Need Help in JTable setValueAt method()

hi to all i am new to this forum. i am trying to create user creation using JTable
Here my code
import javax.swing.table.*;
import java.awt.*;
import java.util.*;

public class user_table1 extends JDialog implements ActionListener,TableModelListener{
JTable tab;
JButton print_but,add_but,rem_but;
DefaultTableModel md;
    public user_table1() {
        super();
        setLayout(null);
        setTitle("Table Demo...");
         md=new javax.swing.table.DefaultTableModel(
            new Object [][] {
                {"Dinesh", new Boolean(false),new Boolean(false)},
                {"Kumar", new Boolean(false),new Boolean(false)},
            new String [] {
                "user name", "Admin","User Enabled"
            Class[] types = new Class [] {

            public Class getColumnClass(int columnIndex) {
                return types [columnIndex];
        tab=new JTable(md);
        JScrollPane js=new JScrollPane(tab);
        js.setBounds(0,0,500,300);
        print_but=new JButton("Print Data");

     public void actionPerformed(ActionEvent e) {

         int nu=tab.getRowCount();

                   System.out.print (tab.getModel().getValueAt(i,j)+"\t\t");
              System.out.println ();
       if(e.getSource().equals(add_but))
        int rowval=tab.getRowCount();
      md.addRow(new Object [][] {{"New User", null}});
        md.setValueAt("New User "+tab.getRowCount()+"",tab.getRowCount()-1,0);
       if(e.getSource().equals(rem_but))
                if(tab.getSelectedRow()<0)
                 JOptionPane.showMessageDialog(this,"Select User To Remove");
                else
                       md.removeRow(tab.getSelectedRow());
        public void tableChanged(TableModelEvent e) {
        if(e.getType()==TableModelEvent.UPDATE)
                System.out.println("Update Row "+tab.getSelectedRow()+"Col :"+tab.getSelectedColumn());
                //System.out.println("New Values.."+md.getValueAt(tab.getSelectedRow(),tab.getSelectedColumn()));
                if(tab.getSelectedColumn()==1)
                        if(md.getValueAt(tab.getSelectedRow(),tab.getSelectedColumn()).toString().equals("true"))
                                        md.setValueAt(new Boolean(true),tab.getSelectedRow(),2);
    public static void main(String sr[])
    java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                user_table1 dialog = new user_table1();
                dialog.addWindowListener(new java.awt.event.WindowAdapter() {
                    public void windowClosing(java.awt.event.WindowEvent e) {
                        System.exit(0);
                dialog.setVisible(true);
}i need If the user Set as admin then automatically corresponding user Enabled row is set as true
so i write the following code in
md.setValueAt(new Boolean(true),tab.getSelectedRow(),2);
It triggers tableupdate event again and again and prints
Update Row 0Col :1
Update Row 0Col :1
Update Row 0Col :1
Update Row 0Col :1
Update Row 0Col :1
Update Row 0Col :1
more then 200 times
and give the exception as
Exception in thread "AWT-EventQueue-0" java.lang.StackOverflowError

please give solution or example for this problem and some idea to disable UserEnabled column row when corresponding Admin Column row value is true.

if(e.getType()==TableModelEvent.UPDATE)
                System.out.println("Update Row "+tab.getSelectedRow()+"Col :"+tab.getSelectedColumn());
                //System.out.println("New Values.."+md.getValueAt(tab.getSelectedRow(),tab.getSelectedColumn()));
                if(tab.getSelectedColumn()==1)
                        if(md.getValueAt(tab.getSelectedRow(),tab.getSelectedColumn()).toString().equals("true"))
                                        md.setValueAt(new Boolean(true),tab.getSelectedRow(),2);
        }You created an infinite loop. When the selected column is 1, you update a value in column 2, which generates another TableModelEvent. The selected column is still 1, so the column is updated again, which fires another TableModelEvent.
You should not be checking the selected column. You should be using the row and column from the TableModelEvent to determine which cell was just updated.

Need Help with a getText method

Gday all,
I need help with a getText method, i need to extract text from a JTextField. Although this text then needs to converted to a double so that i can multiply a number that i have already specified. As you may of guessed that the text i need to extract already will be in a double format.e.g 0.1 or 0.0000004 etc
Thanks for your help
ps heres what i have already done its not very good though
ToBeConverted.getText();
( need help here)
double amount = (and here)
total = (amount*.621371192);
Converted.setText("= " + total);

Double.parseDouble( textField.getText() );

I need help with my remove method on a BST!

