I am getting a duplicate local variable at the line
" Scanner file = new Scanner( new File("c:/eclipse/numbers"));"
I am a noob to this, and honestly cannot figure it out. Any advice/input would be great.
You defined File file
earlier, so that name is taken when you define Scanner file
. Change one of them and everywhere you reference it.
Note that a try
block doesn't have its own local variables; it shares those of the parent section.
