Fondamenti di Java

Discover the unique features of Java and understand why it's a recommended programming language to learn. Write your first Java code and explore how to print text to the console.

Learn the basics of programming, dive into primitive data types, and explore operations with them. Write code that performs mathematical tasks and evaluates conditions for seamless execution.

Explore various loops such as for, while, and do-while, which are essential in any programming language. Loops enable efficient iteration over large datasets, saving significant time. Apply them extensively in tasks like sorting, working with arrays, collections, and more.

Learn how to effectively use arrays in Java programming by discovering how to group data into arrays and exploring common methods and properties for working with them. Techniques for manipulating and optimizing arrays in real-world applications will also be examined.

Learn about String, a crucial data type in Java, and discover its many built-in methods and operations. Explore String and StringBuilder, understanding their basic methods and how to use strings effectively in Java.

Nel corso delle lezioni seguenti, verranno approfonditi i meccanismi interni di Java e saranno illustrate metodologie ottimizzate per lavorare con il linguaggio. Ciò comporterà l'esplorazione delle operazioni di Java a livello di computer e l'adozione delle migliori pratiche per utilizzare in modo efficiente i concetti già noti.

Hai già incontrato i metodi e ora finalmente comprenderai cosa sono effettivamente, come creare i tuoi metodi e come lavorare con essi. Imparerai a restituire i valori desiderati dai metodi e a migliorare significativamente la qualità e la logica del tuo codice.

Preparati a immergerti nel mondo di String e a scoprire di più sul suo funzionamento interno e sui suoi metodi. Esploreremo le caratteristiche interessanti offerte da String, inclusa la possibilità di personalizzare il metodo "toString", suddividere le stringhe in sottostringhe e utilizzare gli indici per un recupero efficiente dei dati. Iniziamo questo entusiasmante percorso per ampliare la nostra conoscenza della manipolazione delle stringhe!

In questa sezione, imparerai a creare le tue classi e i relativi oggetti. Sarai in grado di utilizzare i metodi di una classe all'interno di un'altra e di stabilire relazioni tra di esse. Preparati a scoprire molti concetti interessanti e ad approfondire la programmazione OOP!

In questa sezione, continueremo il nostro studio delle classi. Esploreremo un utilizzo più avanzato degli oggetti di classe e approfondiremo i modificatori di accesso e il loro utilizzo efficace. Analizzeremo inoltre getter e setter, in quanto considerati best practice nella programmazione.

Finalmente, possiamo iniziare a studiare la programmazione orientata agli oggetti (OOP) in Java. Sarà impegnativo, ma sono certo che avrai successo! In questa sezione tratteremo tutti i principi della OOP e spiegheremo perché la OOP è importante. Imparerai come ereditare classi, sovraccaricare e sovrascrivere metodi, incapsulare dati da altre classi e lavorare con l'astrazione. Inoltre, rafforzerai tutti questi concetti teorici con esercizi pratici, lavorando su assegnazioni nel tuo IDE. Acquisirai una vasta conoscenza, sia pratica che teorica, quindi iniziamo!

Nella sezione precedente, abbiamo concluso che tutta la Programmazione Orientata agli Oggetti si basa principalmente sull'astrazione. Tuttavia, una classe astratta presenta una limitazione significativa: è possibile ereditare solo da una classe astratta. Ma cosa succede se abbiamo bisogno di più? Le interfacce vengono in nostro aiuto. In questa sezione, apprenderai che cos'è un'interfaccia, perché è necessaria, come utilizzarla correttamente e continuerai a esercitarti con la Programmazione Orientata agli Oggetti. Preparati a diventare un professionista!

Discover the concept of lists and explore the most commonly used types in Java. Learn how to create, modify, and manage lists efficiently. Understand their internal structure and discover when to use ArrayList vs. LinkedList based on performance. Implement your own singly linked list and reinforce key concepts through practical coding challenges.

Learn about data structures that are not as commonly used but are still valuable. Data structures like Set, Stack, Queue, and Deque will help you better understand how Java works and their various applications in databases.

Learn about key-value pair-based data retrieval, enabling the creation of structures similar to databases. Discovery of concepts like hashcode and exploration of data structures such as HashMap and HashSet are also included.

Learn to use enum for defining a fixed set of constants and explore the Stream API to process, filter, and transform data efficiently.

Let's talk about types of testing and which testing methods developers use. You will learn about the stages an application goes through before being delivered to the client and the specific tests you will need to write.

In this section, we're going to dive into unit testing — you'll get the rundown on its structure in Java and the ins and outs of crafting them the right way. Setting up your IDE, importing necessary libraries, and lots of hands-on practice.

In this section, we will enhance our coding skills by dealing with errors that can also be caught in unit tests. When testing an application, you may come across various errors, and sometimes they should be turned into exceptions. I will explain how to catch exceptions in your code, test them, and handle them properly.

This section will delve into the foundational concepts of multithreading in Java, focusing on the creation and management of threads, and the use of synchronization techniques to avoid conflicts. You’ll also learn how to utilize essential keywords and methods to ensure the accurate and reliable execution of multithreaded programs, providing a solid understanding of how to handle concurrency effectively in your applications.

This section explores synchronized collections in Java, explaining their purpose and the common concurrency issues they are designed to solve. You’ll gain insights into how these collections work, why they are essential in multithreaded environments, and how they help ensure safe and consistent data manipulation when multiple threads access shared resources.

This section covers high-level synchronization mechanisms in Java, such as the use of Lock and Condition, semaphores, barriers, atomic variables, and thread pooling with Executors. Each topic is paired with practical exercises designed to reinforce your understanding and help you apply the theoretical knowledge to real-world scenarios.

This section explores fundamental multithreaded programming patterns and practices such as Producer-Consumer, Fork/Join, ThreadLocal, and asynchronous programming with CompletableFuture. You'll work through examples and see the practical outcomes of these approaches, gaining hands-on experience that will enable you to apply these techniques effectively in real-world applications.

Discover how Stream API revolutionizes data processing in Java with its expressive and functional approach. Explore its architecture, principles, and key functional features to write concise and efficient code.

Learn about various intermediate operations available in the Stream API that allow you to manipulate and process data in a functional style. These operations, such as filtering, transforming, and sorting, enable you to efficiently work with collections and perform tasks like removing duplicates, limiting results, or handling nested structures. Each operation can be combined to create powerful data pipelines, making your code more concise and readable.

Learn about various terminal operations available in the Stream API that allow you to process and retrieve data efficiently. These operations, such as collecting, reducing, and counting, enable you to aggregate results, find specific elements, or perform side effects like printing or writing to a file. Understanding these operations helps you efficiently handle data processing tasks while keeping your code concise and expressive.

Discover how to apply Stream API in real-world scenarios, improving code readability and efficiency. Learn how to refactor existing code, analyze performance trade-offs, and handle exceptions properly. Will help you write cleaner and more maintainable Java code using Stream API.
