NoSuchElementException... help!!

[mpthegeneral]

Hello,
I'm new to java and I'm attempting to write a simple database using static arrays.
The problem that i cannot get past is in a method that reads a text file into the array.

Below is the .txt file that the method is reading from.
(note: "|" is used as the delimeter and there are not supposed to be lines between each entry in the .txt file.)

Bob|Marley|1993@yahoo.com|Monday, Tuesday, Thursday before and after school|Intermediate|CompSci 

John|Doe|jd@yahoo.com|Monday, Thursday after school|Novice|CompSci 

Billy|Mays|bm@yahoo.com|Monday, Tuesday before school|Expert|CompSci 

Fred|Flintstone|fff@yahoo.com|Monday, Tuesday, Thursday before and after school|Newbie|CompSci

And this is the file reading method:

public void read(File f)
    {
    	//clear array
    	members = new TeamMember[100];
    	count = 0;
   	
    	Scanner input = null;
		try 
		{
			input = new Scanner(f);
			input = input.useDelimiter("|");
			
			while(input.hasNext())
			{
				String first = input.next();
				String last = input.next();
				String email = input.next();
				String avail = input.next();
				String skill = input.next();
				String exp = input.next();
				
				if(input.hasNext())
				{
					input.nextLine();
				}
			
				TeamMember temp = new TeamMember(first, last, email, avail, skill, exp);
				addMember(temp);
				
				count++;
			}
			
			input.close();
			
		} 
		catch (FileNotFoundException e) 
		{
			System.out.println("/n	ERROR: " + e.getMessage());
		}
    }

I have not the slightest clue on how to fix this issue. I've been searching around on Google for the past 3 hours.
Please help me solve this issue, this is due soon.. :(
Any and all help is greatly appreciated! :D

What is the exact runtime error message? And what line of your code does it refer to?

----------------

You can get more information about exactly where the problem occurs (both in terms of your code and in terms of the data file) by adding some diagnostic output.

while(input.hasNext())
{
    String first = input.next();
    String last = input.next();
    String email = input.next();
    String avail = input.next();
    String skill = input.next();
    String exp = input.next();
    
    [color=blue]System.out.printf("Read %s %s %s %s %s %s%n", first, last, email, avail, skill, exp);[/color]
				
    if(input.hasNext())
    {
        input.nextLine();
    }
			
    TeamMember temp = new TeamMember(first, last, email, avail, skill, exp);
    addMember(temp);
				
    count++;
}

Oh, I'm sorry I forgot that. Here it is:

Exception in thread "main" java.util.NoSuchElementException
	at java.util.Scanner.throwFor(Unknown Source)
	at java.util.Scanner.next(Unknown Source)
	at TeamDatabase.read(TeamDatabase.java:79)
	at CSTeam.dispatch(CSTeam.java:142)
	at CSTeam.main(CSTeam.java:53)

And its is referring to line 79 which is

String email = input.next();

in the read method.

EDIT: Also I did the diagnostic output you suggested and received the following:

Read Bob | Ma
Read 
 
 J o h n
Read 
 
 B i l l
Read 
 
 F r e d

What does it mean?

[Fubarable]

Myself, I would use a standard Scanner with the default delimiter to get each line in the file via:

while (input.hasNextLine) {
  String line = input.nextLine();
  //...
}

and then would split each line using String#split(...) using "\\|" as the regex for splitting. I would use \\ to escape the | character since | has special meaning in regex.

If you must use Scanner, then I'd use two Scanners, one to read in each line that uses the default delimiter (similar to above) and a second that works on each line obtained. I would still escape the | character the same: "\\|" for my Scanner delimiter.

Thank you but I am fairly new to this and I don't understand much of what you said. This program pretty much entails all of my current knowledge of Java; however, I did escape the delimeter and the new diagnostic output became this:

Read Bob Marley bm@yahoo.com Monday, Tuesday, Thursday before and after school Intermediate CompSci 
 
Read John Doe jd@yahoo.com Monday, Thursday after school Novice CompSci 
 
Read Billy Mays bm@yahoo.com Monday, Tuesday before school Expert CompSci 
 
Read Fred Flintstone fff@yahoo.com Monday, Tuesday, Thursday before and after school Newbie CompSci

Does this mean it worked?
*Sorry for all the edits..

[pbrockway2]

Does this mean it worked?

Hard to say without knowing the code... (did you stick with one scanner and escape the | when you set the delimiter?)

Anyway, where in the world is John Doe? Somehow or other "<newline>John" got included as part of the Bob Marley data. And then the rest of John Doe's data was lost.

I agree with foobarable. You are doing two things with the text in the file: splitting on newlines, then splitting on the pipe. To elaborate on his code:

import java.io.StringReader;
import java.util.Scanner;

public class RecordReader {

    public static void main(String[] args) {
            // we can imitate reading from a file
        String data = "red|3|stop\ngreen|5|go\nblue|4|no value";
        Scanner input = new Scanner(new StringReader(data));
		
        while(input.hasNextLine()) {
            String line = input.nextLine();
            String[] fields = line.split("\\|");
			
            System.out.printf("Data read: %s %s %s%n", fields[0], fields[1], fields[2]);
            // now do whatever you like with the fields
        }
    }
}

... (did you stick with one scanner and escape the | when you set the delimiter?)

Yes I did and it worked.

Anyway, where in the world is John Doe?

That was just an issue with my .txt file which I have fixed.

I still don't understand much of the code you posted but thank you. I think my problem is now resolved! :D

Much thanks Fubarable and pbrockway2!! :)