Guys I need some help here, I have to create a remove method for a BST and below is my code:
public boolean remove(OrderedMap map, K keyOfelementToRemove) {
          boolean result = false;
          if (root == null)
               result = false;
          else {
               MapNode curr = root;
               MapNode prev = root;
               while (curr.key.equals(keyOfelementToRemove) == false) {
                    prev = curr;
                    if (keyOfelementToRemove.compareTo(curr.key) < 0)
                         curr = curr.left;
                    else if (keyOfelementToRemove.compareTo(curr.key) > 0)
                         curr = curr.right;
                    if (curr == null)
                         break;
               if (curr == null)
                    return result;
               else if (curr == root && curr.left == null)
                    root = root.right;
               else if (curr.left == null) {
                    if (curr.right == null)
                         curr = null;
                    else if (curr == prev.left)
                         prev = curr.right;
                    else if (curr == prev.right){
                         prev = curr.right;
               else if (curr.left != null) {
                    MapNode temp = curr.left;
                    while (temp.right != null)
                         temp = temp.right;
                    K change = temp.key;
                    temp = null;
                    curr.key = change;
          size--;
          return result;
     }the algorithm that my instructor provides is:
private boolean remove( BinaryTreeNode t, Comparable elementToRemove )
Set result to false
Traverse the tree t until elementToRemove is found. Use curr and prev to find the element
leaving curr referring the node you want to remove. It may be the case that curr is null indicating
that elementToRemove was not found. Now there are four cases to consider :
Case 1: Not found
return result (false)
Case 2: The root is to be removed, but it has no left child.
root = root's right subtree (assuming root refers the the root node in your BST)
Case 3: The node is further down tree with no left child. Now must adjust one of the parent's links
if curr is on the left side of prev,
move parent's left link down to down to curr's right child
else
curr is on the right side of prev, so move parent's right down to down to curr's right child
Case 4: curr has a left child.
We can no longer ignore the left subtree. So find the maximum in the left subtree and
move that object to the node referenced by curr . Then eliminate the maximum in the
left subtree, which is now being reference from the original node to remove.
however for case 3 and 4 it doesn't work, can someone please tell me why? I don't know where I made a mistake and I tried finding it but I still dont know

I am sorry about the double post. I'll try not to do this again. My problem here seems to be that prev and curr aren't updating the BST outside this method, which means that it only changes locally but not permanently. I will post the code of the other headings:
public class OrderedMap<K extends Comparable<K>, V> {
     private class MapNode {
          // Links to other BSTs
          private MapNode left;
          private MapNode right;
          ArrayList<V> temp1 = new ArrayList<V>();
          // The references to the key/value pair of the mapping
          private K key;
          @SuppressWarnings("unused")
          private V value;
          public MapNode(K theKey, V theValue) {
               key = theKey;
               value = theValue;
               left = null;
               right = null;
     } // end class MapNode
     private MapNode root;
     private int size;
     public OrderedMap() { // Create an empty tree
          root = null;
          size = 0;
     public int size() {
          return size;
     }

Need Help with new Classes / methods

Hi, I need to create a class called Proposition. It include a Proposition object with 3 variables
Name, Description, Value
This is the constructor I wrote:
private String name;
private String description;
private boolean value;
public Proposition(){
          name = "name";
          description = "description";
          value = false;
}Now I need a method that give values to the 3 variables in the proposition object:
     public Proposition setProp(String line){
          StringTokenizer ST1 = new StringTokenizer(line, ".");
          String ValidLine = ST1.nextToken()+".";
          StringTokenizer ST2 = new StringTokenizer(ValidLine, "=");
          name = CutSpace(ST2.nextToken());
          description = (ST2.nextToken()).trim();
          value = false;
          return name;
          return description;
          return value;
     }An example of String line is: v = we are in Vancouver.
When I run the program, I got error message with the 3 return statements saying found String/Boolean while Proposition is needed. I'm not quite sure how to write the return statements. Can any1 help?
Thx!

Your setProp() method should not be returning anything. After all it is setting not getting. So just declare it as
public void setProp(String line){and remove the return statements.

Need help getting DataProvider cursor methods to work in JSC

Hi, I'm a newbie to Creator as well as JSF. I'm using JSC Update 1. I've
worked through a couple of the beginning tutorials including "Performing
Inserts, Updates, and Deletes" without a problem. I'm now trying to
craft a simple jsf database form application on my own using the sample
travel database and I'm stuck!
I put text fields on the form corresponding to each of the 4 fields in
the PERSON table and bound them to the fields in the table which, on
examination, resulted in a CachedRowSetDataProvider (personDataProvider)
in Page1 and a CachedRowSetXImpl (personRowSet) in SessionBean1. I then put 4 buttons on the form (First, Previous, Next, Last) for record
navigation. Here is the code I put in the first two actions (the others are
the same except for the cursor methods):
public String btn_firstrec_action() {
try {
personDataProvider.cursorFirst();
} catch (Exception e){
error("cursorFirst failed: " + e.getMessage());
log("cursorFirst failed " , e);
return null;
public String btn_next_action() {
try {
personDataProvider.cursorNext();
} catch (Exception e){
error("cursorNext failed: "+ e.getMessage() );
log("cursorNext failed " , e);
return null;
etc.
When I run the application using the bundled app server I get strange
behavior when I click the navigation buttons. There are 6 records in the
table. The application opens up displaying the data for the first
record. Clicking "Next" takes me to record 2--so far so good. However,
with repeated clicks on "Next", "Previous", "First" the data displayed in
the form remains the same. If I click "Last" (personDataProvider.cursorLast(); ), the data from record 6 is rendered OK!
I worked a little in the debugger. I added a cursorChanging method and
put a break point in there. Then I watched the index attributes for rk1
an rk2 as I continued the execution. I had to hit Alt+F5 (Continue)
2 to 4 times on each button click depending on the action--4X
with "Next" and "Previous". For each button click the index values would
change at first to what logically seemed the correct values but
then snap back to 0 or 1 as I kept continuing depending on the sequence--
wierd to me.
I also tried configuring all the form fields in a virtual form with
"Participate" on for the text fields and "Submit" on for the buttons
with the same result (I was really "shooting in the dark" here!).
I'm obviously missing something here--this shouldn't be this difficult!
I have scanned through a lot of the excellent tutorials, articles and forum posts as well as some of the sample apps but haven't as yet found a similar example of using the DataProvider cursor methods which seems pretty basic to me but, I could have easily missed seeing what I needed.
Any help would be greatly appreciated--I'm really counting on this tool
to get an overdue project going so I'm somewhat desperate.
Thanks, Len Sisson

This happened to me as well the first time I used the JSC (and I was a newbie in web). I believe it is because everytime you hit the button, actually the sequence of program will back to init(), button_action(), prerender(), destroy(). So, try to remember the last state of the cursor position using session variable. And then you put a code in the init() to move back to the last cursor position.
Check the sample program provided by JSC (SinglePageCrudForm). This sample demonstrate how to put a code in init(), destroy() in order to 'remember' the last position.
hope that helps

NEED HELP WITH USING STATIC METHOD - PLEASE RESPOND ASAP!

I am trying to set a value on a class using a static method. I have defined a servlet attribute (let's call it myAttribute) on my webserver. I have a serlvet (let's call it myServlet) that has an init() method. I have modified this init() method to retrieve the attribute value (myAttribute). I need to make this attribute value accessible in another class (let's call it myOtherClass), so my question revolves around not knowing how to set this attribute value on my other class using a static method (let's call it setMyStuff()). I want to be able to make a call to the static method setMyStuff() with the value of my servlet attribute. I dont know enough about static member variables and methods. I need to know what to do in my init() method. I need to know what else I need to do in myServlet and also what all I need in the other class as well. I feel like a lot of my problems revolve around not knowing the proper syntax as well.
Please reply soon!!! Thanks in advance.

Need help with a remove method..

Hello. I'm getting started on a project here to implement a recursive remove method that will remove any number from a list. I was given a test that the method must pass, but I'm having some trouble getting started. This is my second interaction with the idea of recursion and it's a bit difficult for me.
Here is the test I'm writing the method for:
public void testRemove() {
          int element=0;
          boolean inList = false;
          for (int i = -10; i < 11; i++)list.insert(i);
          int numElements = list.length();
          list.remove(element);
          for (int e : list) {
               if ( e == element ) inList = true;
          assertTrue(!inList && (list.length()==(numElements-1)));
          element = -10;
          inList = false;
          list.remove(element);
          for (int e : list) {
               if ( e == element ) inList = true;
          assertTrue(!inList && (list.length()==(numElements-2)));
          element = 10;
          inList = false;
          list.remove(element);
          for (int e : list) {
               if ( e == element ) inList = true;
          assertTrue(!inList && (list.length()==(numElements-3)));
          //does remove work when element's value greater than value of last item in list
          element = 20;
          inList = false;
          list.remove(element);
          for (int e : list) {
               if ( e == element ) inList = true;
          assertTrue(!inList && (list.length()==(numElements-3)));
          //does remove work when element's value less than value of first item in list
          element = -20;
          inList = false;
          list.remove(element);
          for (int e : list) {
               if ( e == element ) inList = true;
          assertTrue(!inList && (list.length()==(numElements-3)));
          System.out.printf("%s\n", "testRemove " + list.toString());
     }Now, clearly I need to test whether or not the number being removed is in the list (too low/too high), but I'm stuck trying to implement this.
If anyone can give me any ideas or direction it would be greatly appreciated.

