I take it this is some sort of programming exercise. It should probably read "Your output should be other than from a console-based Java program", meaning that output generated by a Java program running in a console is not acceptable. But if it's important, I would ask for clarification, because the sentence isn't correct and perhaps something else was meant.

The grammar is wrong. Check the sentence again to make sure you copied it correctly. Otherwise, ask the writer to correct him- or herself. Perhaps "should be another console....."?

Is that the whole sentence? other = either? You output should either be a console based Java program (or a GUI application).
