We can’t help. You must research, troubleshoot, and solve this yourself. You or somebody with access to this Mac has installed something that needs Java. Some app that tries to start or to restart periodically. Some app dependent on Oracle Java. Which means you must find that app, and must then decide to either keep that app and install and properly configure the JDK, or to remove it all and that including the app.
The following command-line command will find most apps that use Java:
sudo find / -type f -iname *.jar
Launch Terminal.app, issue that command, and enter an admin password for the sudo.
There’s almost certainly also a launch agent here, which is what is attempting to invoke the Java-using app directly or maybe via a script.
Of course a fair amount of what’s posted for this error is “well, install Java”, which usually suppresses the error—if it’s the expected JDK, amd properly confiugred—and whatever here will then hopefully start doing whatever, and stop logging this annoying error. But if you’re not using this stuff, get rid of it. (Not the least of which because parts of recent Java can require a commercial license, and can require payments to Oracle, if not (re)configured to avoid using the part of the Java code that requires the commercial license.)
