Getting the TableModel of a JTable

Hi there!
I've got a JTable that was created via a class JCatalogTable that extends a so called JAbstractTable (this class extends JTable). In JCatalogTable the AbstractTableModel is set via super(TableModel) to the JAbstractTable. The AbstractTableModel is not the "normal" AbstractTableModel but a class called CatalogTableModel extending the AbstractTableModel.
This classes are all extending the normal Model because they display a special type of data. However, there is Method in the CatalogTableModel I have to call. My problem now is to get the Model to call the method.
What I have is an instance of JAbstractTable (a JTable). But I can only get the standard AbstractTableModel, if I try to cast to the CatalogTableModel I get a ClassCastException. Maybe anyone understands what I want and can give me a hin how to solve.
At last, here is my relevant code:
// jt_c is the JTable I'm working on
         JAbstractTable jat_c = (JAbstractTable) jt_c;
         AbstractTableModel atm_jat_c = (AbstractTableModel) jat_c.getModel(); // this works
         CatalogTableModel ctm_jat_c = (CatalogTableModel) atm_jat_c; // this gives a class cast exception

Well, it prints
class data.swing.CatalogTableModelBut I now wrote a get-Method in the JAbstractTable getATM()
    public AbstractTableModel getATM() {
         return atm; // atm is declared in the whole class
    }and then with
CatalogTableModel cm = (CatalogTableModel) jat_c.getATM();I have the CatalogTableModel.
Thanks for your contributions!

Swing: when trying to get the values from a JTable inside an event handler

Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

How can I get the JCheckBox value in JTable?

I have a JTable with JCheckBox inside. How can I get the value when the user turn on or off the check? I need to do this when the user change the value.
Thanks for any help.

Hi again,
no - the datamodel is a class that implements the TableModel-interface - if you do not use your own model in JTable, an instance of DefaultTableModel is used - you can subclass DefaultTableModel and overwrite its setValueAt(...)-method. When you instantiate your JTable do it by passing your DefaultTableModel subclass to the constructor or in the way you do it right now and replace the default model with your model using the setModel(...)-method of JTable.

How to get the data from a jtable with random order??

hi everyone,
i have a jtable i filled with Strring and Float data, i put this data to a MySQL database, and i use vectors and iterators to filled the database. the problem is there are some cells that are empty, and the Floats' columns throws me nullpointerexceptions.
please if anyone know how to avoid that exception i'd would be great.
thanks for your time.

HI Siggi,
Thank you for your reply..
I am also planning to do FM to get the data. But it is saying that the Cluster table ZES does not exist (ZES is the the standard table, in SE11 also).
How can I use the Fields from the that table.?
What can I do now, can you please explain me about this point.
Waiting for your reply.
Thanks and Regards

Cant get the last row in jtable

Hello all.
I am trying to get the last row from the table but get "" from it.
my table has 6 rows and i can get all rows right but the last line I have a problem.

If it hadn't found the row, I expect you would have got an Exception

Getting the Difference in JTables my algo is messed

Im trying to get the difference of two JTables...in other words if Table B has the rowdata of Table A, then Table C should not have it...Table C should have all the data in Table A - the data in Table B
heres my code:
//in a subclass of JTable
public Object[][] getDifferenceData(JTable table){
    DefaultTableModel thisModel = (DefaultTableModel)this.getModel();
    DefaultTableModel userModel = (DefaultTableModel)table.getModel();
    int differenceRows = thisModel.getRowCount() - userModel.getRowCount();
    Object[][] newData = new Object[differenceRows][2];
    Object symbol = new Object();
    Object description = new Object();
     for (int i=0; i<differenceRows; i++){
        for (int j=0; j<userModel.getRowCount()-1; j++){
            if ((symbol = thisModel.getValueAt(i,0)) != userModel.getValueAt(j,0)){
                //symbol in portfolio model != symbol in user portfolio
                //so new difference table model should have it
                description = thisModel.getValueAt(i,1);
                newData[0] = symbol;
newData[i][1] = description;
return newData;
heres what im trying to do
1) new Data[][] is set to size bigger table row count - smaller tables
for all new row size
2)compare table A data in the current row and first column to all the rows/first column of table B
3) if the data is NOT the same, the copy that row data from Table A into a new 2D data vector to the appropriate row
4) return the new data[][] for new jtable creation
but what happens is that the difference table (C) contains the corrent number of rows...but it still contains the data found in table B, and the new table C is just table C with the right number of rows cut off
my algo is severly messed :)
any help would be appreciated..thanks

