[Octave-bug-tracker] [bug #46200] octave automatically converts java strings into char arrays

[Rik]

Follow-up Comment #1, bug #46200 (project octave):

Need someone with Matlab and some tests cases.  I think there may be a
distinction between returning the generic javaObject class, which then gets
queried by Matlab and converted if necessary, and returning a specific object
from a given class.

Otherwise, you it would be next to impossible to actually create a
java.lang.String object because it would always be auto-converted.

As an example, what does Matlab do for


jstr = javaObject ('java.lang.String', 'Hello World')
isjava (jstr)


My guess is that this remains an object, not converted to char.

On the other hand, the following code does do auto-conversion.  Presumably,
because a Java array is an array of the generic java.lang.Object type


octave:17> jarr = javaArray ('java.lang.String', 2,2)
jarr =

<Java object: java.lang.String[][]>

octave:18> jarr(1,2) = 'hello world'
jarr =

<Java object: java.lang.String[][]>

octave:19> % Now index into array
octave:19> jarr(1,2)
ans = hello world
