Newbie JCreator NoSuchElementException Help!
I'm trying to run a project that involves using no global variables other than the import ones seen below. It's supposed to read a text file with three lines of words. (I've attached it) and then scan them and add a certain suffix or turn the words plural depending on their endings. I have the project running but it seems that it won't read the next line in the input file, and gives me this error.
--------------------------------------------------------------------------
XQAC ZVM
Original String: XQAC ZVM
Plural: XQACCH
Suffix: XQCZVM
Exception in thread "main" java.util.NoSuchElementException
at java.util.StringTokenizer.nextToken(StringTokenize r.java:332)
at VowelsRUsNoGlobals2.main(VowelsRUsNoGlobals2.java: 47)
Process completed.
--------------------------------------------------------------------------
The output should look like that first bit of the out put but with three different lines. I tried following the NoSuchElementException, but I am new and still having trouble. Here is the code, any and all help is greatly appreciated!

Re: Newbie JCreator NoSuchElementException Help!
I believe I have a solution to your problem. Instead of using the import statement you did for the infile, try doing this:
Add these three import statements:
import java.util.*;
import java.io.*;
import java.lang.*;
Use this for importing your file
Scanner infile = new Scanner(new File ("Vowels.txt"));
from there use statements such as
int x = infile.nextInt();
String s = infile.nextLine();
and others to call your text file. It leaves much less room for error.

It is never necessary to import any class from the java.lang package, as they are automatically imported.
