Why Java is so important nowadays and what you will learn in this course. This course is intended for beginners and gives you a first glimpse view in the Java programming language. We will work with an IDE and get our first little programs running.
We download the requirements of this course. This is just a Windows installation but other operating systems should work similar.
We are installing NetBeans with the underlying Java JDK.
What has been installed? Differences between a JDK and a JRE.
A "Hello World"-program is created and started.
Maybe this was to fast for you. So I go over the process what exactly happened and how our program was executed.
Variables are placeholders for values.
Repetition and deepening of the variable usage.
This is the program we have build so far.
If-statements check if something is true or false and are able to execute different code blocks according to the check.
Maybe the lecture about the if-statements was to fast for you. So you get a chance repeating the facts and enlarging your knowledge in this lecture.
If something has to be repeated, the while loop is the simplest way to do that.
The While-loop as flow chart and the variation of the While-loop: The Do-While-loop.
If something has to be repeated an already known number of times, the for-loop is right for you.
This is the program we have build so far.
This is the program we have build so far.
This is our complete program.
This is a mini-course about the programming language Java. You will learn about how to install the NetBeans IDE together with Java, create your first project and start this project. The course will introduce you into commands, variables, conditional statements, methods, classes, inheritance and visibility modifiers.
This is a very short course about the Java language. It will teach the very basics. It is create for those who need a quick start maybe because they have to solve some exercise questions they received by their teachers as homework. Or it is intended for people who need a first feeling what Java is.
