In this short tutorial, we’re going to take a close look at how to install Java on Windows 10.
We’ll first start with a little insight into how to download Java. Then, we’ll explain how to install it on Windows 10. Then, we’re going to see how to properly set JAVA_HOME environment variable.
Lastly, we’ll highlight different ways to check Java and JDK versions on Windows 10.
So, let’s get started
Download Java for Windows 10
In this section, we’re going to cover in-depth all the steps required to download Java for Windows 10.
As a matter of fact, downloading Java is a piece of cake. It’s just a matter of a few clicks and simple one-time steps.
First, we need to visit the official Oracle download page and choose the right release for the Java SE Platform.
At this point in time, the latest version is Java SE 16.0.1.
Secondarily, we need to click on the JDK Download button:
Bear in mind that Oracle has dropped the support for 32 bit systems. As a result, we can use Java SE only in 64 bit machines.
For instance, Oracle offers two options to install Java on Windows: through a .zip file and a .exe executable file.
Next up, let’s choose the Windows x64 Installer option:
Then, we have to accept the Oracle Technology Network License Agreement for Oracle Java SE to proceed to the next step:
Lastly, a simple click on the download button will do the job.
Install Java on Windows 10
Now that we download Java for Windows 10, let’s see how to install it. Basically, the process of installing Java on Windows 10 is pretty easy and simple.
In general, we don’t need to change anything during the installation, we can go with the default settings and follow the suggested instructions.
Firstly, we need to double click on the downloaded installer file to start the installation process:
Secondarily, we click Next to continue:
Note that, “C:\Program Files\Java\” is the default Java installation folder! However, we can always change it if we want that.
Then, we keep hitting Next until the installation is complete:
Finally, we close the installer window once the installation of JDK is complete on our Windows 10.
Now that we known how to install Java on Windows 10, it’s time to proceed to the next step.
In this short chapter, we’re going to dive deep into how to set JAVA_HOME environment variable on Windows 10. Please note that, JAVA_HOME should point to a JDK folder not JRE.
The basic idea behind setting the Java Path is to make all the Java commands like java, javac… accessible from everywhere. That way, we can run Java programs from anywhere.
First, let’s open the Advanced System Settings. To do that, we just need to press Windows key + Pause Key. Alternatively, we can type View advanced system settings in the search box.
Once the System Properties window is opened, we click on Environment Variables:
Secondarily, we click on New button to create a new System variable with JAVA_HOME as name and the path to the JDK directory as value:
As we can see, the JAVA_HOME environment variable points to the JDK folder which C:\Program Files\Java\jdk-16.0.1 is in our case.
Next, we need to update the Path variable by adding a new entry for %JAVA_HOME\bin%:
Finally, we can click OK to save and apply the changes.
That’s all we can say about downloading and installing java on windows 10. Now, we’re ready to write our first Java program.
There are multiple ways that we can use to check Java version on Windows 10. Basically, when we say Java version, we mean JRE version.
The most obvious and basic way is to use the terminal. Firstly, press Win+R and type cmd to open the Command Prompt. After that, type java -version and press Enter:
C:\Users\Asus>java -version java version "16.0.1" 2021-04-20 Java(TM) SE Runtime Environment (build 16.0.1+9-24) Java HotSpot(TM) 64-Bit Server VM (build 16.0.1+9-24, mixed mode, sharing) C:\Users\Asus>
The output means that Java is properly installed on our operating system.
Alternatively, we can type “Java” in the search box and click on “About Java”:
Please bear in mind that multiple versions of JDK can be installed on the same on Windows 10 machine. So, it’s important to make sure the JAVA_HOME environment variable points to the right JDK release.
Let’s open a new command prompt and type:
C:\Users\Asus>echo %JAVA_HOME% C:\Program Files\Java\jdk-16.0.1 C:\Users\Asus>
As show above, the environment variable JAVA_HOME points to the directory of the lastest JDK version.
We can also use javac -version to verify the version of the installed JDK:
C:\Users\Asus>javac -version javac 16.0.1 C:\Users\Asus>
Another important thing to note is that the JDK version can be different from the JRE version on the same machine.
Please keep in mind that we need always to check for new Java updates and install them to keep our machines up-to-date with the latest releases.
