FileNotFoundException

[ProgrammingPup]

The string i input as the filename looks like this:

"http://avery.agron.iastate.edu/JavaBrowser/data/B2.txt"

the console gives me back an error saying:

File not found!
java.io.FileNotFoundException: http:\avery.agron.iastate.edu\JavaBrowser\data\B2. txt (The filename, directory name, or volume label syntax is incorrect)

Why do the slashes change when the console gives me the error? I am so confused......

Just before line 100 of HaploTable.java use System.out.println() to output the value you are using as the file name. If it is not what you expect you have to use a debugger - or more println() statements - to find where you are changing the value from that which was input.

In fact on Windows a filename like that is going to cause grief whichever way round the slashes go.

A SSCCE would be very useful. But note the first "S"! Hundreds of lines of code will only obscure the problem.

Oh, it's an applet! (I've just read your other thread - and yes people dislike multiposting much more than they dislike a possibly misplaced post)

Applets probably won't use files at all. So there is something very wrong with your use of Scanner.

Hey i figured it out!! a while ago!! sorry if this was not in the right place. at the time i did not know it was a problem due to the applet.

Yes the problem was with using File to read in the the file. Instead i had to use URL and InputStream. I finally got my applet to work!!!!!

everyone celebrate my first working applet!!! (well if u dont count a HelloWorld Applet hahah)

Well done!
