What’s Needed
Before we dive into the process of setting the Java 11 path on Windows 10, there are a few things you will need. Let’s take a look at what you’ll need before starting:
1. Java Development Kit (JDK) version 11: You will need to download and install the JDK 11 on your Windows 10 computer. The JDK can be downloaded from the official Oracle website.
2. Administrative privileges: To make changes to the system environment variables, you will need administrative privileges on your Windows 10 computer.
What Requires Your Focus?
When setting the Java 11 path on Windows 10, there are a few key areas that require your focus. These areas include:
1. System Environment Variables: In order for your computer to locate the Java Development Kit (JDK), you will need to modify the system environment variables.
2. PATH Variable: The PATH variable in the system environment variables is where you will add the path to the JDK 11 installation directory. This will allow your computer to locate the necessary Java files when compiling and running Java code.
3. Verify Installation: After setting the Java 11 path, it’s important to verify that the installation was successful. You can do this by checking the Java version in the command prompt.
Next, we will explore different methods to set the Java 11 path on Windows 10.
