Java Syntax
The Java Syntax quest was developed at the secret CodeGym center. It consists of 10 levels devoted to the fundamentals of the Java language. It can be mastered even by someone who has never programmed before. You will learn about classes, objects, methods, and variables. You will study basic data types, arrays, conditional statements, and loops. Take a quick look at collections and OOP basics (a serious study of these topics will begin in Quest 4), and start working in IntelliJ IDEA, a popular development environment used by programmers all over the world!
But most importantly, you will complete a lot of tasks. Tasks play a central role at CodeGym. And virtual mentors will help you deal with mistakes (Your solutions are checked instantly).
