[Jython-users] In Jython, how to write a Java Array/Arraylist to a file?

[pompeez <kaj...@gm...>]

Hi,
I need to write a Java Array/ArrayList/List to a text file in Jython. I used
the .write() function, but it is letting me write only a string.
Thanks!

Try .writelines() instead.
I've found this to be very helpful maybe you will too. Its a python
quick ref. http://rgruet.free.fr/PQR25/PQR2.5.html=20

Make sure the elements contained in the ArrayList implement
java.io.Serializable and then:
from java.io import File, ObjectOutputStream, FileOutputStream
# ArrayList a = ArrayList()
# a.add(1)
# ...
f=File.createTempFile("prefix", ".ext")
fos=FileOutputStream(f)
oos=ObjectOutputStream(fos)
oos.writeObject(a)
oos.flush()
oos.close()
fos.close()
f.deleteOnExit(0)
print f.name+'\n'
Hope that's sorted.

ObjectOutputStream doesn't write text, it writes binary.
