and information systems for the first time.

Il presente testo estrapolato dal libro universitario dell'autore. Il libro nasce da una quindicennale esperienza lavorativa sui sistemi informativi e da esperienze di docenza in corsi universitari e professionali e pertanto si rivolge principalmente al pubblico degli studenti, ma anche a quello dei professionisti quale punto di partenza per chi si addentra nell'ambito dell'informatica e dei sistemi informativi per la prima volta. Con questa ed altre versioni ridotte, pubblicate per gli utenti di Kindle, l'autore si propone di approfondire ambiti specifici, che risultino di supporto alla preparazione di esami universitari o di certificazioni, ovvero di introduzione a particolari aspetti dell'informatica e dei sistemi informativi. La seguente dissertazione introduce le architetture partendo da quella di un computer, analizzandone gli aspetti hardware e software, giungendo alle reti, ad internet e alle evoluzioni del web 2.0; si passa successivamente all'introduzione dei servizi e dei sistemi distribuiti analizzando Cluster, Grid e Cloud. Si accennano i concetti di business continuity e disaster recovery per poi chiudere con il Codice dell'Amministrazione Digitale e il Sistema di Pubblica Connettivit , elementi cardine per interfacciarsi con le Pubbliche Amministrazioni.
