Writing a File Interface

Question

I am writing this program to read in a file and filter it, so i can get some certain data into the database out of that interface. The program i wrote below keeps giving me the following error:
Exception in thread "main" java.util.NoSuchElementException
at java.lang.Throwable.fillInStackTrace(Native Method)
at java.lang.Throwable.<init>(Throwable.java:82)
at java.lang.Exception.<init>(Exception.java:33)
at java.lang.RuntimeException.<init>(RuntimeException.java:37)
at java.util.NoSuchElementException.<init>(NoSuchElementException.java:35)
at java.util.StringTokenizer.nextToken(Compiled Code)
at file.main(Compiled Code)
here is my code:
import java.io.*;
import java.util.*;
import java.text.*;
import java.util.Date;
public class file {
public static void main(String[] args) throws IOException {
// Display today's date using a default fomat for the current locale
DateFormat defaultDate = DateFormat.getDateInstance();
System.out.println(defaultDate.format(new Date()));
// Display Current time using a short time format for the current locale
DateFormat shortTime = DateFormat.getTimeInstance(DateFormat.SHORT);
System.out.println(shortTime.format(new Date()));
// Display date and time using a long format for both
DateFormat longTimestamp = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
System.out.println(longTimestamp.format(new Date()));
// Declare Variables
StringBuffer desc;
// Keep looking through the file while it is still not end of file
try {           
// Opens the file and reads it
File theFile = new File("23133202.2");
BufferedReader in = new BufferedReader(new FileReader(theFile));
// Get Length of File, and see how big it is
long filelength = theFile.length();
Date lastModified = new java.util.Date(theFile.lastModified());
String str = new String("");
int i=0;
// Read the file line by line using a Token
while((str = in.readLine()) != null){
StringTokenizer st = new StringTokenizer(str,":");
int count = st.countTokens();
// tokener contains all the field variables
String tokener = new String("");
Vector vec = new Vector();
System.out.println();
while(st.hasMoreTokens()){
vec.addElement(st.nextToken());
tokener = st.nextToken();
System.out.println(tokener);
} // end while
String[] strArray = new String[vec.size()];
vec.copyInto(strArray);
for (i=0; i<strArray.length; i++){
System.out.println(strArray);
} // end the main while
} // end try
catch (EOFException e) {
// end catch...in.close();
can anyone help me here please?

Answer 1

Do this instead:
// tokener contains all the field variables
String tokener = new String("");
Vector vec = new Vector();
System.out.println();
int count = st.countTokens();
for(int loop = 0; loop < count; loop++)
tokener = st.nextToken();
vec.addElement(tokener);
System.out.println(tokener);
This assumes that you want tokener to be the same token you put into the vector. If not, then you will need to make sure that the number of tokens in the tokenizer is even (so that you are able to get two tokens every loop) and increment loop by 2 instead of one every iteration.