Thanks for the quick reply, from what I had gathered and what you posted I'm starting to see where I need to go from here. I had gotten as far as if list is null return null, and the cod that you posted makes sense, but implementing it into the source code I already have will be troubling for me. The code as you presented it I have no trouble understanding, for example:
if (list.data == data) return list.next;
list.next=remove(list.next, data);Is clear to me, however I don't know how to implement that into my code. This is the code for the insert method:
     private Node<ElementType> insertp(Node<ElementType> list, ElementType element) {
          if ( (list == null) || ( element.compareTo(list.getElement() ) < 0 ) ) {
               // test for insert at head or before current node
               Node<ElementType> newNode = new Node<ElementType>(element, null);
               newNode.setNext(list);
               return newNode;
          else if (list.getNext() == null) { // list with one element
               Node<ElementType> newNode = new Node<ElementType>(element, null);
               list.setNext(newNode);         // element goes at end
          else if ( element.compareTo(list.getNext().getElement()) < 0 ) { // insert after list
               Node<ElementType> newNode = new Node<ElementType>(element, list.getNext());
               //newNode.setNext(list.getNext());
               list.setNext(newNode);
          else {
               insertp(list.getNext(), element); // find insertion point
          return list;
     }I'm still struggling to understand all of the code there. the element.compareTo() and everything. If you (or some one else) can explain to me what is going on with those methods, I may be able to implement it myself. Also, this may be of some use, these are the methods I have available to me:
public class Node<E> {
// Instance variables:
private E element;
private Node<E> next;
/** Creates a node with null references to its element and next node. */
public Node() {
    this(null, null);
/** Creates a node with the given element and next node. */
public Node(E e, Node<E> n) {
    element = e;
    next = n;
// Accessor methods:
public E getElement() {
    return element;
public Node<E> getNext() {
    return next;
// Modifier methods:
public void setElement(E newElem) {
    element = newElem;
public void setNext(Node<E> newNext) {
    next = newNext;
public String toString() {
       return element.toString();
}

Need help with project (calling methods) please!!

Hi there i have a project for uni requiring me to create a java program that creates a random No. and lets the user have three guesses to find the No. When the users guesses correct he gets a message telling him hes won and if he doesnt get it correct he gets a message telling him the correct No then terminates.
The code has to call an outside method called[b] Public Static Boolean CheckGuess
I have tried to create this and got it to compile with no errors (eventually) but i keep getting a message saying i have whenever i type any number in. I think the problem is the way i am calling the method i havnt got much experience this is all pretty new to me any help would be really appreciated. Thanks.

Thank you very much that worked a treat the program is working better now. I have just realised that my for loopcontaining my counter may be in the wrong place as the program is running though both messages 3 times e.g
"Please enter your guess between 1 & 10"
"Try again"
"Please enter your guess between 1 & 10"
"Try again"
"Please enter your guess between 1 & 10"
"Try again"
"Please enter your guess between 1 & 10"
"Try again"
I want my program to run like
"Please enter your guess between 1 & 10"
"Try again"
"Try again"
"Try again"
Do u think if i placed my for stament (counter) in between the two messages it would eliminate this problem.

          boolean result = false;
          char [][] array = this.getArray();
          if (array[row][col] != '+' && ???? )
               result = true;
          return result;
     }I don't know how to solve for the current path

What sort of visa card is it, debit or credit ? If it's a debit card then I don't think that they are still accepted as a valid payment method in all countries - from this page :
You may be able to use other payment types in your country, like debit and Maestro cards.
which implies that they are not accepted in all countries, and there have been a number of posts about them being declined.
You haven't changed the address on your iTunes account (a card needs to be registered to exactly the same name and address, including format and spacing etc, that you have on your iTunes account) and you are still in the country where the card was issued ? You could check with the card issuer to see if it's them that are declining it, and if not then try contacting iTunes support and see if they know why it's being declined : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management

