It is possible to install multiple JDK versions on the same PC, but it is recommended to install Java on Windows 10 with the latest version. ## How to Install Java for Windows 10 (64-bit) Following are the steps to install Java in Windows 10, for the JDK 8 free download for 32-bit or JDK 8 download for Windows 64-bit, and installation. **Step 1)** Go to this [link](https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html). Click on JDK Download for the Java JDK 8 download. [](https://www.guru99.com/images/download-java-jdk-8.png) **Step 2)** Next: 1. Accept the License Agreement. 2. Download Java 8 JDK for your version, 32-bit or 64-bit. [](https://www.guru99.com/images/2/javainstall-2.png) **Step 3)** When you click on the installation link, the popup will open. Click on “I reviewed and accept the Oracle Technology Network License Agreement for Oracle Java SE Development Kit” and you will be redirected to the login page. If you do not have an Oracle account, you can easily sign up by adding your basic details.

The CLASSPATH variable gives the location of the library files. Let us look into the steps to set the PATH and CLASSPATH. **Step 1)** Right-click on My Computer and select Properties. [](https://www.guru99.com/images/java/111417%5F1107%5FJava25.png) **Step 2)** Click on Advanced system settings. [](https://www.guru99.com/images/2/java-install-20.png) **Step 3)** Click on Environment [Variables to set](https://www.guru99.com/java-variables.html) the Java runtime environment. [](https://www.guru99.com/images/java/111417%5F1107%5FJava27.png) **Step 4)** Click on the New button of User variables. [](https://www.guru99.com/images/java/1912211%5Finstall%5Fjavaimage9.jpg) **Step 5)** Type PATH in the Variable name. [](https://www.guru99.com/images/java/111417%5F1107%5FJava29.png) **Step 6)** Copy the path of the bin folder, which is installed in the JDK folder. [](https://www.guru99.com/images/2/java-install-21.png) **Step 7)** Paste the path of the bin folder in the Variable value. Click on the OK button. [](https://www.guru99.com/images/2/java-install-22.png) **Note:** In case you already have a PATH variable created on your PC, edit the PATH variable to: PATH = \bin;%PATH%; Here, %PATH% appends the existing path variable to our new value. **Step 8)** You can follow a similar process to set the CLASSPATH. [](https://www.guru99.com/images/2/java-install-23.png) **Note:** In case your Java installation does not work after installation, change the CLASSPATH to: CLASSPATH = \lib\tools.jar; **Step 9)** Click on the OK button. [](https://www.guru99.com/images/2/java-install-24.png) **Step 10)** Go to the command prompt and type the javac command. If you see a screen like the one below, Java is installed.

AI assistants can guide JDK installation, generate correct PATH and CLASSPATH values, and troubleshoot errors. However, you still apply the configuration changes on your own system and verify them yourself. 🧠 Do I need Java installed to run AI or big-data tools? It depends. Several big-data and AI frameworks, such as Hadoop and Spark, run on the JVM and require Java. Many Python-based machine learning tools do not need a JDK installed. 📦 What is the difference between JDK, JRE, and JVM? The JDK is the full development kit for writing and compiling Java. The JRE runs Java programs. The JVM is the engine inside the JRE that executes compiled Java bytecode. 💻 How do I check if Java is installed on Windows? Open Command Prompt and type “java -version” or “javac -version”. If a version number appears, Java is installed and correctly added to your system PATH variable. #### Summarize this post with: ChatGPT Perplexity Grok Google AI **Stay Updated on AI** **Get Weekly AI Skills, Trends, Actionable Advice.** ##### Sign up for the newsletter Subscribe for Free You have successfully subscribed.
