Running Java 8 from C:\Program Files (x86)\Java\jre1.8.0_361

Introduction

As an experienced developer, you have been tasked with teaching a beginner developer how to run Java 8 from the directory "C:\Program Files (x86)\Java\jre1.8.0_361". In this article, we will guide the beginner through the process step by step, providing the necessary code and explanations along the way.

Steps to Run Java 8

Step Description
Step 1 Set up Java Development Kit (JDK)
Step 2 Set up Java Runtime Environment (JRE)
Step 3 Configure the system PATH variable
Step 4 Verify the Java installation

Step 1: Set up Java Development Kit (JDK)

To begin, we need to install the Java Development Kit (JDK). Follow these steps:

  1. Visit the Oracle website and download the JDK installer for Java 8.
  2. Run the installer and follow the prompts to complete the installation.
  3. Make note of the JDK installation directory.

Step 2: Set up Java Runtime Environment (JRE)

Next, we need to set up the Java Runtime Environment (JRE). Here's what you need to do:

  1. Visit the Oracle website and download the JRE installer for Java 8.
  2. Run the installer and follow the prompts to complete the installation.
  3. Make note of the JRE installation directory.

Step 3: Configure the system PATH variable

To run Java from the command line, we need to configure the system PATH variable. Follow these instructions:

  1. Open the Control Panel and go to System.
  2. Click on "Advanced system settings" on the left-hand side.
  3. In the System Properties window, click on the "Environment Variables" button.
  4. In the "System variables" section, locate the "Path" variable and click on "Edit".
  5. Add the following entries at the beginning of the "Variable value" field:
    C:\Program Files (x86)\Java\jre1.8.0_361\bin;
C:\Program Files\Java\jdk1.8.0_361\bin;
  6. Click "OK" to save the changes.

Step 4: Verify the Java installation

To ensure that Java 8 is running properly, follow these steps:

  1. Open the command prompt.
  2. Type the following command and press Enter:
    java -version
    This will display the version of Java installed on your system.
  3. Type the following command and press Enter:
    javac -version
    This will display the version of the Java compiler installed on your system.

Conclusion

By following these steps, the beginner developer should now be able to run Java 8 from the directory "C:\Program Files (x86)\Java\jre1.8.0_361". The configuration of the JDK, JRE, and PATH variable ensures that the Java runtime environment is accessible from the command line. Verifying the Java installation confirms that the setup was successful.

Note: It is important to always use the appropriate version of Java for your development needs.
