[Octave-bug-tracker] [bug #60058] Feature request: function javaversion()

[Ernst Reissner]

Follow-up Comment #11, bug #60058 (project octave):

I agree as long as they just pass. 
But I wonder whether octave assembles the version string itself. 

look: 
java --version yields 
openjdk 11.0.10 2021-01-19
OpenJDK Runtime Environment (build 11.0.10+9-suse-1.1-x8664)
OpenJDK 64-Bit Server VM (build 11.0.10+9-suse-1.1-x8664, mixed mode)

whereas 
octave:1> version('-java')
ans = Java 11.0.10+9-suse-1.1-x8664 with Oracle Corporation OpenJDK 64-Bit
Server VM mixed mode

So, octave does something. 
Else, maybe: 'version('-java') returns version as returned by... 
I dont know. 
Note that also vendor information is returned. 

Anyway, i removed my own version method, although more precise, 
to use the generic one with the regular expression 
you suggested.
