box api - Upload files to my personal box account using box api java sdk -

i create java application automatically uploads files personal box account using box api java sdk. can save credentials , not want enter them each time. not uploading files on other users' behalf , hence prefer not use oauth. can tell me how this?

you have authenticate using oauth2 since of box api calls require oauth2 token in header.

it looks java sdk auto-refresh token when it's expire, need authenticate once (unless application restarts).
