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

Looks like the compiler you're running is newer than the runtime you're using.
What do "javac --version" and "java --version" show? What does "rpm -qa | grep openjdk" show? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