hey klepto,
your not using .equals() on the symbol Object, this means that all it is doing is seeing if they refer to the same instance of the object, not if the to instances have the same value.
The other problem is that you presume that the difference of the two collections is based on their respective size. What if they contain totaly different values? Then the total size would be the sum of both collections.
Lets presume that the symbol is a String. Then I would do the following:
//in a subclass of JTable
public Object[][] getDifferenceData(JTable table, DefaultTableModel thisModel, DefaultTableModel userModel){
    Object[][] newData = null;
    String symbolA = null;
    String symbolB = null;
    String description = null;
    SymbolData symbolData = null;
    Vector newList = new Vector();
    int nbrRowsA = thisModel.getRowCount();
    int nbrRowsB = userModel.getRowCount();
    for(int i = 0; i < nbrRowsA; i++) {
        symbolA = (String)thisModel.getValue(i, 0);
        for(int j = 0; j < userModel.getRowCount() - 1; j++) {
            symbolB = (string)userModel.getValue(i, 0);
            if(!symbolA.equals(symbolB)){
                description = (String)thisModel.getValueAt(i,1);
                newList.add(new SymbolData(symbol, description));
    if(newList.size() > 0) {
        int size = newList.size();
        newData = new String[size][2];
        for(int i = 0; i < size; i++) {
            symbolData = (SymbolData)newList.get(i);
            newData[0] = symbolData.getSymbol();
newData[i][1] = symbolData.getDescription();
return newData;
class SymbolData {
String symbol;
String description;
MyDataClass(String symbol, String description) {
this.symbol = symbol;
this.description = description;
String getSymbol() {
return symbol;
String getDescription() {
return description;
String[] getData() {
String[] data = new String[2];
data[0] = symbol;
data[1] = description;
return data;
Hmm, that should do the job. Not the fastest code, I'm sure there
could be some improvements with the array handling. But it should
get you started.
Also I have not attempted to compile the above so I suspect you
will find problems (only on a good day do I get zero compile errors
when I first write something, good days are rare :-) ).

How can I get the edited value from the editor in JTable

I have a JTextField added as an editor to a cell in JTable.
I value gets changed when I press enter.
but in actionPerformed of the JTextField when I say
String txtEditorValue = txtEditor.getText();
I am getting the old value. How can I get the edited value? Thanks.

Hi,
I guess, your understanding of how JTable works together with its models is not good enough - for example the method getTableCellEditorComponent(...) of the TableCellEditor interface is used to get the component, that should be used as editing component - its second parameter is a value that should be used to setup the editing component - it is normally not the editing component itself.
JTable uses an underlying TableModel to store the cell values - if you have edited a cell, JTable gets the value of the editing component by itself and stores it in the TableModel using its setValueAt(...) method. To retrieve this data you only need to query the TableModel using row and column of this cell as parameters
say jt is your JTable, and row and column are the row and column of the cell - so to get the value, simply use
Object obj = jt.getModel().getValueAt(row,column);
if you know, that there is a String in this cell use
String str = (String) jt.getModel().getValueAt(row,column);
The editor component is used for the view of the JTable - you only want the data, which is stored in the model - you don't have to deal with the GUI components in this case.

(JTable) How can i get the first columns cell in a selected row?

