    Question Problem reading in the files

    I have this piece of code that is suppose to read in a file and count how many lines it has, number of words, etc... but for some reason it is not reading this file in for some reason

    http://faculty.utpa.edu/rtschweller/...dictionary.txt

    I can put in other inputs and other words, as a matter of fact, I can put what I want and it will read the file properly and do everything i ask it to. I can even give it huge files that take my computer a while to compute and it will still work but once I give it this file, it will not read it at all. I can erase all of it's input and put something else in this file it will read it but I give it the input in the file it won't read it. I even cut this file in half a few times until i gave it a tiny input and it started reading it. I copied it over millions of times and it read it, I give it back this file's input again, it won't even attempt to read it.

    Any suggestions?

    it is not reading this file in for some reason
    Are there any error messages when the program is executed? Copy the full text and paste it here. Add a call to the printStackTrace() method to the catch block to show the full text of the error message.

    If the file you are having problems with is a text file, copy its contents and paste it here.

    It compiles just fine and all but it won't read it in. It won't even throw the exception

    What does the code do when it is executed? Add an if statement inside the while loop to print out a message every 100 lines it reads. Something line this:
      if(lineCount % 100 == 0) System.out.println("lC="+lineCount);
    That will show you what the code in the loop is doing.

    It will read files in like it is supposed to. It is suppose to count the lines and words in the document but it doesn't matter what I give it, it works. I would of put the statement you put in cause I do like your tips alot norm but I ran through it step by step and for other entries, even if it is the same file, regardless if they are bigger or smaller or what not, will read in and count like it is suppose to but when I put in this dictionary that I linked in the orginal comment, it won't even try the loop, it just goes, immediately returns false and skips over the loop completely.

    I have no idea what is wrong with the working of the program on your system.

    Well, at least you tried. I ask my professor the same thing and it just baffles him as much as it does you. I take it you never seen something quite like this? I swear it's crazy and people think I'm making it up but I'm like trust me, it's too stupid for me to make up

    What happens if you read the file in an editor and save it with a different name?
    When I use the program with the file:

    The report:
    Number of lines: 202412
    Number of words: 202412
    Number of chars: 1852943
    This is ok for work

    It opens up normally in any editor and I just tried a different name. Nothing. I tried this on another computer, still the same thing. I'm using netbeans if that helps. I also used different editors and nothing. I still get 0 for everything. I even restarted the system and still nothing

    I'm using Eclipse and it works fine.

    Where did you put the file and what did you call it?

    Try creating a small data file with a few lines and see if that works.

    I'm using netbeans like I said but I could try using eclipse, would that work? I have in the "My Documents" folder my netbeans folder where it then saves all my projects by default in the projects folder. My project "Dictionary" as I simply called it, is listed and when I open it, in the first page you see is where I dropped the file. It appears to read it in and its only with this text, which I need mind you, not trying to be rude, that it decides, nope, I'm not even going to try to read the file. I already tried to modify the file in different ways to see if there is a reason why it isn't doing anything. Different mods and editors don't do anything. I thought it was too big to read so I gave it another file and increased it's size and it read it just fine. I gave it a 100MB file to read in of useless text and it did read it. I even put in frack and it detected it in the text. SO I know it read all 4 millions lines of text. I don't change a thing other than I simply give it this dictionary, nothing. I tried changing the name, nothing

    I don't think using an IDE helps. Try opening a command prompt window and using the java command to execute the program.

    Your use of IDEs has isolated you from how things work.
    See the tutorial:
