Maybe a newbie question, if you use google then also you could have got the answer. Try creating a jar file of your java program and run it through a shell script by passing arguments from a file like,

get values from file using shell command amd grep,cut,awk etc.

val=`grep "expcted filter" file`
va2=`grep "expcted filter" file`

java -jar <your jar file>  $val1 $val2 > outputfile.txt

This will redirect output to a file which you can print through shell
