Hi there again, My name is Marius from AlefTav Coding, and this is the third lecture of my course, Java for Beginners.
In this lecture you will learn how to download and install the tools needed for writing Java programs.
In order to write a Java program, you need two things:
- The Java Development Kit (JDK)
- A source code editor in which you type your java programs. The term used for the code editor is, Integrated Development Environment or in short, IDE.
The JDK is needed to compile and run Java programs. While the IDE allows you to write the programs. I use IntelliJ IDEA as my preferred IDE. The two other major Java IDE's are Eclipse and Netbeans.
In addition to the JDK and IDE, you need an internet connection with a browser to download these two tools. I am using Google Chrome.
To download the JDK, go to Google, then type JDK download, and select Java SE development kit downloads. You will be directed to the Oracle downloads page. Accept the licence agreement for the latest development kit, and download the JDK for your particular machine. Mine is a windows x64 machine. So I selected the JDK for Windows x64 option. This download process takes a few minutes to complete.
If you don't know which Java version to download, then if you have Windows 10 installed, click on Start, then in the Search window type the words, This PC and click on the This PC option. Right click on This PC and select Properties. The System type will show your processor type.
Next, to download IntelliJ, go back to Google and type in the search bar, download IntelliJ IDEA and press enter for the download page. I chose Windows and the Community edition. Community is the free version of IntelliJ. This download process also takes a while to complete.
On Windows the JDK and IntelliJ will be downloaded to the default downloads folder. Next click on the JDK file to install it on your computer. Follow the directions by clicking next.
Afterwards click on the IntelliJ file to install it on your device. Again, follow the directions by clicking next. I want a desktop shortcut so I select the 64-bit launcher checkbox option, and for create associations I select the .java checkbox. All java files will automatically by opened in IntelliJ. Click install. Install will also take a while to complete, but when it is finished, select the checkbox, Run IntelliJ IDEA and click finish.
IntelliJ will now start up. The first time you run IntelliJ you may need to customise the IDE. For our purposes, click skip all and set defaults. You will shortly see the Welcome to IntelliJ menu.
In this lecture you learned how to download and install the development tools in order to write your first Java program in the next lecture.
This is Marius from AlefTav Coding. See you in the next lecture.
