But this is in Java so it *must* be in some sort of class.  This
signature doesn't include "static" so you need to have an instance of
the class to invoke the method on.

| from jarray import array

This line isn't needed.  You only need to use the jarray module if you
want to create a new array from jython code.

| arr = read() # I am not able to do this

This line tries to find an object named "read" first in the local scope of the
function it is in then in the scope of the module it is in, then
checks the builtins.  There is no such object so the lookup fails.  As
noted above, you need to create an instance of the java class so that
you can invoke the method on it.
