If you are using eclipse you can pass the arguments by right clicking the project

RUN + Arguments tab and enter arguments giving a space

eX: num1 num2 ( Can be input/output files as well if you are parsing with excel or txt etc)

I haven't read all the posts but this is the answer if this is what you are looking for