I need help with this recursion method

     public boolean findTheExit(int row, int col) {
          char[][] array = this.getArray();
          boolean escaped = false;
          System.out.println("row" + " " + row + " " + "col" + " " + col);
          System.out.println(array[row][col]);
          System.out.println("escaped" + " " + escaped);
          if (possible(row, col)){
               System.out.println("possible:" + " " + possible(row,col));
               array[row][col] = '.';
          if (checkBorder(row, col)){
               System.out.println("check border:" + " " + checkBorder(row,col));
               escaped = true;
          else {
                System.out.println();
                escaped = findTheExit(row+1, col);
                if (escaped == false)
                escaped = findTheExit(row, col+1);
                else if (escaped == false)
                escaped = findTheExit(row-1, col);
                else if (escaped == false)
                escaped = findTheExit(row, col-1);
          if (escaped == true)
               array[row][col] = 'O';
          return escaped;
     }I am having difficulties with this recursion method. What I wanted here is that when :
if escaped = findTheExit(row+1, col); I am having trouble with the following statement:
A base case has been reached, escaped(false) is returned to RP1. The algorithm backtracks to the call where row = 2 and col = 1 and assigns false to escaped.
How do I fix this code?
I know what's wrong with my code now, even though that if
if (possible(row, col))
[/code[
returns false then it will go to if (escaped == false)
               escaped = findTheExit(row, col+1);
how do I do this?

Okay I think I got the problem here because I already consult with the instructor, he said that by my code now I am not updating my current array if I change one of the values in a specific row and column into '.' . How do I change this so that I can get an update array. He said to me to erase char[][] array = getArray and replace it with the array instance variable in my class. But I don't have an array instance variable in my class. Below is my full code:
public class ObstacleCourse implements ObstacleCourseInterface {
     private String file = "";
     public ObstacleCourse(String filename) {
          file = filename;
     public boolean findTheExit(int row, int col) {
          boolean escaped = false;
          //System.out.println("row" + " " + row + " " + "col" + " " + col);
          //System.out.println(array[row][col]);
          //System.out.println("escaped" + " " + escaped);
          if (possible(row, col)){
               //System.out.println("possible:" + " " + possible(row,col) + "\n");
               array[row][col] = '.';
               if (checkBorder(row, col)){
               escaped = true;
               else {
                escaped = findTheExit(row+1, col);
                if (escaped == false)
                escaped = findTheExit(row, col+1);
                else if (escaped == false)
                escaped = findTheExit(row-1, col);
                else if (escaped == false)
                escaped = findTheExit(row, col-1);
          if (escaped == true)
               array[row][col] = 'O';
          return escaped;
     public char[][] getArray() {
          char[][] result = null;
          try {
               Scanner s = new Scanner(new File(file));
               int row = 0;
               int col = 0;
               row = s.nextInt();
               col = s.nextInt();
               String x = "";
               result = new char[row][col];
               s.nextLine();
               for (int i = 0; i < result.length; i++) {
                    x = s.nextLine();
                    for (int j = 0; j < result.length; j++) {
                         result[i][j] = x.charAt(j);
          } catch (Exception e) {
          return result;
     public int getStartColumn() {
          char[][] result = this.getArray();
          int columns = -1;
          for (int i = 0; i < result.length; i++) {
               for (int j = 0; j < result[i].length; j++) {
                    if (result[i][j] == 'S')
                         columns = j;
          return columns;
     public int getStartRow() {
          char[][] result = this.getArray();
          int row = -1;
          for (int i = 0; i < result.length; i++) {
               for (int j = 0; j < result[i].length; j++) {
                    if (result[i][j] == 'S')
                         row = i;
          return row;
     public boolean possible(int row, int col) {
          boolean result = false;
          char[][] array = this.getArray();
          if (array[row][col] != '+' && array[row][col] != '.')
               result = true;
          return result;
     public String toString() {
          String result = "";
          try {
               Scanner s = new Scanner(new File(file));
               s.nextLine();
               while (s.hasNextLine())
                    result += s.nextLine() + "\n";
          } catch (Exception e) {
          return result;
     public boolean checkBorder(int row, int col) {
          char[][] array = this.getArray();
          boolean result = false;
          int checkRow = 0;
          int checkColumns = 0;
          try {
               Scanner s = new Scanner(new File(file));
               checkRow = s.nextInt();
               checkColumns = s.nextInt();
          } catch (Exception e) {
          if ((row + 1 == checkRow || col + 1 == checkColumns) && array[row][col] != '+')
               result = true;
          return result;
I thought that my problem would be not to read the file using the try and catch everytime in the method. How do I do this?? Do I have to create an array instance variable in my class?
