Congratulations!

You have passed the whole course on multithreading and know a lot more about it already! But this is still not the end!

You have learned one of the most complex technologies in all programming languages. It may not have been easy for you, but you did it!

Let's go through the whole course and remember what you have learned.

Section 1: Multithreading Basics

In this section, you learned what multithreading is and how it differs from single-threaded execution.

Multithreading allows you to execute multiple tasks at the same time, which increases the performance and responsiveness of applications.

You learned the basic aspects of threading in Java, including creating and managing threads.

Special attention was paid to synchronization models, which are necessary to ensure threads execute correctly and avoid conflicts when accessing shared resources.

You also looked at performance issues and atomicity of operations, which is important for creating safe and efficient code.

Benefit

These basics are the foundation for understanding the more advanced concepts of multithreading and concurrency. They enable you to effectively use threads to perform parallel tasks and manage resources in a multithreaded environment.

Section 2: Synchronized Collections

Here you explored collections that provide security for access from multiple threads.

You learned about different types of synchronized collections, such as ConcurrentMap and CopyOnWriteArrayList, which provide mechanisms for secure access and modification of data.

An important aspect was learning about parallel streams through the Stream API, which allows you to efficiently process large amounts of data in multi-threaded mode.

You also worked with BlockingQueue, which is used to coordinate tasks between threads.

Benefit

Knowing synchronized collections allows you to safely work with data in multi-threaded applications, avoiding typical problems such as races and locks.

Section 3: Higher-level synchronization mechanisms

In this section, you learned more advanced synchronization mechanisms, such as Lock and Condition, which offer more control over threads than traditional synchronized blocks.

You also learned about Semaphore and CyclicBarrier, which are used to coordinate multiple threads.

Atomic variables provide a convenient means of performing operations on variables without the need for explicit synchronization.

The use of Executors and thread pools helps you manage groups of threads efficiently.

Benefit

This knowledge will help you create more complex and scalable multithreaded applications, manage threads efficiently, and synchronize their work.

Section 4: Multithreading Best Practices

Here you learned about design patterns, such as Producer-Consumer, and mechanisms, such as ForkJoinPool, that are used to accomplish tasks that require partitioning into subtasks.

You have explored the use of ThreadLocal to store thread-specific data.

Fundamentals of Asynchronous Programming and CompletableFuture allowed you to master creating asynchronous tasks and combining them.

Benefit

This knowledge provides you with a set of tools and patterns to develop efficient multithreaded applications, improving their performance and scalability. You will be able to apply best practices to solve complex problems and optimize your threading experience.

What's next?

I recommend using all this knowledge for your projects, even if you don't have it, just start and you will see how much easier it will be when you know more about multithreading!

Also be sure not to forget to study multithreading, as here we have considered the main technologies that will help you at the start and learning new ones will be given much easier!

You are much closer to becoming a Java developer! Go ahead and only go ahead!
