Below are the steps to install Java 21 JDK on Windows 11 PC.

Note: We will be installing Oracle OpenJDK Java 21 Standard Edition (SE)

Go to the official Oracle OpenJDK Download page for Java 21 - https://jdk.java.net/java-se-ri/21
Download the setup: Windows 11 x64 Java Development Kit. This will download a zip file - openjdk-21_windows-x64_bin.zip
Now create a Java-21 folder under C:\Program Files and extract the jdk-21 zip file in it.

Open Command Prompt and try out the java --version command.

java --version
