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

[olivares@fedora mptmp]$ javac Area_Triangle_Determinants.java
[olivares@fedora mptmp]$ java Area_Triangle_Determinants
Error: LinkageError occurred while loading main class Area_Triangle_Determinants
java.lang.UnsupportedClassVersionError: Area_Triangle_Determinants has been compiled by a
more recent version of the Java Runtime (class file version 65.0), this version of the
Java Runtime only recognizes class file versions up to 61.0
[olivares@fedora mptmp]$
I had another program called Ulam (3n+1) conjecture, Or Collatz Conjecture and it also
fails to run.
[olivares@fedora mptmp]$ javac Ulam.java
[olivares@fedora mptmp]$ java Ulam
Error: LinkageError occurred while loading main class Ulam

[olivares@fedora mptmp]$
I have not been able to run theses programs using openjdk ...

[olivares@fedora mptmp]$
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.
