How to Install Java in Windows 10, 7, 8.1, XP?

Have you started learning Java recently? Or do you require Java JDK for your Android project? Nonetheless, let us see how we can go head and install Java and write our first Hello world program today.


Before we start,
Let us see if you have already installed Java in your Laptop / PC. There might be a small chance you’ve already installed Java or your brother might have installed it for his projects 👻

Click on Start, Type
CMD
in your search bar. Now when the Command Prompt opens,

just type java -version

If you have Java installed already, you will be informed about the current version of Java installed.

If you get a message saying java is not recognized, Let us now install Java 🚀

Let us install Java and write our Hello World program in 3 Steps.

1. Installing Java JDK:

Install which ever JDK do you want to install. It is preferred you install the latest JDK version but let us see how to install Java JDK 8 which is the LTS (Long Term Support) Version of Java JDK.

Click on JDK Download.

Hint: If you are using Windows, and confused if your architecture is x64 or x84, then Open the Start menu , type msinfo32 into the search box, and press Enter.

In System Summary on the left side, look to see if your System Type on the right side is either a x64-based PC or a x86-based PC

I recommend to go with the default installation process and click on Next for all the steps.

Click on Close and complete installation. Congratulations! You’ve successfully completed Step 1: Installing Java JDK🎉🥳

2. Configuring Environment Variables to change the JDK PATH :

After you go to Environment Variables,

Click on Path under User Variables section. Then select New…

Now Minimize the Environment Variables screen for a second. Let’s go to our C folder in our PC.

Copy the path once you go into the Bin folder. For me, the Path was: C:\Program Files\Java\jdk-13.0.1\bin

Now copy your complete path and then open the New
option in Environment Variables once again. We will create two variables: PATH and CLASSPATH

i. Give the variable name exactly as: PATH
Paste the URL you have copied earlier from your bin folder and paste it in the Variable value

Note (Follow this step if and only if you get an error): If you get an error saying you already have a variable called PATH existing,

Edit that Variable’s Path:

PATH = <JDK installation directory>\bin;%PATH%;

Here, %PATH% means previous PATH’s value.

i.e, if you already have a PATH variable that has value C:\Program Files\flutter ,

Edit that variable as: C:\Program Files\Java\jdk-13.0.1\bin;C:\Program Files\flutter;

Press Ok. Now let’s set few more User Variables similarly.

ii. You can follow a similar process to set CLASSPATH.

Press Ok and close the Application Window.

3. Final check

Now open Command Prompt again by searching for CMD in Run

Enter the command java -version

If you get the above result, then congratulations! You have successfully installed and configured Java JDK. Take a break and Celebrate 🎉✨

Let us look how we can write Java Programs and run them in further articles!
