Dear fedora users,
I want to generate randomly generated triangles from points as in
https://www.sanfoundry.com/java-program-compute-area-triangle-using-determin...
The java program compiles fine but executing it returns an error. I do not understand the error.

I had another program called Ulam (3n+1) conjecture, Or Collatz Conjecture and it also fails to run.

any suggestions as to why it does not run? Do I need to use oracle's java? does openjdk no longer work. Thank you in advance.

So there's the problem. You're compiling with 21, but running it with 17. You could try adding "--release 17" to the javac command when you compile or switch the default java to 21 using the alternatives command. Or directly specify the 17 compiler when you compile.

Is there a better way to avoid doing this, ie removing java 17 and forcing 21 ? or vice versa to avoid this. I had not encountered this before in previous versions of Fedora it just worked! Now I have to specify. What would be the best thing to do? and make it work correctly.

You could try removing 17 if nothing else depends on it. You could remove the rolling 21 release devel and install the 17 devel. You could switch the default java to 21/rolling using the alternatives command.

Transaction Summary ================================================================================ Remove 62 Packages
Freed space: 654 M Is this ok [y/N]:
I guess I will need to just use your advice and leave it as it is. I do not want to remove libreoffice. I use it. Thanks to all who have explained how to deal with this issue. I had not encountered it before but was afraid to ask.
Best Regards,
Antonio

You could still try the alternatives option. "alternatives --config java"

How would that work? It seems to me he has no version 17 compiler to go with the version 17 virtual machine. If he has a version 21 virtual machine, he could just soft link java21 to it.

That's basically what my suggestion does. I'm not saying to change the compiler. The command I gave him gives the option to set the default "java" command to be the 21 version. Note the difference between "javac" and "java".

Is there a better way to avoid doing this, ie removing java 17 and forcing 21 ? or vice versa to avoid this. I had not encountered this before in previous versions of Fedora it just worked! Now I have to specify. What would be the best thing to do? and make it work correctly.
I'd expect that within any sensible system, the java compiler and the java virtual machine would be compatible. The package java-17... seems to be an outlier and seems to be where the java virtual machine is coming from. If another package has a headless virtual machine, you might want to get rid of java-17... .
