To change the JDK version number, you can follow these steps:

  1. Download and install the new JDK version: Download and install the desired new version of the JDK from the official website or other reputable sources. Make sure to follow the correct steps during the installation process.
  2. To set up environment variables, open the Control Panel on your computer, select “System” or “Advanced System Settings,” and then click on “Environment Variables.” In the System Variables or User Variables section, locate the variable named JAVA_HOME. Change its value to the installation directory of the newly installed JDK. For example, if the new JDK version is installed in C:\Program Files\Java\jdk1.8.0_271, then change the value of JAVA_HOME to that path.
  3. Update system path: In the Environment Variables dialog box, locate the variable named Path and edit it by adding a semicolon (;) at the end of the variable value, followed by the bin directory path of the new JDK. For example, if the installation path of the new JDK version is C:\Program Files\Java\jdk1.8.0_271, change the value of Path to ${original path};C:\Program Files\Java\jdk1.8.0_271\bin.
  4. Check the version number: Open the command prompt, type in the command “java -version”, and verify if the displayed JDK version has been updated to the new version you selected.

Please be aware that these steps may vary depending on the operating system and specific JDK version. Before making any changes, be sure to back up the system and relevant files in case of unexpected circumstances.
