Help with arrays

[Skorge]

Hello,
I'm a bit confused on how to do this. I'm supposed to open a dictionary file and store all of its values into an array. My guide tells me that I need to:

"read in the name of the dictionary file from command-line-arguments, then read in a dictionary of words from the data file, store each word in an array....."

I'm not exactly sure how to read the dictionary file from the command line arguments. Any help? :confused:

You don't. You read in the file name from the command line, then use that name to open a file for reading (myself I'd use a Scanner object for this. something like:

//pseudocode
main method 
  if the length of the args array is > 0 give args[0] to String fileName 
  Create a File object using fiileName
  Use this File to create a Scanner object
  initialize a counter int to 0
  while scanner's nextLine exists
    dictionary array [counter] gets assigned scanner's nextLine
    increment counter 
  end while
end main
