I have coded a applet program named Friends.java, long years ago (may be 5 years) and i made it out without any exceptions and i save the file in a CD. But now when i execute the program i don't get any Exceptions but when i execute appletviewer command i'm getting error message as:- "I/O Exception while reading: F:\Friends.html (The system cannot find the specified file)...
