Hm,... maybe.
I think, which could be useful also for java methods.
I do not say I can't do without it.

According to https://www.mathworks.com/help/matlab/ref/which.html, only methods that are in classes that are "loaded" are returned.

This also implies the following syntax that Matlab supports, but Octave does not:


x = javaObject ("java.lang.String");
toString (x)


where the method is called as a function with the object as argument. I'm not saying this can't be done without that support, but that's what "which" seems to be paired with, the list of functions that you can call as a bare function.

according to 'Undocumented Secrets of MATLAB-Java Programming'
function which is also applicable to java methods.

which setSize
yields
setSize is a Java method  % javax.swing.JPanel method

which setSize -all
yields a list accordingly.
