It probably will be file input/output. The grader was made this way because it seems to be the standard of high school contests. Also, you'll need to use file IO eventually anyways.
Some examples of java file IO can be found at http://access.mmhs.ca/ccc/index.htm. It has code of the past CCC stage 1 problems written in java and most of the ones use file IO. I've looked at some of the code and the file IO doesn't seem to be that bad.
