Hi Andrew:

Thanks very much for your efforts on both the Java examples and bindings.

I do have plans to change bindings/swig-support/plplotcapi.i and
bindings/java/plplotjavac.i to deal with translating PLBOOL directly to Java
boolean so I think the net effect will be that, for example, both the
swig-generated interfaces plplotjavac.plcpstrm and plplotjavacJNI.plcpstrm
will have a boolean argument. I notice the syntax you use to translate a
boolean to integer is flags?1:0 where flags is a boolean.  What java syntax
do you recommend to translate an integer to boolean in PLStream.java?  I
will need that for the deprecated bindings (and also I will have to replace
your "flags?1:0" form by "flags" in the recommended bindings) once the
bindings/swig-support/plplotcapi.i and bindings/java/plplotjavac.i are in
place.  However, that editing change should be trivial now that you have
identified how to do the overloading and done the editing work to implement
it in PLStream.java for the current bindings/swig-support/plplotcapi.i and
bindings/java/plplotjavac.i.
