The video shows why Java is absolutely suitable as a language for learning programming and what advantages it offers.

Java for beginners - 1.3 What is the best way to learn programming?

This video is generally dedicated to the topic of "learning to program". How can you learn a language? What methods and approaches are there? And since the course can only be the beginning: What happens afterwards?

Java for beginners - 1.4 Where can I find help?

We show you where you can find help, both during and after the course, in addition to the usual channels.

Java for beginners - 1.5 Working with the course

How you work with the course is up to you. However, the tips presented here are based on experience and show you how to get the most out of the content.

The beginning

Java for beginners - 2.1 Understanding Java bytecode

Even before we start programming: how does Java work? What role does the so-called bytecode play? What is bytecode anyway? How does C++, for example, differ in this respect?

Java for beginners - 2.2 Installing the JDK

Installing the Java Development Kit (JDK) is a mandatory exercise for developing with Java. This is the only way to follow the rest of the course. We will show you how to do this here.

Java for beginners - Install 2.3 IDE

A development environment (IDE) goes far beyond the function of a "normal" text editor. It includes the editor, color highlighting of syntax, error messages, debugger, logic for translating programs, etc. We work with IntelliJ IDEA in the course and show the first steps with the program.

A first date

Java for beginners - 3.1 Your first program

You write your first program, create your first variable and output its content. Also a few words about the organization of the source code.

Java for beginners - 3.2 The Java compiler (javac) and the JRE (java)

How is Java translated/compiled? Work with the javac. Also: Bytecode/.class files and executing Java programs.

Java for beginners - 3.3 Debugging

How can you find errors in software? A few words about syntax errors and how to find logical errors with a debugger.
