Seeds and cultivated grains, especially rice, gathered from the ground and grass stems.
Do not deliberately feed Java Sparrows; secure grain and spilled birdseed to avoid creating large introduced-species flocks.

Uses cavities and can nest communally; do not provide nesting structures to encourage local introduced populations.
