By using FileReader, FileWriter and their constituents, I am creating a file to contain employee information ( name, age, hours, etc. ). The user is to input all of the data on a single line and we were asked to implement StringTokenizer to assign that data to the file. I have never used the StringTokenizer before, but I have a rough idea how it is to function. I used pw.println to test what I have so far, now I would like to let the user build the initial file with the "first employees" of the company, and then view the file, and then go back and append new employee data to that same file. My question is, how can I take the user input as a StringTokenizer and add that to the file?
In the for loop below, I thought I would see if it would work, but it does not. The loop only executes once and does not allow me to enter data.
public class Records {
public static void main(String [] args) throws IOException {
Scanner input = new Scanner(System.in);
FileWriter fw = new FileWriter("dbs3.java");
BufferedWriter bw = new BufferedWriter(fw);
PrintWriter pw = new PrintWriter(bw);
System.out.println("NEW EMPLOYEE DATA SHEET");
System.out.print("Number of new employees: ");
int number = input.nextInt();

Conditions : Need to print all the inputted data(name,score) and the average.

I have created a gui which accepts username in the text field and once clicking on submit button it fetches user details and throws it on gui via JTable.
But when i click submit for the second time using different username the background process goes well and good the vector that i pass to jtable changes with new data but the values in gui still contain the old data.
I am relatively new to JSF. I am trying to display data into a web page sorta like a jTextArea or at least onto a panel that is on the webpage, something similar to that. I can display the data in a particular format but it won't appear onto a panel in a specific location or the panel being a particular size.

I have 3 csv files as follows -
author file columns - emailID | firstname | lastname
books file columns - title | isbn | author_email | description
magazine file Columns - title | isbn | author_email | releasedate

1) Based on the ISBN display all books and magazines
2) All books and magazines by an author
3) All books and magazines by title
I am using Buffered reader as of now -
String csvFileToRead = "csvFiles/authors.csv";
BufferedReader br = null;
String line = "";
String splitBy = ";";
[Code] ....
I am confused about how to proceed with multiple files. Here are the approaches that i have considered -
1) change string csv csvFileToRead to a string array -
String[] csvFileToRead = {"data/autoren.csv", "data/buecher.csv", "data/zeitschriften.csv"};
Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?
2) Should i make 3 different classes with getters and setters for authors, book and magazine?
I written java code in JSP to display data. I know it is bad practice. Actually my Business-service communicates with DB and returning data in the form of MAP. I don't have beans Because the fields in DB is dynamically changing. So, for now I'm retrieving Data by writing Java code in JSP. Is there any other way to display data without writing java code in JSP?

View Replies View RelatedI have a tree-based data structure that looks somewhat like this:image1.png..Every tree always has a height of no more then 3, and each of these classes has a very specific use, generalization is not possible between them.Now, I want to display my data structure with a JTree in a Swing application. A JTree needs a TreeModel and so I created a custom TreeModel for my classes, it looks like this:
public class CustomTreeModel implements TreeModel {
private Root root;
public Object getRoot() {
return root;
[code]....
But then I would introduce this interface to my Model classes just for the purpose of writing the View. So my data model has to be altered to make the View work, this sounds completely against MVC to me and also like something I dont really like.On the other hand, the CustomTreeModel would be much simpler, easier to understand, easier to maintain and just in general more pleasing to the eye.Should I change my Model to improve the View? Is instanceof okay to be used in View classes?
My problem is to read a text file which contains lines of text data
{e.g: #1115=CLOSED_SHELL(",(#166,#208,#250.....#1114));}
I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}
like this 8 levels were there, finally at each level the Calling number should display in JTable.
