java - Querying the data once and using it throughout the app like a cache -

i have web app(simple jsp,servlets) oracle database. have scenario need

to consult dataset (~100 rows , 4 columns) of info mathematical calculation. so,

instead of putting in database every time , reading each row every time,

thinking of querying info once, , using throughout app cache. ideas

how best implement this?

you have around 400 values.are doubles? have 1600 bytes. why not read

then array?

java jsp servlets
