Java from Zero to PRO: TOP YouTube Channels and Courses 2024

Java is not dying: why should you learn the language in 2024?

Java is like a good old hammer: not the trendiest tool, but you can't do without it. While everyone is running around with Rust and Go, Java quietly works in 90% of banking systems, powers Android apps, and the backends of giants like Netflix and Amazon. And yes, Java developer salaries remain among the highest on the market.

The problem is different: learning Java from boring textbooks is a drag. You'll close your IDE on the fifth page about "method overloading." It's a different story with YouTube channels and courses on Java, where they show you (in the console) how multithreading works or how to build your first microservice.

At PythonLib, we've put together a top selection of Java resources that covers all stages: from "what is a variable" to "I'm writing production code." Let's go!

How to choose the perfect Java course on YouTube?

Before diving into the list, remember three rules:

\n
• Practice > Theory. If the lecturer explains a concept for more than 10 minutes without a single line of code — close the tab.
\n
• Relevance. Java 21 is already out, but they're still showing you Java 8 with outdated patterns? Not good.
\n
• A project for your portfolio. A good course necessarily includes writing a real application (Todo, weather service, banking API).
\n

Our selection takes these criteria into account. Choose according to your level.

TOP-10 YouTube channels and courses on Java

1. Java for absolute beginners: JavaRush

Don't confuse it with the website of the same name. The YouTube channel JavaRush is a goldmine for those who write "public static void" and don't understand why it's needed. Short videos, a lively host, no fluff.

An example of how they explain loops:

// Simple for loop\nfor (int i = 0; i < 5; i++) {\n    System.out.println("Iteration number: " + i);\n}\n\n// Output:\n// Iteration number: 0\n// Iteration number: 1\n// Iteration number: 2\n// Iteration number: 3\n// Iteration number: 4

The channel literally leads you by the hand from syntax to OOP. We recommend it for learning Java from scratch.

2. Advanced level: Senior Java Developer

If you already know the difference between ArrayList and LinkedList, but want to dig deeper — this is for you. The channel Senior Java Developer covers multithreading, garbage collection, design patterns, and Stream API tricks.

An example of working with CompletableFuture (asynchrony):

import java.util.concurrent.CompletableFuture;\n\npublic class AsyncExample {\n    public static void main(String[] args) {\n        CompletableFuture.supplyAsync(() -> {\n            try {\n                Thread.sleep(1000);\n            } catch (InterruptedException e) {\n                e.printStackTrace();\n            }\n            return "Result";\n        }).thenAccept(System.out::println);\n\n        System.out.println("Main thread is not blocked!");\n    }\n}

An ideal option for those who want to take Java courses for professionals.

3. Spring Boot from scratch: Amigoscode

An English-language channel, but with clear diction and subtitles. Amigoscode is a must-have for anyone who wants to master Spring Boot. The "Spring Boot Full Stack" course lasts 8 hours, but you'll breeze through it.

Micro-project: REST API in 5 minutes:

@RestController\npublic class GreetingController {\n    \n    @GetMapping("/hello")\n    public String sayHello(@RequestParam(value = "name", defaultValue = "World") String name) {\n        return String.format("Hello, %s!", name);\n    }\n}

After this video, you'll be able to write your first backend for a To-Do list. An excellent Java Spring course.
