Java course

The Java Syntax quest can be mastered even by someone who has never programmed before. You'll learn about classes, objects, methods, variables, data types, arrays, conditional operators, and loops. You'll take a quick look at collections and OOP, and you'll also start working in IntelliJ IDEA, a development environment used by programmers all over the world!
The Java Core quest is intended for those who have already received basic Java training (by completing the Java Syntax quest). Here you have to pass 10 fascinating levels where you will learn the basics of OOP, get acquainted with streams, serialization, and method overloading, and you'll learn a lot about interfaces and multiple inheritance.
The Java Multithreading quest introduces CodeGym students to multithreading. On Level 10, you'll study the organization of Object, String, and inner classes. You will learn how to create and stop threads, what deadlock is, and what the wait, notify, and notifyAll methods do. You'll gain experience working with jsoup and Swing, and learn about autopacking.
The Java Collections quest is dedicated to an in-depth study of Java collections and more. We'll talk about working with files and archives, as well as design patterns and how to use them. You'll get experience with JSON, Guava, Apache Commons Collections, and JUnit. You'll learn more about garbage collection in Java, and get to know Git, RMI, DymamicProxy and JavaScript.
