Change your PATH variable so that it has the location of the jdk5/bin directory:
- Start -> Control Panel -> System -> Advanced
- Click on Environment Variables, under System Variables, find PATH, and click on it.
- In the Edit windows, modify PATH by adding the location of your jdk5/bin directory to the beginning. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the directory as the value.
- Close the window.
- Reopen Command prompt window, and run
java -version

In the command shell:
set JAVA_HOME=C:\jdk1.6.0u24
set PATH=%JAVA_HOME%\bin;%PATH%
That will temporarily set up the environment in the command shell. Maven, Ant, etc. will pick up on your new version of Java without having to go to the Control Panel repeatedly.
Tools like Eclipse should be able to select which JDK to use in their own configuration tools for use within their environments.

when latest version is installed in system it automatically set javapath in environment variable like "C:\ProgramData\Oracle\java\javapath".
Remove this from environment variables.

This suggestion may seem obvious, but I urge you to carefully consider this advice.
I have encountered this issue before, and frequently, it has been due to an overlooked entry within the long list of items making up the Windows Path. It is often an path entry where it is not immediately obvious that any of the java executables (javaw.exe, javaw.exe or javaws.exe) may reside. A common culprit is C:\ProgramData\Oracle\Java\javapath
You will therefore need to push upwards, your desired java/bin path above these. If in doubt, push it right to the top!
In the unlikely event that this does not work, then try making changes from within the java admin console (Control Panel --> Java --> Java tab --> View Button).

How to Change Java Versions in Windows (up to Java 25)
June 11, 2025 - Some programs, such as Eclipse, define the Java version in a separate configuration file (for Eclipse, for example, this is the entry "-vm" in the eclipse.ini file). The Java installers create various environment variables, which you need to clean up first (see below). The fastest way to change the environment variables is to press the Windows key and type "env" – Windows then offers "Edit the system environment variables" as a search result:

r/javahelp on Reddit: How do I switch between Java versions?
March 20, 2023 -
So, I have two different versions of Java in my system, 8 and 16. Depending on the project, I need to switch between the two. Right now, I need to use 16, but when I run java -version I see, I'm still using "1.8.0_202".
I have changed my JAVA_HOME variable to point to the location of Java 16. Do I need to uninstall Java 8 in order to use Java 16? I'd rather not do that.

Sdkman is what you want. You can install lots of different flavours and versions of Java and rapidly switch between them with 'sdk default java 8/11/17/whatever'. It updates all the paths and tools from that command

There is a useful tool on Linux/Mac called jenv that allows you to set the jvm to use for a directory and its subdirectories. Someone has created a port of that to windows here: https://github.com/FelixSelter/JEnv-for-Windows If you're going to be using a lot of different jvms it would be worth looking into.
