8. puzzled in args.length coderanch.comWelcome to JavaRanch. That is a check whether there were any parameters passed in from the command line. Those would be in the "args" array, and "length" returns the number of elements in an array.

9. File length coderanch.comDepends on what you see as "counting". Does it go through the entire file and count bytes that way? No. Does it ask the file system what the file size is? Yes.

However, the result was never false, and checking the directory, once the declaration of the File object had executed, there was a file there (whose size was 0 bytes). You also misunderstood what I meant ... |
