I'd assume that java sparrows would be very similar to handfeeding a regular finch, so you should just search for that topic. It may depend on the parents as to whether they'd abandon the nest or not. If you were going to handfeed them, I wouldn't pull them to feed, then put them back into the nest.
I personally don't believe in pulling birds that small for handfeeding. If I remember right, people friendly java sparrows are big in Japan. At least that's where I've always read about them. My opinion would be to let the parents raise them, and attempt to tame the young after they leave the nest, if that's something you really wanna do.
