How can visualize a grib data on my map in Java?

Hi to everyone, i'm developing an app android based on openstreetmap, and now i need to implement a class that visualize a grib data on tiles. I already read a grib file, i saved it ASII GRID format and i can visualize with external software correctly. Are there some example in java that i can use for it? Thak you in advance.