Hello. I am trying to figure out how i can get the first columns cell within a selected row no matter what cell is selected in that row. I have a class that extends AbstractTableModel which represents the table. Now i have another class that extends DefaultSelectionModel. Each model is added to the JTable via setModel(TableModel dataModel), setSelectionModel(ListSelectionModel newModel). Now i don't understand what i have to return from getMaxSelectionIndex(). Any ides? Thanks.
class xTableModel extends AbstractTableModel{
     private static String[] cols;
     private Object[][] data;
        public void setTableModel(Object data[][], String[] cols){
         this.cols = cols;
         this.data = data;
        public String getColumnName(int col){
         return cols[col];
        public int getRowCount() {
         return data.length;
        public Object getValueAt(int row, int col) {
         return data[row][col];
        public void setValueAt(Object value,int row,int col){
         data[row][col]=value;
        public int getColumnCount(){

Getting the user input from a JTables Columns

Hello
I am having real trouble with this could someone please help?
I have to columns on my JTable (first name , lastname).
How can I loop though each column like this?
the first column (first names), and get each row and add it to a String array?
for example if the user puts in 10 firstnames I want to add all 10 to a string array.
and for the second column, I want to add all the rows (last names ), to a arraylist. so if the user puts in 10 lastnames, I want to add them to the arraylist.
How can I do this?
thanks
bobby

JTable table = new JTable();
TableModel model = table.getModel();
int row = 0;
int col = 0;
//You can loop using the line below to get the values for each cell
//I'm casting it as a String, if you don't have a String, you can leave
// it as an Object
String s = (String) model.getValueAt(row, col);

How to get the value from a cell in jTable without click "enter" or "tab"

Hi guys,
I have a simple question. I have a jTable in my screen and when editing a value, but without click "enter" or "tab" I want to get the new value. I have a button update and after editing the value I click the button "update" and I want the new value to be store in my table. If try to get the selected value it is giving the old value. How can I implement this? Any idea? I hope I was clear.

How to get the last value edited by users from JTable?

Hi.
I have a JDialog that includes an editable JTable. This table is used to set up field caption and font for a report program. I found only when cursor is moved to another cell, the value in current cell being edited will be transferred to Table Model. So if the user don�t move cursor to another cell after editing the value of a cell but click OK button directly, Table Model cannot get the last value edited by the user, I wonder if there is a way to fire JTable to transfer the value being edited to Table model.
By the way, I found if the TableCellEditor is using JCheckBox or JComboBox instead of JTextField, there is no this problem.
Thank you for any reply.

I guess you can make use of the following methods on your table model to inform it make it getValueAt bcos table data has changed.
fireTableCellUpdated
Notifies all listeners that the value of the cell at [row, column] has been updated.
fireTableChanged
Forwards the given notification event to all TableModelListeners that registered themselves as listeners for this table model.
fireTableDataChanged
Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.
But when to call these methods??
-- When OK button is pressed, do this as the first thing!!
OR
-- Call this on every key event!!

How to get the default selection color from JTable

Hi, there,
I have a question for how to get the default selection color from JTable. I am currently implementing the customized table cell renderer, but I do want to set the selection color in the table exactly the same of default table cell renderer. The JTable.getSelectionBackgroup() did not works for me, it returned dark blue which made the text in the table unreadable. Anyone know how to get the window's default selection color?
Thanks,
-Jenny

The windows default selection color is dark blue. Try selecting any text on this page. The difference is that the text gets changed to a white font so you can actually see the text.
If you don't like the default colors that Java uses then use the UIManager to change the defaults. The following program shows all the properties controlled by the UIManager:
http://www.discoverteenergy.com/files/ShowUIDefaults.java
Any of the properties can be changed for the entire application by using:
UIManager.put( "propertyName", value );

JTable problem : how to get the last value entered by user + event lost

Hi all,
I have 2 problems with Jtable class.
1 => To get the last value entered by user in a cell,
it seems that we must change the selected cell.
That is to say we can only have the previous cell's value.
Is there a simple way to get the current value of any cell ?
2 => To resolve the problem i store the values of each cell in a vector and i intercept keyboard event (!)
BUT, when i do a double click with the mouse on the Jtable, i loose keyboard events. Then, i can't intercept them.
Is it a bug of swing or am i following a wrong way ?
Thanks by anticipation for your help.

You have to fire the "TableCellUpdatedEvent"
and override the getCellEditorValue in TableCellEditor to return the current value
