How to Install Java in Windows 10
Installing Java on Windows 10 is really easy, just follow the steps as follows:
Java Download for Windows 10
Java Windows 10 installation steps
Java on Windows 10 Version Check
Download and Install Java IDE
First step is to download java installation files from Oracle’s website. Java 9 is the latest version, so go to this link and accept the license agreement. Then click on the download link for windows as shown in below image and save the file.
Note: If you are trying to install Java 8 or earlier, then you need to know whether your Windows 10 is 32-bit or 64-bit. It’s because there are two different installers for Windows as seen in this link for Java 8 binaries.
If your Windows 10 is 32-bit OS then download
Windows x86
exe file, else download Windows x64
exe file. If you are not sure of your Windows version, you can easily check it in
Settings > System Settings > About
.Next step is to run the downloaded java installer executable file. Just double click on it and follow the steps. Most of the time you don’t need to check anything and go with default selection, below are images from my installation screens. They might differ a little bit based on your java version installation but mostly it’s the same as usual.
Finally, we have to check if java is installed properly or not. We can do that by using
java -version
command in command prompt, as shown in below image.Note: In older java versions and other windows operating systems, you need to set up two environment variables to get it working.
Go to
System Properties (Right Click on My Computer and select Properties) > Advanced > Environment Variables
.In the popup window, System variables section, click on New button and add a variable with the following details:
Name: JAVA_HOME
Value: C:Program FilesJavajdk1.6.0_25
After this, you need to edit the Path variable already present there. Just select the Path variable and click on Edit button. In the popup window value section, go to the end and add the following
;C:Program FilesJavajdk1.6.0_25bin
(The colon is used as a delimiter, so don’t miss that!)Now your setup is done and you can check it by opening a command prompt and running command
java - version
. In Windows 10 and Java 9, we don’t need to do these manually. Java installer takes care of that and you can check environment variable Path value, as shown in below image. Note that we don’t need to set the JAVA_HOME variable.
This is an optional step but highly recommended. If you want to get things done easily, you should install either Eclipse, Intellij Idea or NetBeans IDE that helps a lot in development of java programs. Just download and install it with executable file, they are straight forward.

That’s all for downloading and installing java on windows 10. Let me know if you face any issue in setting up the environment.
What’s after installing Java
Now you are ready to learn java programming, go through the articles on core java tutorial and learn java programming step by step.
Note: A few years back, I made this video to install java 8 on windows 10. Steps are still almost the same so you can watch it to get more idea about it.
Also if you want to have multiple java versions and want to switch between them easily, then go through this short 2-minute video.
In the past we have talked about some online services that use the Java Runtime Environment (JRE) to run the server side application on the client side. While talking about them, I might have told you to allow JRE to run on the page. But if I would have been talking about the same services today, I will not ask you to grant those permissions. Rather I will ask you to completely disable or even uninstall Java from the computer.
Confused? Well, blame Java. Lately Java has been getting a lot of vulnerability issues and developers are reporting lot of security loopholes that are exploited by the hackers and malware authors to gain unauthorized access over computers all around the world.
The condition is so bad that the Feds in United States have asked users to completely disable or even uninstall Java from their system due to the security flaw. In recent events, a zero-day Java exploit compromised computers belonging to several Facebook engineers which could have compromised sensitive data. The bottom line is that Java has been the consistent target of attacks, and Oracle isn’t able to patch it in time leaving the vulnerabilities out in the open.
How long are we going to overlook these security issues for a handful of online Java based services? Well, I am not and if you too want to bring an end to it by uninstalling or disabling Java, let’s have a look at the steps to accomplish that.
We will show you the way to completely uninstall Java or just disable it. While the former is an extreme measure, it provides foolproof security from Java vulnerabilities. If you don’t want to completely uninstall Java, you may just disable it from the respective browsers.
Uninstalling Java Completely from Windows
To uninstall Java, open the Windows Control Panel and click on Uninstall a program link.
After the Program and Features window lists all the applications you have installed on your computer, search for Java and uninstall every Java installation and update that’s installed on your computer. If you are a developer and you have installed Java Development Kit (JDK), you might want to omit it. After the program uninstalls, reboot your computer.
You may also use an advanced uninstaller like Revo Uninstaller to do the above. In fact, it migh be a better way to do it.
Disabling Java
If you don’t want to completely uninstall Java and only want to disable it on your default browser, that can also be done. However, covering how to disable Java on all the browsers is beyond the scope of this article. We will see how it can be done on Firefox and Chrome, currently the top two browsers known to us.
Chrome users should write chrome://plugins in the Omnibar and press enter. In the plugin page look for Java and click on the Disable button next to it. Firefox users must open the add-on page by clicking the Firefox button and then disable the Java (TM) Platform plugin from the list. The procedure is quite similar for all the other browsers. You need to open the respective browser plugin page and disable Java from the list.
Conclusion
So that was how you can uninstall and disable Java in your browsers. If you have disabled it you will not be able to run some online apps that require Java Runtime Environment to function. If you have completely uninstalled Java then apart from the online tools that can’t run it, some of the native Windows programs that require JRE will not be able to function. Small price to pay for securing your computer against the deficiencies that Java brings along with it.
