Step 7: Click on New
Under System variables, look for the New button and click on it. This will open a new window where you can create a new System variable.
Step 8: Enter Variable Name
In the new window, under Variable Name, enter JAVA_HOME. This should be in block letters, and ensure that you do not include any spaces.
Step 9: Enter Variable Value
Under Variable Value, paste the Java JDK path that you copied in Step 3. Ensure that the path does not have any spaces.
Step 10: Edit Path Variable
Under System variables, locate the Path variable and click on the Edit button. This should open a new window where you can edit the Path variable.
Step 11: Add Java JDK Path
In the new window, look for the New button and click on it. Paste the Java JDK path that you copied in Step 3. Ensure that you separate it from the other paths with a semi-colon (;).
Step 12: Save Changes
Once you have added the Java JDK path to the Path variable, click on the OK button to save the changes. You may need to restart your computer for the changes to take effect.
Explanation
Now that we have gone through the 12 steps on how to setup Java_home in Windows, let’s dive into the explanation behind each step.

Step 8 involves entering the Variable Name, which should be written in block letters as JAVA_HOME.
Step 9 involves entering the Variable Value, which should be the Java JDK path that you copied in Step 3.
Step 10 involves editing the Path variable so that it includes the Java JDK path.
Step 11 involves adding the Java JDK path to the Path variable, with a semi-colon separating it from the other paths.
Step 12 involves saving the changes that you made to the Environmental Variables settings. You may need to restart your computer for the changes to take effect.
Tips and Tricks
Tip 1: Double-check the Java JDK version
Before you download and install the Java JDK, make sure that you have the correct version for your Windows. Having the wrong version can lead to problems during setup.
